1. Long-term Crop Rotation Diversity Effects on Soil C and N The objective of this study was to evaluate the effects of nitrogen (N) fertilizer level and crop rotation diversity on soil organic carbon (SOC) and N stocks from a 34-yr study located in eastern Nebraska. Seven crop rotations (three continuous cropping systems; two 2-yr crop rotations, and two 4-yr crop rotations) and three N levels were compared. Soil samples were taken to a depth of 60-inches. Differences in SOC stocks were largely confined to the 0 to 3-inch depth with greater SOC (P =... M. Schmer, V. Jin, B. Wienhold, G. Varvel Download paper
2. Impacts of Crop Management on Grain Yield, Grain Quality, Cover Crop Biomass, Residue Cover, and Residual Nitrogen in Dryland Systems Crop production depends on interactions among management practices, yet most studies evaluate the effect of individual practices rather than their interaction. This field experiment was established in 2024 at the Kansas State University Harold and Olympia Lonsinger Sustainability Farm (Osborne County, Kansas) to assess how combinations of common practices affect crop productivity and soil properties in a dryland system Treatments were a factorial combination of crop rotations (continuous...
