| Contents Notes |
Because of a tremendous increase in the concern for nitrate (NOå3) in surface and ground waters, the study of NOå3 leaching has become very important. The present investigation was undertaken to determine the potential contribution of fertilizer N use on citrus and row crops to the NOå3 in ground waters in the Santa Ana River Basin of Southern California where a deep unsaturated zone exists between the soil profile or crop-root zone and the water table or saturated zone. The objectives were to relate NOå3 concentrations in the unsaturated zone to N inputs, N removal by harvested crops and the volume of drainage water, to obtain some estimates of transit times for drainage water through the unsaturated zone, to estimate denitrification losses on a field basis, and to assess the probable effects of present fertilizer N recommendations on NOå3 in ground waters. |
