New Research Shows When Nebraska’s Groundwater Supply Recharges

May 28, 2020
When it rains, and even when it pours and floods like it did in Nebraska in late 2018 and through much of 2019, the precipitation that hits the surface doesn’t always factor in to recharging the state’s vast and vital groundwater supply. So when does it most often happen?

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.
