University of Nebraska-Lincoln Extension: Historical Materials

Nitrate-nitrogen in groundwater is a major public concern. Agriculture is often targeted as the primary source; however, crop producers are reluctant to reduce the amount of nitrogen they apply in fear of reducing crop yields and profits. Soil testing for nitrate-nitrogen is being promoted as a way to fine-tune or improve nitrogen management, but adoption by producers has been slow. This publication explains how to conduct a field demonstration using scientifically acceptable methods that are practical for on-farm use.
