Nitrate concentrations are controlled by both redox conditions and land use

An evaluation of redox status and land use illustrates the interaction of these factors. It appears that redox conditions are a primary control on nitrate concentration. Even the undeveloped area with oxic water has higher concentrations of nitrate than the agricultural area with anoxic water. Within areas of similar redox conditions, land use determines the concentrations of nitrate. The information below is from SIR 2008-5240 (Table 18).
