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 scientific approach to food and nutrition arose with attention to agricultural chemistry in the works of J. G. Wallerius, Humphry Davy, and others. For example, Davy published Elements of Agricultural Chemistry, in a Course of Lectures for the Board of Agriculture (1813) in the United Kingdom which would serve as a foundation for the profession worldwide, going into a fifth edition. Earlier work included that by Carl Wilhelm Scheele who isolated malic acid from apples in 1785. In 1874 the Society of Public Analysts was formed, with the aim of applying analytical methods to the benefit of the public.[3] Its early experiments were based on bread, milk and wine. It was also out of concern for the quality of the food supply, mainly food adulteration and contamination issues that would first stem from intentional contamination to later with chemical food additives by the 1950s. The development of colleges and universities worldwide, most notably in the United States, would expand food chemistry ...

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 ...

Abstract A study on nutritional and microbial analysis of Kunapajala with different storage interval was conducted in the Department of Soil Science & Agricultural Chemistry and Department of Plant Pathology, UBKV, Coochbehar - 736165, West Bengal during March 2019. The motive of this work was to estimate the physicochemical properties, macro, and micronutrient content, and various microbial load of Kunapajala with a different storage time interval. Kunapajala was rich in N, P, K, Ca, Mg, S, Fe, Zn, Cu & Mn and it had a significant beneficial microbial load of Fungi, Actinomycetes, Pseudomonas, solubilising phosphorus bacteria (PSB), Azotobacter, Azospirillum, Rhizobium and Trichoderma. Nutrient content and microbial population change significantly with time in Kunapajala. So, continuous foliar and soil application of Kunapajala from the beginning and up to 40 days after preparation was beneficial to get maximum utilization. It is recommended that Kunapajala can be used as an alternative against ...
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 ...

towns along the Black Sea in 1347 and was spread west along trade routes mainly by Venetian and Genoese sailors. From Pisa, where it had arrived early in 1348, it traveled to Florence and then on to Rome and Bologna; from Venice it moved into southern Germany and Austria; and from Genoa it crossed the Tyrhennian Sea to Barcelona in Spain and Marseilles in France. It continued through the towns of southern France, reaching Paris by early June 1348. From there the contagion spread to England by late June 1348 and the Low Countries by the summer of 1349. Some parts of Europe such as Central Germany and Eastern Europe remained free of the epidemic during the period (1347-1351)--mainly due to their relative isolation. Among the major cities, the Italian town of Milan was less affected as the lord of the city had ordered that the gates of the city be closed to travelers from plague-hit areas ...
Estimating crop nitrogen (N) status with sensors can be useful to adjust fertilizer levels to crop requirements, reducing farmers costs and N losses to the environment. In this study, we evaluated the potential of hyperspectral indices obtained from field data and airborne imagery for developing N fertilizer recommendations in maize (,i,Zea may,/i,s L.). Measurements were taken in a randomized field experiment with six N fertilizer rates ranging from zero to 200 kg∙N∙ha,sup,−1 ,/sup,and four replications on two different dates (before the second fertilizer application and at flowering) in 2012. Readings at ground level were taken with SPAD,sup,®,/sup,, Dualex,sup,®,/sup, and Multiplex,sup,®,/sup, sensors, and airborne data were acquired by flying a hyperspectral and a thermal sensor 300 m over the experimental site. The hyperspectral imagery was used to calculate greenness, chlorophyll and photochemical indices for each plot. The Pearson coefficient was used to quantify the correlation ...
Research has shown that sunflower responds to N, P and K. Nitrogen is usually the most common limiting factor for yield. Nitrogen fertilizer tends to reduce oil percentage of the seed, change the amino acid balance, and increase leaf area of the plant. Yield increases from N fertilizer rates up to 175 lb/acre have been observed, but rates considerably lower than this are usually recommended. Nitrogen recommendations in dryer regions can be made from estimates of nitrate nitrogen in the soil, but in wetter regions, this is not feasible. In the wetter regions of eastern and southern Minnesota and Wisconsin, recommendations are based upon soil organic matter and previous crop history. Recommendations of approximately 18 lb N/acre after fallow or legume sod, 60 lb N/acre after small grain or soybean and 80 to 100 lb N/acre after corn or sugarbeet are common. On higher organic matter soils, amounts should be lowered. Nitrogen can be supplied from mineral or non-mineral sources (manures, legumes, ...

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, ...

Atoderm Préventive je dermo-hranljiva krema, ki od rojstva* naprej omejuje poslabšanje suhosti kože.. Ekskluzivni kompleks Lipigenium™ vsebuje preoblikovalne esencialne maščobne kisline (omega-3 in -6) in biolipide (ceramide), ki so sicer naravno prisotni v koži, pri dojenčkih s suho kožo pa jih primanjkuje.. Biolipidi posnemajo organizacijo kožnih lipidov in se popolnoma združijo s kožo, ob tem pa takoj po nanosu ustvarijo naraven zaščitni film. Za takojšnje in dolgotrajno ohranjanje zdrave kožne bariere biološko spodbujajo produkcijo lipidov in proteinov (filagrina), ki povezujejo korneocite.. Patent Skin Barrier Therapy™ po eni strani omejuje adhezijo in širjenje Staphylococcus aureus-a, po drugi strani pa prodiranje alergenih snovi, ki so glavni povzročitelji poslabšanja suhosti kože.. *Lahko se uporablja pri novorojenčkih, z izjemo nedonošenčkov..
