Nitrate Concentrations in the Unsaturated Zone Beneath Irrigated Fields in Southern California
1973
Pratt, P. F. | Adriano, D. C.
Nitrate concentrations in the drainage water of the unsaturated zone beneath the soil-root zone were predicted from data for N inputs, N removal in harvested crops, and the drainage volume. Ratios of these predicted values to measured values were related to the volatilization losses or unaccounted-for inputs expressed as a fraction of the excess N defined as the N input minus N removal in harvested crops. Volatilization losses or unaccounted-for inputs were calculated as known inputs minus removal in harvested crops minus that removed from the soil-root system by leaching.
