It is widely accepted that yields decline when corn ( Zea mays L.) grown continuously vs. in rotation with soybean [ Glycine max (L.) Merr.], although causes for the yield reduction are unclear. The primary objective of this study was to elucidate source(s) continuous penalty (CCYP). experiment conducted from 2005 2010 east‐central Illinois beginning third‐year (CC) or a soybean–corn (SC) at six N fertilizer rates. Averaged across all years, agronomic optimum rate CC 8.84 Mg ha −1 and SC...
The need to intensify agricultural production due a growing human population requires yield gaps be closed. In 2009 and 2010, five management factors were assessed for their individual cumulative contributions reducing the corn ( Zea mays L.) gap components in corn–soybean [ Glycine max (L.) Merr.] rotation. Five (plant population, transgenic insect resistance, fungicide containing strobilurin, P–S–Zn fertility, N fertility) evaluated. An incomplete factorial design with these resulted 12...
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 credit); however, it is not known if full agronomic realized in first year of introduction or cumulative time. The objective this study was determine apparent red clover Trifolium pratense credit corn conventional system where introduced for time compared three agricultural that had 14‐yr history using crops....
Abstract Cover crops have many environmental benefits, including nutrient sequestering, soil health improvements, carbon dioxide removal, and biodiversity increases. Yet, farmers often do not receive enough benefits to warrant planting cover crops, particularly when they no prior experience with managing crops. Therefore, public policies supporting crop use may be justified because of the positive externalities are greater than social cost programs. Current Federal programs provide funding...
Abstract Following the unprecedented oil drilling presently occurring in western North Dakota, thousands of kilometers roads must be reclaimed to an acceptable post‐extraction condition. This study assessed soil biological and plant communities nine decommissioned during three periods between 1983 2002 Little Missouri National Grasslands Dakota. We hypothesized that time‐since‐reclamation would positively affect and, consequently, success reclamation at older sites. To assess this...
Abstract Associations between nitrogen (N) management and losses with soil health indicators (SHI) are widely presumed but relatively untested. An on‐farm experiment conducted in central Illinois was to test potential relationships of SHI agroecosystem outcomes maize ( Zea mays L.) yield N under bounding N‐fertilization rates 168 252 kg/ha. Chemical n = 19), physical 11), biological 14) were measured at 24 locations within a 30 ha field five timepoints (V3, V10, RT, R6, post‐harvest). Yields...
