  • Integrating winter annual forages into a no-till corn silage system

    The benefits of cover crops within crop rotations are well documented, but information is limited on using cover crops for forage within midwestern United States cropping systems, especially under no-tillage management. Our objective was to evaluate plant, animal, and soil responses when integrating winter cover crop forages into no-till corn (Zea mays L.) silage production. Three cover crop ...

  • Zone tillage depth affects yield and economics of corn silage production

    Increasing numbers of dairies in northeastern United States are classified as confined animal feeding operations (CAFOs). Many dairy farmers in New York (NY) abandoned conventional and adopted zone tillage (ZT) in 4-yr corn (Zea mays L.) silage-alfalfa (Medicago sativa L.) rotations on highly erodible land to comply with NY CAFO plans. Farmers now question optimum ZT depth because of increased ...

  • Dairy manure compost effects on corn silage production and soil properties

    Accumulation of dairy manure compost has created a need to identify alternative uses for this plant nutrient source. This field study determined compost effects on corn (Zea mays L.) silage production, nutritive value, and soil characteristics for three growing seasons following incorporation of dairy manure compost at 0, 35, 70, and 105 Mg dry matter (DM) ha–1. Yields from subplots receiving ...

  • Dairy manure compost quality effects on corn silage and soil properties

    Soil nutrients in dairy manure composts vary depending on the original manure or other additives, with consequent effects on crop production. An experiment addressing the effects of single applications of dairy compost of high quality (HQC) or low quality (LQC) at the incorporation rates of 0, 45, and 90 Mg ha-1 on corn (Zea mays L.) silage yields, forage quality, and soil nutrients was conducted ...

  • Effect of nitrogen application on yield and quality of silage corn after forage legume-grass

    Decomposition of forage legume-grass (FLG) sods after turnover will supply N to the next corn (Zea mays L.) crop. For optimum economic grain production typically a starter N application is sufficient. However, the impact of eliminating sidedress N on yield and quality of silage corn in the year after sod turnover (FYC) is not well documented and little is known about the effects of timing of sod ...

  • Cover crop and liquid manure effects on soil quality indicators in a corn silage system

    Due to a lack of surface residue and organic matter inputs, continuous corn (Zea mays L.) silage production is one of the most demanding cropping systems imposed on our soil resources. In this study, our objective was to determine if using cover/companion crops and/or applying low-solids liquid dairy manure could improve physical, chemical, and biological soil properties and overall soil quality. ...

  • Impact of defoliation on corn forage quality

    Hail damage can be a serious problem on corn (Zea mays L.) grown for silage. The value of corn grown for silage is a function of both the yield and quality of the forage produced. An improved understanding of the effects of defoliation on forage quality would improve the ability of agronomists, farmers, and crop insurance adjusters to assess the economic impact of hail damage to corn harvested ...

  • Seed-applied insecticides inconsistently affect corn forage in continuous corn

    Western corn rootworm (Diabrotica virgifera virgifera Le Conte) is the major insect pest in the corn phase of a corn (Zea mays L.) silage–perennial forage rotation. Dairy producers may prefer seed-applied instead of soil-applied insecticides for rootworm control because of ease of use and additional control of some other soil insect pests. The objective of the 2-yr NY field study was to evaluate ...

  • Dietary forage impacts on dairy slurry nitrogen availability to corn

    Precise feeding of protein and mineral supplement can maintain high levels of milk production and reduce nutrient excretion in dairy manure and losses to the environment. No information is available on the impacts of feeding different silages to dairy cattle (Bos taurus) on manure N cycling in soils. Slurry from dairy cattle fed rations containing alfalfa (Medicago sativa L.; ALF), red clover ...

  • How is Ethanol Produced?

    What is ethanol? Ethanol is an alternative fuel made from corn, sugarcane, wheat, and other agricultural products, and is produced by the fermentation of carbohydrates such as sugar, starch, and cellulose. Ethanol Feedstocks All plants contain sugars that can be fermented to make ethanol in a process called biochemical conversion. Plant material can also ...

  • A small plant with great success - case study

    The farm-based biogas plant operated by the Wienken family in Augustenfeld (near Löningen) is the first plant of its size built by bwe. Originally, the farm's operator had planned to install a straw heating element. However, since the input materials are available on the farm itself in their entirety, the decision to implement a biogas plant designed by bwe was obvious. One decisive aspect ...

  • Performance of a dispersion model to estimate methane loss from cattle in pens

    Received for publication December 29, 2008. Accurate measurements of enteric methane (CH4) emissions from cattle (Bos taurus) are necessary to improve emission coefficients used in national emissions inventories, and to evaluate mitigation strategies. Our study was conducted to evaluate a novel approach that allowed near continuous CH4 measurement from beef cattle confined in pens. The backward ...

  • Long-term Polyacrylamide formulation effects on soil erosion, water infiltration, and yields of furrow-irrigated crops

    Two formulations of water-soluble anionic polyacrylamide (WSPAM) are used in agriculture to reduce erosion and manage infiltration in furrow irrigations, although few if any reports have compared their effectiveness. A control and two WSPAMs, a granular form and the inverse emulsion, or oil-based liquid form, were applied to irrigation water supplied to furrows formed in a silt loam soil with ...

    ANAEROBIC DIGESTER ON UNIVERSITY CAMPUS The University of Guelph’s Ridgetown Campus, part of the Ontario Agriculture College (OAC), received an investment of more than US$2.6 million for construction of an anaerobic digester through the Federal Development Agency for Southern Ontario. OAC, with its Center for Agricultural Renewable Energy and Sustainability, views the digester as “a ...

  • Family farms can be competitive by focusing on conservation and stewardship

    While the U.S. Department of Agriculture (USDA) reports a 40 percent decline in U.S. cropland soil erosion rates from 1982 to 2007, recent trends appear to challenge this progress. Record prices for corn and soybeans have diverted acres out of conservation programs and encouraged intensive production on a wide scale. Tree lines are cleared and wet areas drained, turning 120-acre farms into ...

  • Unlocking the potential of poultry manure

    The poultry industry is one of the largest and fastest-growing agro-based industries in the world. At the same time, the growth brings along a number of environmental problems. One of the major environmental problems is the accumulation of large amounts of wastes, e.g. manure. In order to mitigate these problems new economically sustainable technologies are needed. Manure has often been ...
