Considerations for Fall Fertilizer-Nitrogen Application
October 30, 2019
Fall fertilizer applications offer cost savings and time management benefits, but also may contribute to increased soil nitrate-N leaching. With Nebraska's high soil moisture levels, consider these suggestions when applying nitrogen this fall.
Poultry Manure Reduces Nitrate Loss to Water in Iowa Study
March 6, 2019
Iowa State University researchers concluded from a long-term field study that poultry manure, when applied at a rate to meet crop nitrogen (N) requirements, can reduce nitrate loss and achieve equal or better yields in corn-soybean production systems.
Consequences of Fall-Applied N
November 9, 2018
A fall nitrogen application has a relatively high loss potential and is considered the riskiest N management practice. Consider breaking tradition and splitting your N applications next year to coincide with when your corn most needs more N.
Nebraska Water Center Receives Grant to Research Nitrate Mitigation
June 19, 2018
This project will demonstrate how subsoil injection of an abundant carbon source (recycled sawdust and wood shavings) will establish a biologically active layer for interception and removal of dissolved nitrate after it has left the crop root zone.
