1. Nitrogen benefits when interseeding red clover into continuous corn Information pertaining to the benefits of intereseeding cover crops is lacking. Red clover is a leguminous cover crop that can grow in low radiation environments, is winter hardy for much of the northern USA, and is a low cost weed suppressant that has been shown to provide a nitrogen credit and improve corn yield. While it is clear that red clover is a cover crop that can provide immediate economic benefits in grain-based cropping systems, the potential N credit and the effect of interseedin... H. Francis, M.

2. Nitrogen Application, Biological N Fixation, and N Uptake Previous collaborative research in the Midwest has shown that there is likely little to no need of N for soybean, except under certain conditions (such as when low soil moisture limits N fixation, or when low initial soil nitrate-N limits overall N availability). However, none of the site-years used in this synthesis analysis were on sandy soils. Because sandy soils supply little nitrate-N, the potential impact of N on crop yield is greater in sandy environments than on silt loam soils. Howev... A.M. Walters, M.D. Ruark, J.M. Gaska, C.

3. NITROGEN CREDIT FOR LONG-TERM NO-TILL CROP PRODUCTION IN NORTH DAKOTA Feedback from farmers who had been in no-till crop production for over twenty years indicated that crop production could be maintained at high levels with a reduction in N rate from the universally recommended rates. Nitrogen rate studies in spring wheat/durum, corn and sunflower have confirmed that N rates can be reduced when a farm is under continuous long-term no-till production. A portion of the N credit may be uptake of N by microorganisms, thereby reducing the amount of N exposed to lea... D. Franzen Download paper
4. Use of Biostimulants for Increased Nutrient Uptake in Maize Production Biostimulants are becoming popular in the agricultural market as products to increase growth, health, and/or yield of crop plants. These products differentiate themselves from traditional plant growth regulators as they impact crop growth and development indirectly through mitigation of crop stress and/or greater nutrient availability and uptake. The challenge in working with these products is that there are many types of biostimulants, each with unique mechanisms of action. The objective of ... C.N. Sible, F.E. Below Download paper
