  • Comparison of runoff quantity and quality under annual cropping and forages

    Conversion from annual cropping to perennial forages may be a beneficial management practice (BMP) to reduce runoff quantity and improve surface water quality. Runoff variables were determined in two 30 ha producer's fields over 4 years (2004–2007) using a rainfall simulator. Field 1 was cropped to barley (Hordeum vulgare L.) in 2004 and then an alfalfa (Medicago sp.) and grass mix used for ...

  • 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. ...

  • Quantifying straw removal through baling and measuring the long-term impact on soil quality and wheat production

    Crop residues are considered the feedstock of choice for the production of ethanol, but removing crop residues may negatively impact soil productivity. The objectives were to quantify the proportion of total aboveground crop residues removed through baling and to evaluate the effects of 50 yr of straw removal with baling on soil quality and wheat (Triticum aestivum L.) production. The first study ...

  • Impact of Agri-environment measures

    The application of agri-environment contracts concerning 1 farmer in every 7 and delivering environmental services over 20% of European farmland, marks a very significant step towards sustainability. The target set in the 5th Environmental Action Programme of 15% coverage by 2000 has thus already been exceeded. The requirement on Member States to apply the regulation throughout their territories ...

  • Can water use efficiency be modeled well enough to impact crop management?

    Crop water use efficiency (WUE, yield per unit of water use) is key for agricultural production with limited water resources. Policymakers and water resource managers working at all scales need to address the multitudinous scenarios in which cropping systems and amounts, timing and methods of irrigation, and fertilizer applications may be changed to improve WUE while meeting yield and harvest ...

  • Rotary batch blender mixes biological products that boost farm crops

    Agriculture has never been more challenging and fertility efficiency tools, such as inoculants, more important. Modern farmers rely on technology and production practices to significantly increase the yield of their food crops. Biological products like inoculants are a vital part of that strategy. Novozymes Biologicals is an industry leader in developing and manufacturing inoculants, which are a ...

  • Harvesting Corn Stover and Soil Quality

    Corn stover, left in fields after corn grain harvest, has been identified as a potential feedstock to help supply biofuel needed to offset a portion of the 14 million barrels of oils consumed daily by the U.S. transportation sector. It was projected to supply 256 million tons of the 1.4 billion tons of biomass (232 million Mg out of 1.3 billion Mg) estimated to be available each year. Corn stover ...

  • 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 ...

  • Mushroom yield optimisation using carbon dioxide Measurement

    Compost “quality” depends on many characteristics including dry matter content, moisture content, colour and structure. Compost of good quality can be expected to have a potential for a high yield of mushrooms and, conversely, one of poor quality for a low yield. Even though mushroom growers can often recognise differences in compost quality, prediction of the subsequent yield of mushrooms is ...

  • Stevens Water and US Farm Bill Helps Farmers Optimize Crop Irrigation & Fertilization

    Agriculture is a major element for survival of the human race and of the economic system. 42 percent of the world’s laborers are employed in agriculture, making it by far the most common occupation. With agriculture using approximately 60 percent of available fresh water withdrawals, concerns continue to grow over farmers implementing water conservation practices. Also, increasing contamination ...

  • Simulated effects of Nitrogen management and soil microbes on soil Ntrogen balance and crop production

    Searching for environmentally friendly N management practices in the midwestern United States is an ongoing task in the agricultural community. Many practices have shown promise in reducing N in tile drainage that may contribute to hypoxia in the Gulf of Mexico. In this study, an agricultural system in central Iowa, managed using a corn (Zea mays L.)–soybean [Glycine max (L.) Merr.] rotation from ...

  • Effects of estimating soil hydraulic properties and root growth factor on soil water balance and crop production

    Accurate simulation of plant growth depends not only on plant parameters, but also on soil parameters. Although there is uncertainty in measured soil parameters and root distributions, their effects on simulated plant growth have been much less studied. This study evaluates the simulated responses of six crops, wheat (Triticum aestivum L.), maize (Zea mays L.), barley (Hordeum vulgare L.), ...

  • Production of dryland barley for human food: quality and agronomic performance

    Grain β-glucan content is the most important attribute for barley (Hordeum vulgare L.) varieties destined for the human food market. This trait is important because of the blood glucose and cholesterol-reducing properties of β-glucans. High levels of grain protein content, test weight, and seed size and endosperm color may also add value. Seed yield potential, in part, determines the ...

  • Modelling Common Agricultural Policy–Water Framework Directive interactions and cost-effectiveness of measures to reduce nitrogen pollution

    Selecting cost-effective measures to regulate agricultural water pollution to conform to the Water Framework Directive presents multiple challenges. A bio-economic modelling approach is presented that has been used to explore the water quality and economic effects of the 2003 Common Agricultural Policy Reform and to assess the cost-effectiveness of input quotas and emission standards against ...

  • Methane flux in cropland and adjacent riparian buffers with different vegetation covers

    Received for publication September 12, 2008. While water quality functions of conservation buffers established adjacent to cropped fields have been widely documented, the relative contribution of these re-established perennial plant systems to greenhouse gases has not been completely documented. In the case of methane (CH4), these systems have the potential to serve as sinks of CH4 or may provide ...

  • 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 ...
