DOI: 10.1002/jeq2.20342
Abstract: Cover crops can reduce nitrate leaching after cash crop harvest. Despite widespread cover crop implementation there has been a limited impact on water quality in the Chesapeake Bay watershed. We hypothesize that typical timing for… read more here.

DOI: 10.1002/jeq2.20385
Abstract: Inefficient nitrogen (N) fertilization and irrigation have led to unhealthy nitrate levels in groundwater bodies of agricultural areas in California. Simultaneously, high commodity prices and drought have encouraged perennial crop growers to turnover less productive… read more here.

DOI: 10.1007/s10661-021-09605-x
Abstract: Deterioration of groundwater quality due to nitrate loss from intensive agricultural systems can only be mitigated if methods for in-situ monitoring of nitrate leaching under active farmers’ fields are available. In this study, three methods… read more here.

DOI: 10.1007/s11104-017-3494-4
Abstract: BackgroundNitrate leaching is a primary pathway of nitrogen loss from agricultural systems, and is affected by both tillage and cropped species. However, there is little information on conservation systems without nitrogen fertilization.MethodsNitrate leaching was assessed… read more here.
