Abstract:
... Rock phosphate (RP) is an important natural source of P for plant nutrition, but the solubility and availability of P from RP is an issue in agricultural production systems. Integrated use of RP with various organic and inorganic byproducts has been reported to increase RP P use efficiency and stability of crop yields. A 2-yr (2010–2011 and 2011–2012) field experiment was conducted to examine the ...

Abstract:
... Corn (Zea mays L.) stover removal for biofuel production is expected to increase in the near future. Previous research suggests stover removal is best suited to continuous corn (CC) cropping systems with reduced tillage. However, grain yields in reduced tillage CC systems in the Upper Midwest can be reduced because of cool soil temperatures restricting early-season growth. Field experiments were c ...

Abstract:
... Corn (Zea mays L.) production systems can benefit from introducing a leguminous winter cover crop into the rotation, especially with regard to increased N availability (i.e., legume N credit); however, it is not known if the full agronomic benefit is realized in the first year of cover crop introduction or if the benefit is cumulative with time. The objective of this study was to determine the app ...
