The nitrate loading analysis will assume 45 mg/L-N for the <br /> concentration orthe domestic waste water for the site. <br /> Nitrate from Agriculture <br /> Leaching losses of nitrate fertilizer occur when soils have more incoming water(rain or <br /> irrigation) than the soil can hold. As water moves through the soil, the nitrate(NOA that is in <br /> soil solution moves along with the water. Ammonium(NH4') forms of N have a positive charge <br /> and are held by the negative sites on the clay in the soil; therefore,NH4'forms of N leach very <br /> little. In sands where there is very little clay, ammonium forms of N can leach. Coarse-textured <br /> sands and some muck soils are the only soils where ammonium leaching may be significant. <br /> One way to minimize N leaching and denitrification is to minimize the time the N is in the soil <br /> before plant uptake. This cuts down on the time when conditions are favorable for losses.9 <br /> According to Marc Fisher, Elton Bruns, PCA, CCA, (Pest Control Advisor, Certified <br /> Crop Advisor)provides agricultural consulting regarding the fertilization, irrigation, and <br /> moisture testing of the orchard soils for Fisher Farm I-e.s' les and soil nutrients are <br /> regularly tested adjustments of fertilizers and irrigatio e mace frquently.
