Factors affecting microbial formation of nitrate-nitrogen in soil and their effects on fertilizer nitrogen use efficiency. (1/13)

Mineralization of soil organic matter is governed by predictable factors with nitrate-N as the end product. Crop production interrupts the natural balance, accelerates mineralization of N, and elevates levels of nitrate-N in soil. Six factors determine nitrate-N levels in soils: soil clay content, bulk density, organic matter content, pH, temperature, and rainfall. Maximal rates of N mineralization require an optimal level of air-filled pore space. Optimal air-filled pore space depends on soil clay content, soil organic matter content, soil bulk density, and rainfall. Pore space is partitioned into water- and air-filled space. A maximal rate of nitrate formation occurs at a pH of 6.7 and rather modest mineralization rates occur at pH 5.0 and 8.0. Predictions of the soil nitrate-N concentrations with a relative precision of 1 to 4 microg N g(-1) of soil were obtained with a computerized N fertilizer decision aid. Grain yields obtained using the N fertilizer decision aid were not measurably different from those using adjacent farmer practices, but N fertilizer use was reduced by >10%. Predicting mineralization in this manner allows optimal N applications to be determined for site-specific soil and weather conditions.  (+info)

Nitrogen fertilizer rate and crop management effects on nitrate leaching from an agricultural field in central Pennsylvania. (2/13)

Eighteen pan lysimeters were installed at a depth of 1.2 m in a Hagerstown silt loam soil in a corn field in central Pennsylvania in 1988. In 1995, wick lysimeters were also installed at 1.2 m depth in the same access pits. Treatments have included N fertilizer rates, use of manure, crop rotation (continuous corn, corn-soybean, alfalfa-corn), and tillage (chisel plow-disk, no-till). The leachate data were used to evaluate a number of nitrate leaching models. Some of the highlights of the 11 years of results include the following: 1) growing corn without organic N inputs at the economic optimum N rate (EON) resulted in NO3--N concentrations of 15 to 20 mg l(-1) in leachate; 2) use of manure or previous alfalfa crop as partial source of N also resulted in 15 to 20 mg l(-1) of NO3--N in leachate below corn at EON; 3) NO3--N concentration in leachate below alfalfa was approximately 4 mg l(-1); 4) NO3--N concentration in leachate below soybeans following corn was influenced by fertilizer N rate applied to corn; 5) the mass of NO3--N leached below corn at the EON rate averaged 90 kg N ha(-1) (approx. 40% of fertilizer N applied at EON); 6) wick lysimeters collected approximately 100% of leachate vs. 40-50% collected by pan lysimeters. Coefficients of variation of the collected leachate volumes for both lysimeter types were similar; 7) tillage did not markedly affect nitrate leaching losses; 8) tested leaching models could accurately predict leachate volumes and could be calibrated to match nitrate leaching losses in calibration years, but only one model (SOILN) accurately predicted nitrate leaching losses in the majority of validation treatment years. Apparent problems with tested models: there was difficulty estimating sizes of organic N pools and their transformation rates, and the models either did not include a macropore flow component or did not handle macropore flow well.  (+info)

A new approach to determine the total airborne N input into the soil/plant system using 15N isotope dilution (ITNI): results for agricultural areas in Central Germany. (3/13)

The atmospheric deposition of nitrogen (N) in the environment is of great concern due to its impact on natural ecosystems including affecting vegetation, reducing biodiversity, increasing tree growth in forests, and the eutrophication of aquatic systems. Taking into account the average annual N emission into the atmosphere in Germany of about 2 million t N (ammonia/ammonium, NOx), and assuming homogeneous distribution throughout Germany, an average N deposition of 45 kg/ha x year can be calculated. Such high atmospheric N deposition could be confirmed by N balances from long-term field experiments in Central Germany (e.g., the Static Fertilization Experiment in Bad Lauchstdt). By contrast, estimates by standard methods indicate a deposition of only about 30 kg N/ha x year. This is because the standard methods are using wet-only or bulk collectors, which fail to take into account gaseous deposition and the direct uptake of atmospheric N by aerial plant parts. Therefore, a new system was developed using 15N isotope dilution methodology to measure the actual total atmospheric N input into a soil/plant system (Integrated Total Nitrogen Input, ITNI). A soil/plant system is labeled with [15N]ammonium-[15N]nitrate and the total input of airborne N is calculated from the dilution of this tracer by N from the atmosphere. An average annual deposition of 64 +/- 11 kg/ha x year from 1994-2000 was measured with the ITNI system at the Bad Lauchstdt research farm in the dry belt of Central Germany. Measurements in 1999/2000 at three other sites in Central Germany produced deposition rates of about 60 kg/ha x year. These data clearly show that the total atmospheric N deposition into the soil/plant system determined by the newly developed ITNI system significantly exceeds that obtained from standard wet-only and bulk collectors. The higher atmospheric N depositions found closely match those postulated from the N balances of long-term agricultural field experiments.  (+info)

Use and misuse of nitrogen in agriculture: the German story. (4/13)

Nitrogen (N) fertilization in agriculture has been discussed controversially in Germany for almost two centuries. The agronomist Carl Sprengel, who published his theory on the mineral nutrition of plants in 1828, advocated the use of mineral N fertilizers. Chemist Justus von Liebig, on the other hand, vehemently denied around 1850 the need for N fertilization. Although it soon became evident that Sprengel was right and Liebig was wrong, not much synthetic N fertilizer was used in German agriculture until around 1915, when the Haber-Bosch technique enabled the commercial production of NH3. The use of N fertilizers since then has grown, especially since 1950. To increase agricultural productivity, German governments have promoted, directly and indirectly, the use of N in crop and in animal production. Unfortunately, it was overlooked that N surpluses in agriculture increased rapidly; around 1980 they amounted yearly to more than 100 kg ha(-1). The extensive use of N in agriculture is causing environmental damage and is contributing substantially to the external costs of present agriculture. The main N compounds that affect the environment are N2O, NH3, and NO3. These compounds are considered to contribute one third to the external costs of agriculture. Additionally, the high rate of human intake of animal proteins and lipids has adversely affected the health of the country's population. Fundamental corrections in German farm policy appear inevitable.  (+info)

Effect of triclosan or a phenolic farm disinfectant on the selection of antibiotic-resistant Salmonella enterica. (5/13)

OBJECTIVE: To determine the effect of growth of five strains of Salmonella enterica and their isogenic multiply antibiotic-resistant (MAR) derivatives with a phenolic farm disinfectant or triclosan (biocides) upon the frequency of mutation to resistance to antibiotics or cyclohexane. METHODS: Strains were grown in broth with or without the biocides and then spread on to agar containing ampicillin, ciprofloxacin or tetracycline each at 4x MIC or agar overlaid with cyclohexane. Incubation was for 24 and 48 h and the frequency of mutation to resistance was calculated for strains with and without prior growth with the biocides. MICs were determined and the presence of mutations in the acrR and marR regions was determined by sequencing and the presence of mutations in gyrA by light-cycler analysis, for a selection of the mutants that arose. RESULTS: The mean frequency of mutation to antibiotic or cyclohexane resistance was increased approximately 10- to 100-fold by prior growth with the phenolic disinfectant or triclosan. The increases were statistically significant for all antibiotics and cyclohexane following exposure to the phenolic disinfectant (P 1 mg/L ciprofloxacin arose only from strains that were MAR. Reduced susceptibility to ciprofloxacin (at 4x MIC for parent strains) alone was associated with mutations in gyrA. MAR mutants did not contain mutations in the acrR or marR region. CONCLUSIONS: These data renew fears that the use of biocides may lead to an increased selective pressure towards antibiotic resistance.  (+info)

Screening analyses of pinosylvin stilbenes, resin acids and lignans in Norwegian conifers. (6/13)

The content and distribution of stilbenes and resin acids in Scots pine (Pinus sylvestris) and spruce (Picea abies), sampled in central Norway, have been examined. The contents of pinosylvin stilbenes in pine heartwood/living knots were 0.2-2/2-8 %(w/w). No stilbenes could be detected in spruce (Picea abies). The resin acid contents of pine sapwood/heartwood and knots were 1-4 and 5-10 % (w/w), respectively. Minor amounts of resin acids (<0.2/<0.04 %w/w) were identified in spruce wood/knots. The lignan content in knots of Norwegian spruce was 6.5 % (w/w). Diastereomerically pure hydroxymatairesinol (HMR, 84 % of total lignans) was readily isolated from this source since only minor quantities (2.6 % of total lignans) of the allo-HMR diastereomer was detected. Insignificant amounts of lignans were present in the sapwood. Lignans could not be detected in the sapwood or knots of Norwegian sallow (Salix caprea), birch(Betula pendula) or juniper (Juniperus communis).  (+info)

25 years of natural product R&D with New South Wales agriculture. (7/13)

Following recent NSW Government restructuring, the Department of Agriculture now exists in a composite form along with Forestry, Fisheries and Minerals in the new NSW Department of Primary Industries. This paper outlines some of the highlights of secondary metabolite R&D accomplished in the 25 years since the essential oil research unit was transferred from the Museum of Applied Arts & Sciences, Sydney to NSW Agriculture's Wollongbar Agricultural Institute on the NSW north coast. The essential oil survey was continued, typing the Australian flora as a suitable source of isolates such as myrtenal (Astartea), myrtenol (Agonis), methyl chavicol(Ochrosperma), alpha-phellandren-8-ol (Prostanthera), methyl myrtenate (Darwinia), methyl geranate (Darwinia), kessane (Acacia), cis-dihydroagarofuran (Prosthanthera), protoanemonin (Clematis), isoamyl isovalerate (Micromyrtus), methyl cinnamate (Eucalyptus) and bornyl acetate (Boronia). Many of these components are used, or have potential use in the fragrance, flavour, medicinal plant or insect attraction fields. Two weeds toxic to livestock in the Central West of the State are also harvested commercially as medicinal plants. Measurement of hypericin concentrations in the various plant parts of St John's Wort (Hypericum perforatum) over two seasons has shown that the weed can be effectively managed by grazing sheep during the winter months when toxin levels are low. Syntheses of beta-carbolines tribulusterine and perlolyrine have shown that the former alkaloid was misidentified in the literature and hence not the toxic principle responsible for Tribulus staggers in sheep. Poor quality (high 1,8-cineole - low terpinen-4-ol) oil bearing tea tree (Melaleuca alternifolia) plantations have been established to the detriment of many a tea tree farmer. Analytical methods developed to check leaf quality at an early age indicated precursor sabinene constituents that convert to the active terpinen-4-ol both as the leaf matures or as the precursors are distilled for oil production. Tea tree's major insect pest, pyrgo beetle (Paropsisterna tigrina), was seen to selectively metabolize only 1,8-cineole from it's monoterpenoid-rich diet. Characterization of these and other metabolites from myrtaceous herbivores showed a species specific production of predominately ring hydroxylated products, some of which were attractive when bioassayed against adult beetles.  (+info)

The 15N isotope to evaluate fertilizer nitrogen absorption efficiency by the coffee plant. (8/13)

The use of the 15N label for agronomic research involving nitrogen (N) cycling and the fate of fertilizer-N is well established, however, in the case of long term experimentation with perennial crops like citrus, coffee and rubber tree, there are still shortcomings mainly due to large plant size, sampling procedures, detection levels and interferences on the system. This report tries to contribute methodologically to the design and development of 15N labeled fertilizer experiments, using as an example a coffee crop fertilized with 15N labeled ammonium sulfate, which was followed for two years. The N of the plant derived from the fertilizer was studied in the different parts of the coffee plant in order to evaluate its distribution within the plant and the agronomic efficiency of the fertilizer application practice. An enrichment of the fertilizer-N of the order of 2% 15N abundance was sufficient to study N absorption rates and to establish fertilizer-N balances after one and two years of coffee cropping. The main source of errors in the estimated values lies in the inherent variability among field replicates and not in the measurements of N contents and 15N enrichments of plant material by mass-spectrometry.  (+info)

The synthesis and evaluation of structural analogues and isosteres are of central importance in medicinal and agricultural chemistry. The sulfonamide functional group represents one of the most important amide isosteres in contemporary drug design, and about 500 such compounds have overcome both the pharmacological and regulatory hurdles that precede studies in humans. The mono aza analogues of sulfonamides, that is, sulfonimidamides, are rapidly gaining popularity as a novel functional group among synthetic chemists involved in the design of biologically active compounds for both pharmaceutical and agrochemical applications. Herein, we review these recent developments to showcase the promise of this functional group.. ...

The Future of the Supply of Plant-Food.-Vice-President Wiley began his address before the Chemical Section of the American Association-which was on "The Economical Aspect of Agricultural Chemistry"-with a rough estimate of the money value of the potash, phosphoric acid, and nitrogen contained in a single harvest, the total of which he placed at $3,343,786,050. This seems to be an enormous quantity of plant-food to be removed from the soil annually, but it must be remembered that it is not all lost; much of it is left in the soil in roots, straw, stalks, etc. But too often the débris is got rid of as quickly as possible, and we have in practice not tilling but killing the soil. The stores of plant-food which have accumulated in our virgin soils are indeed great, but they can not withstand this constant drain upon them. The potash that is in the soil may be estimated as enough to last two hundred and fifty years, and the phosphoric acid two hundred and twenty-five years. Immense reserves of both ...
Originally a subdivision of chemistry but now an independent science, biochemistry includes all aspects of chemistry that apply to living organisms. Thus, photochemistry is directly involved with photosynthesis and physical chemistry with osmosis... two phenomena that underlie all plant and animal life. Other important chemical mechanisms that apply directly to living organisms are catalysis, which takes place in biochemical systems by the agency of enzymes; nucleic acid and protein constitution and behaviour, which is known to control the mechanism of genetics; colloid chemistry, which deals in part with the nature of cell walls, muscles, collagen, etc; acid-base relations, involved in the pH of body fluids; and such nutritional components as amino acids, fats, carbohydrates, minerals, lipids and vitamins, all of which are essential to life. The chemical organisation and reproductive behaviour of microorganisms (bacteria and viruses) and a large part of agricultural chemistry are also included ...

The Mansfeld region in Sachsen-Anhalt, Central Germany, has a long tradition of mining Kupferschiefer, a marine copper-containing black shale of Permian age. One of the residues from the processing of that low-grade copper ore is Theisen Sludge, a very fine-grained scrubber dust composed of metal sulphide particles in a matrix of highly viscous hydrocarbons. The Theisen Sludge is considered to be the main source for heavy metal releases into the local environment. The most important discharge point for contaminated water is the Stadtborn Spring. The extremely high metal and sulphate concentrations in the spring water cause the precipitation of a mineral phase exceptionally rich in heavy metals. This precipitate is the focus of the current investigation. It is shown that a gel with adsorbed metals first is formed from spring water. Then zinc-copper-aluminium hydroxides start to crystallise from the gel at an early stage, forming (Zn,Cu,Al)(O,OH)2 brucite-type layers, which are positively ...

Yellow leaves can be caused by many things including lack of nitrogen, insufficient light, water-logged soil (plant roots need oxygen to thrive), dry soil, or iron deficiency. If the older bottom leaves are yellow, but new growth is green, its usually a lack of nitrogen. If new leaves are yellow, with green veins, its usually a lack of iron. (Lack of nitrogen is a more common problem than lack of iron.) Soil should be kept moderately moist (but not wet). Finally, a cold snap can injure the leaves; they will wilt suddenly and then drop off the plant ...

Table 1 and Table 2 display a comparison of the methods presented to provide the reader with a quick reference.. Charlesworth (2000) presents a Value Selection Method suggested by Cape (1997) to decide which soil moisture measuring technique is most applicable to a particular situation. This procedure consists of answering a number of questions (Yes = 1, No = 0) (Table 3). The relative importance of each question is quantified with appropriate weights, and a total relative importance (T) of each sensor for a specific application is obtained by adding the individual scores from all questions and multiplying it by the score for the "effective range of measurement" criterion. This multiplication factor (0 or 1) is a modification of the original method proposed here. This implies that no sensor will be valid for an application if the field measuring range does not match the sensors specifications. The total estimated life cost of the sensor (Cost) is estimated from capital, installation, running, ...

A grazed trial established in 1980 evaluated the effects of superphosphate fertiliser application on pasture growth on Easy (10°-20° slope) and Steep (30°-40° slope) land in the Waikato, North Island, New Zealand.. Continuous and rotational grazing showed no effects on pasture responses to fertiliser. Mean annual pasture dry matter (DM) production ranged from 11,275 to 14,155 kg DM ha−1 on Easy, and 6413 to 7480 kg DM ha−1 on Steep slopes through the range of 10-100 kg ha−1 yr−1 of phosphate (P) fertiliser rates. Initial fertiliser effects on Olsen P tests were in the 0-3 cm depth only, and in the 7-15 cm soil depth only in the 100 kg ha−1 yr−1 treatment by year 4. Near maximum (97%) annual production, derived from relative yield analysis, was obtained at 0-7 cm depth soil tests of 30 on Easy slopes and at 12 on Steep slopes.. Results from this trial are directly relevant to the variable fertiliser rate aerial application technology currently being developed.. ...

The substances with the lowest molecular weights in the category are Resin acids and rosin acids, Me esters and Resin acids and rosin acids, hydrogenated, Me esters. The lowest EC50 available for these substances is 27 mg/L, from a Daphnia study with the test material Resin acids and rosin acids, hydrogenated, Me esters (Inveresk 2002). This result is read across to Resin acids and rosin acids, Me esters for classification purposes. As this EC50 is , 1 mg/L an acute environmental classification is not appropriate. Neither Resin acids and rosin acids, Me esters or Resin acids and rosin acids hydrogenated Me esters are readily biodegradable therefore as the lowest EC50 is ,10 ,100 mg/L a chronic classification of Chronic Category 3 is applied for both substances in accordance with the CLP regulation. Both substances are classified as R52 -53 under the DSD. ...
The mtDNA frequency analysis presented in this report revealed close genetic association, at the mtDNA level, between TC and European Neo-Eneolithic farming groups, particularly those from central and northern Europe, including representatives of the Funnel Beaker/TRB complex such as Funnel Beakers from Scandinavia (FBC [23-27]) as well as the Baalberge (BAC) and Salzmünde (SMC) Funnel Beaker groups from central Germany (Fig 1). Like TC, the FBC group lacked representatives of hunter-gatherer lineages of haplogroup U such as U5, while the U5 component in the BAC and SMC populations comprised less than 5% of the mtDNA haplogroup variety. All three abovementioned European Funnel Beaker groups featured representatives of haplogroup H at or over 25% frequency, as well as having representatives of haplogroups J and T2b. The BAC and SMC populations also contained individuals belonging to haplogroup HV. The similarity in mtDNA lineage composition between TC and the Funnel Beaker/TRB culture complex ...

Eastern Star performs best when produced in a growing medium with both good water-holding capacity and drainage characteristics. When planting, be careful to not plant the plugs too deeply, as this could lead to crown rot. I recommend applying a fungicide drench such as Subdue Maxx or OHP 6672 (Clearys 3336 and FungoFlo contain the same active ingredient as OHP 6672), or drench a combination of ç these two fungicides immediately after transplanting.. Eastern Star is a moderate feeder and grows well under constant liquid fertilizer programs with fertilizer rates of 50-100 ppm nitrate. Growers using controlled-release fertilizers get the best results by incorporating at a rate equivalent to 1 lb. of nitrogen per yard of growing medium or by topdressing at the medium recommended rates. For example, if your time-release fertilizer formulation is 15-9-12, meaning it contains 15 percent nitrogen; you would need to incorporate 7 lbs. of this product per yard of media to obtain 1 lb. of elemental ...
Grow Time (From Rooted Cutting) Lantanas in a quart container with one plant per pot take seven to eight weeks, in a gallon container with two plants per pot and also in a 12-inch baskets with four to five plants per pot, 11 to 12 weeks of grow time. Pinching Only one pinch is needed for compact lantanas like Bandana, either late in propagation or after transplant. Try to leave two or more sets of nodes when pinching. For more vigorous varieties like Bandana Trailing Gold, two pinches are best. Growing Media High quality media with good porosity is critical for best growth. Peat-based mixes, like Fafard 2 Mix or 1P Mix, or bark-based mixes, like Fafard 4P Mix or 3B Mix work well. Fertilizer Rate Apply 200 to 250 parts per million (ppm) nitrogen, using Cal-Mag fertilizers (i.e. 13-2-13,15-5-15,14-4-14, etc.) for more compact growth and neutral pH. Use high […] ...

Fertilizer nitrogen use efficiency (NUE) was high in all site-years and well above national averages. NUE was particularly influenced by the amount of residual nitrate-nitrogen present in the soil profile prior to planting. At Site 1, NUE tended to be highest with the strategy that combined variable rate nitrogen with uniform seed density. At Site 2 in 2003, there was no advantage to variable rate nitrogen in NUE, while in 2004 a variable rate strategy which applied more nitrogen in high-yielding areas of the field resulted in the highest NUE.. At Site 1 in 2003, variable rate nitrogen management increased the gross economic return above fertilizer costs. However, for the other three site-years, there were no significant effects of site-specific management on profitability. The conclusion of the study was that, using the strategies the researchers selected, they could not demonstrate consistent significant economic benefits to site-specific management. One site-year did indicate an economic ...

An offset printing plate precursor comprising a substrate having provided thereon a layer containing a substance capable of absorbing radiant rays and converting the radiant energy to heat energy, and a thin layer, wherein printing is performed by following the steps of: (a) subjecting the printing plate precursor to irradiation with active light, (b) subjecting the printing plate precursor to irradiation with light/heat convertible radiant rays or heat treatment, to thereby imagewise distribute a hydrophilic area and a lipophilic area of the thin layer, and (c) bringing the thin layer into contact with printing ink to form a printing plate in which the lipophilic area has received the printing ink, to thereby perform offset printing.
In order to evaluate the impact of different amounts of nitrogen fertilizer on growth and yield of two forage sorghum cultivars, a 2-year field experiment was carried out at the College of Agriculture, Shiraz University, Shiraz, Iran during 2010 and 2011 growing seasons. Two factorial experiments were carried out in randomized block design with three replicates, in which the treatments included nitrogen fertilizer at three levels: 69 (N1), 138 (N2) and 205 (N3) kg N ha-1 and two sorghum cultivars: Pegah and KFS2. The results showed that nitrogen fertilizer enhanced plant height, leaf area index, fresh weight, total dry weight and biological yield significantly so that these traits were higher in N3 as 5.71, 22.8, 8.13, 22.5, and 8.7% than N1, respectively. Furthermore, increasing nitrogen rate had additive effect on crop growth rate, relative growth rate, biomass duration and leaf area duration. Comparing the cultivars, it was found that, plant height, fresh weight, total dry weight and biological yield

Considering the tradeoff between achieving the highest profit and causing the lowest environmental impact, there is a need for a profound understanding of the economic consequences of nitrogen (N) fertilizer application. The present doctoral research provides comprehensive insights into (i) effects of site-specific N management (SSNM) on profitability and risk mitigation; (ii) impacts of uncertainties and risk implications on optimal N fertilizer rates; and (iii) potential and costs of mitigating greenhouse gas (GHG) emissions by N fertilizer reduction. A modelling approach was developed to simulate the response of yield, protein, economic and risk implications, and GHG emissions to N fertilizer application. Findings of the thesis show that SSNM improves profitability by achieving higher grain quality, thus, price premiums. SSNM reduces the risk of not reaching the baking grain quality and poses no considerable disadvantage on downside risk management compared to uniform management. Price ...

Nitrogen use efficiency (NUE) in maize (Zea mays L.) is an important trait to optimize yield with minimal input of nitrogen (N) fertilizer. Expired Plant Variety Protection (ex-PVP) Act-certified germplasm may be an important genetic resource for public breeding sectors. The objectives of this research were to evaluate the genetic variation of N-use traits and to characterize maize ex-PVP inbreds that are adapted to the U.S. Corn Belt for NUE performance. Eighty-nine ex-PVP inbreds (36 stiff stalk synthetic (SSS), and 53 non-stiff stalk synthetic (NSSS)) were genotyped using 26,769 single-nucleotide polymorphisms, then 263 single-cross maize hybrids derived from these inbreds were grown in eight environments from 2011 to 2015 at two N fertilizer rates (0 and 252 kg N ha−1) and three replications. Genetic utilization of inherent soil nitrogen and the yield response to N fertilizer were stable across environments and were highly correlated with yield under low and high N conditions, respectively.
Irrigated coarse textured soils have the potential to produce high yielding crops but are also likely to leach out fertilizer nutrients before they can be utilized. Few studies have considered split fertilizer applications of sulfur (S) and potassium (K) on coarse textured soils. Eight fertilizer studies, four S and four K, were conducted to assess how split applications of S and K fertilizers affect plant uptake, corn grain yield, and the leaching potential over the growing season. Each site had four at planting (AP) and four in-season (IS) fertilizer rates applied for a combination of 16 different fertilizer treatments. Various plant tissue, remote sensing readings, and soil samples were taken to assess nutrient availability and movement through the soil profile. Suction cup lysimeters were used in select treatments to monitor soil pore water concentrations. Single or split applications of S and K fertilizers did not increase grain yield. Significant differences among different AP and IS rates ...

Molybdenum is required both by plants and animals. In Ireland , shortage of the element is not a significant problem but on sphagnum peat soils some horticultural crops including swedes, cabbages and onions have responded to molybdenum applications (MacNaeidhe, private communication). Molybdenum deficiency would certainly not be expected on the majority of Irish midland cut-away peats as the high pH condition resulting from underlying calcareous parent materials would ensure that sufficient Mo was present in an available form. Under such conditions the problem is very often one of excess and many of our midland cut-away peats support molybdenum-toxic pastures. These give rise to problems particularly in young cattle when excess molybdenum in the herbage acts as an antagonist, which militates against efficient copper absorption by the animal.. From the soil/plant aspect it is essential to realise that this induced copper deficiency in animals can occur when values for both available soil copper ...

A. Introduction. Swatara Creek and its watershed have played an important and varied role in the history of south central Pennsylvania. From prehistoric times through today, the watershed has fulfilled the differing needs of its inhabitants. Early inhabitants utilized the watershed as primarily hunting and fishing grounds for their existence. Later, as European settlers colonized the watershed, it continued to provide for sustenance; but it also pro- vided lumber, agricultural soils, and transportation for building a life in the area. The following generations of settlers used the streams of the Swatara Creek watershed to power mills and transport while they harvested the coal, iron, and limestone along their banks, bringing economic prosperity to the area. Today, Swatara Creek and its watershed provide prime agricultural soil for farming, land for development, wildlife habitat, and recreational opportunities for both residents and visitors.. All of these needs and uses have had an impact on the ...

Ratings of oak populations revealed that around 90 % of all oak trees affected by viruslike symptoms showed chlorotic ringspots and that these symptoms are widely spread in oaks in north and central Germany. In this study the putative agent of these symptoms should be isolated and specified. Rod-shaped particles with a length of 450 nm were recovered from two different samples of leaves displaying chlorotic ringspots by mechanical inoculation of herbaceous indicator plants. These particles were identified to be Tobacco mosaic virus (TMV)- and Tomato mosaic virus (ToMV)- isolates by RT-PCR analyses of the coat- and movement protein genes. Infections with other well known viruses of forest trees, like Cherry leaf roll virus (CLRV) and the agent causing ringspots in European mountain ash, were excluded by ELISA and RT-PCR. DsRNA fragments of 1.5 and 1.6 kb as well as 1.8 and 2.0 kb were extracted from leaves, inner bark and bulbs of all symptomatic and asymptomatic samples of common oak. The ...
Borna disease virus-1 (BoDV-1) was recently discovered as cause of severe and often fatal encephalitis in humans. BoDV-1 is known to cause neurological disease in horses and sheep mainly in South and Central Germany. The virus is maintained in bicolored white-toothed shrews (Crocidura leucodon). The incidence of infection and risk factors in humans are completely unresolved. Veterinarians may be disproportionally BoDV-1-exposed through contact to animals not recognized to be BoDV-1 infected. We conducted three serosurveys predominantly in endemic areas of South Germany for the presence of BoDV-1-reactive antibodies. Anonymized residual samples from two serosurveys of veterinarians (n = 736) with interview data on exposures and one serosurvey among blood donors (n = 373) were screened with an indirect immunofluorescence antibody test, followed by a newly developed immunoblot as confirmatory assay.

Measurement of the apparent dielectric permittivity of soils (dielectric constant) is becoming a popular way of estimating soil volumetric water content. This paper focuses on the measurement of apparent permittivity in four sandy soils using; time domain reflectometry (TDR), a surface capacitance insertion probe (SCIP) and a Theta probe. Measurement of the apparent permittivity using the SCIP and Theta probe are compared with the apparent permittivity measured using the TDR. Calibration of such instrumentation has remained relatively empirical following the engineering approximation presented by Topp et al. (Topp, G.C., Davies, J.L., Anan, A.P., 1980. Electromagnetic determination of soil water content: measurements in coaxial transmission lines. Water Res. Research 16, 574-582.). The refractive index model proposed by Whalley (Whalley, W.R., 1993. Considerations on the use of time domain reflectometry (TDR) for measuring soil water content. J. Soil Sci. 44(1), 1-9.) based on that of Birchak et ...
Linseed oil, also known as flaxseed oil or flax oil, is a colourless to yellowish oil obtained from the dried, ripened seeds of the flax plant (Linum usitatissimum). The oil is obtained by pressing, sometimes followed by solvent extraction. Linseed oil is a drying oil, meaning it can polymerize into a solid form. Due to its polymer-forming properties, linseed oil can be used on its own or blended with combinations of other oils, resins or solvents as an impregnator, drying oil finish or varnish in wood finishing, as a pigment binder in oil paints, as a plasticizer and hardener in putty, and in the manufacture of linoleum. Linseed oil use has declined over the past several decades with increased availability of synthetic alkyd resins-which function similarly but resist yellowing. Linseed oil is an edible oil in demand as a nutritional supplement, as a source of α-Linolenic acid, (an omega-3 fatty acid). In parts of Europe, it is traditionally eaten with potatoes and quark. It is regarded as a ...
