  • carbon
  • Soil carbon (C) is the most important variable in sustaining annual and perennial cropping systems both in terms of increasing crop productivity and enhancing soil health. (sare.org)
  • Here, we examined the role that plant diversity has on root production and soil carbon dynamics in annual and perennial crops in a controlled cropping systems experiment. (sare.org)
  • Midwestern soils have lost between 30 and 50% of historic carbon (C) levels, negatively impacting soil health within agroecosystems (Lal, 2004). (sare.org)
  • A potential tool to reduce nutrient availability and aboveground productivity without destroying the perennial vegetation is carbon (C) addition. (epfl.ch)
  • Perennial crops also show promise in root-based carbon sequestration. (wikipedia.org)
  • For example, Paustian and colleagues recently published a paper in Nature titled "Climate-Smart Soils" that compares different landscape management approaches for increasing soil carbon sequestration. (wikipedia.org)
  • By providing year-round soil coverage and exceptionally large belowground carbon inputs from roots, farmers growing Kernza® and other perennial grains will: sequester more carbon reduce nitrogen and phosphorus contamination of freshwater and marine ecosystems, and reduce weed competition, minimizing tillage and herbicide applications. (wikipedia.org)
  • grass
  • The exotic annual grass Bromus tectorum has replaced thousands of hectares of native perennial vegetation in semi-arid ecosystems of the western United States. (springer.com)
  • Litterbags had greater mass loss and N mineralization when buried in Bromus stands than in Artemisia stands, indicating the soil environment under the annual grass promotes decomposition. (springer.com)
  • An approach that could be adopted by farmers to significantly build soil C is increasing crop diversity through planting cover crops, incorporating crop rotations, and by planting perennial mixed grass systems in place of fallow land. (sare.org)
  • The key to amending your soil is organic matter such as straw, hay, leaves, manure or grass clippings. (diynetwork.com)
  • Perennial weeds with bulbils, such as lesser celandine and oxalis, or with persistent underground stems such as couch grass (Agropyron repens) or creeping buttercup (Ranunculus repens) store reserves of food, and are thus able to grow faster and with more vigour than their annual counterparts. (wikipedia.org)
  • plant
  • It is obvious that a plant can grow well in the soil with rich nutrition. (greencrudeproduction.com)
  • Think about taller perennial flower if you plant it around big building. (greencrudeproduction.com)
  • Step by step instructions on how to plant your bare root or potted perennials when they arrive. (americanmeadows.com)
  • A beautiful bright blue perennial wildflower plant found growing on roadsides and waste ground across Britain. (wildflower.co.uk)
  • After 3 years, soil pH, ammonium, and plant-available phosphorus were not altered by sawdust application, and nitrate concentrations were marginally higher in treatment plots. (epfl.ch)
  • Put an end cap on each spike, and pound it into the soil around the drip line (the outer edge of the leafy top part of the plant). (diynetwork.com)
  • If you see a plant has heaved, push it back into the soil as soon as possible and give it some extra mulch to keep it shaded and prevent the soil from thawing. (gardenguides.com)
  • A perennial plant or simply perennial is a plant that lives for more than two years. (wikipedia.org)
  • However, depending on the rigors of local climate, a plant that is a perennial in its native habitat, or in a milder garden, may be treated by a gardener as an annual and planted out every year, from seed, from cuttings or from divisions. (wikipedia.org)
  • Penstemon palmeri is a drought-tolerant perennial plant, preferring well draining drier soils. (wikipedia.org)
  • Cascadian Farm has agreed to purchase an initial amount of the perennial grain, which is driving farmers to plant on commercial-scale fields versus the test sized plots currently being grown. (wikipedia.org)
  • The plant has small, rounded tubers which are buried deep in the ground and which enable it to survive being covered with snow for several months and withstand temperatures down to −20 °C (−4 °F). Tropaeolum polyphyllum needs full sun and neutral or slightly acid, well drained soil. (wikipedia.org)
  • While these structures are annual in nature, the plant itself may be annual, biannual, or perennial. (wikipedia.org)
  • mineralization
  • As determined by spring isotope-dilution assays, gross mineralization and nitrification rates were higher in Bromus -dominated than Artemisia -dominated soils, but gross rates of NH 4 + and NO 3 − consumption were also higher. (springer.com)
  • An in situ net mineralization assay conducted in autumn indicated that germinating Bromus seedlings are a strong sink for soil NO 3 − , and that net nitrification is inherently low in soils under Artemisia and Elymus . (springer.com)
  • compost
  • Bury vegetable and fruit parts, coffee grounds and egg shells in trenches or holes in loose garden soil, or stuff them into compost piles. (baltimoresun.com)
  • They will enrich the soil and compost as they decompose. (baltimoresun.com)
  • Recycle fall leaves into compost, a soil amendment or a nutritious topdressing for the lawn. (njtoday.net)
  • Transplanted crops raised in sterile soil or potting compost gain a head start over germinating weeds. (wikipedia.org)
  • organic
  • To do this we sampled 52 farm fields in Michigan and compared the total soil organic matter test to the active C test and determined which test better reflected farmer perceptions of soil organic matter. (sare.org)
  • Our on-farm work demonstrates that the total soil organic matter test is insufficient at determining differences in soil C between farmer-described Best vs. Worst fields. (sare.org)
  • Such reductions in soil organic matter have also contributed to enhanced CO 2 emissions from agriculture. (sare.org)
  • Organic amendments will help correct soil deficiencies in a new garden plot. (diynetwork.com)
  • farmers
  • Currently, soil tests available to farmers only represent the total C pool, which may not fully reflect soil health. (sare.org)
  • periods
  • In many parts of the world, seasonality is expressed as wet and dry periods rather than warm and cold periods, and deciduous perennials lose their leaves in the dry season. (wikipedia.org)
  • structures
  • Perennials typically grow structures that allow them to adapt to living from one year to the next through a form of vegetative reproduction rather than seeding. (wikipedia.org)
  • decomposition
  • Removal of inhibition to germination of perennial ryegrass was linked to the decomposition of nC10 and nC11 hydrocarbons and took from 11 to 30 days at diesel additions up to 50 mg/g depending on the soil. (aber.ac.uk)
