1. Long-term Crop Rotation Diversity Effects on Soil C and NThe 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 |
2. Nitrogen Fertilizer Source and Tillage Impacts on Surface and Subsoil C Under Rainfed CornSoil organic carbon (SOC) increases with organic fertilizer and the adoption of no-till. Soil organic C improves the ability of agricultural systems to mitigate and adapt to climate change. This study was conducted to determine the long-term effects of fertilizer type and tillage on profile SOC. The experimental site was a rainfed continuous corn (Zea mays L.) system with fertilizer treatments (150 lbs N a-1) of composted organic waste (OrgF), urea (MinF) and no fertilizer... S. Watts |
