Deskripsi
Deep drilling of soil profiles in the Chino-Corona dairy area, which has an estimated average NO-3 concentration of about 315 ppm (70 ppm NO3-N) in drainage water underneath croplands and pastures. Predictions for the NO-3 concentration in the drainage water in the unsaturated zone for this disposal rate agree with this determined value. The disposal rate should be lowered to about three to four cows per disposal acre to have an acceptable NO-3 load in the drainage water.
