As wate moves through the.wit, the nitroc(NO3) that is in <br /> soil Roluticm moles alang with the water. -Vmnonium(NH,') forms of N have a positive Charge <br /> and are held by the negative sites on the clay in the soil;therefore, N11,*.forms of N leach very <br /> little. In sands where there is very,little-clay, Ammonium farms of can leach. Coarse-texturod <br /> sands and came muck Soils rine the only soils where arrinwnium lenhing rutty bt significant. <br /> Onc way to minimizc N lcaching and"denitrification is to mitti mize the time the Nis in the soil <br /> before plant uptake.This cuts on the time when conditibns are favorklc for lcrstio,' Proper <br /> managerneffi of agricultural property significantly reduces the potential nitrate iinpact to groimd <br /> Witter. <br /> The orchard management of the property is w iduccci by the occupant of the residence:. <br /> Our oftict understands that no application vflcrtilizer has been used for the orchard.

The nitrate loading analysis was performed for the full Phase 11 devgloprnent willh air <br /> residence. The result of the analysis indican d that the Nc value was 4.0 mgfL=N. 111c water <br /> quality goal of less than 10 mg, (lac) is recommended for the percolating effluent for the <br /> projccL. The calculated Nc value for the proaczt was foun8 to be wcll'below the maximum <br /> contanhhnate level of 10 mg'L-N'based on the assumptions discussed..A autnn=y of the nitrate <br /> Cloading analysis is presented next. <br /> ° Vrtosh,M.L ,J.
