This cuts down on the time when conditions are favorable for losses.' <br /> According to Robert Weststeyn, Fransis, Groen(PCA CCA) of the Ripon Farm Service <br /> provides agricultural consulting regarding the fertilization, irrigation, and testing of the orchard. <br /> Based on these recommendations, Mr. Weststeyn applies approximately 100-units of nitrogen to <br /> each acre each year. Each unit of nitrogen is about 300-pounds of nitrogen. The fertilizer is <br /> applied in three(3)broadcasts (applications) in a pellet form to maximize uptake in the root zone <br /> and to minimize leaching. Irrigation is applied approximately eight(8) times per year, <br /> approximately three(3) inches per application. <br /> Because an agricultural consultant advises Mr. Weststeyn, an assumption was made that <br /> the irrigation, fertilization, and uptake of nitrogen by the almond orchard are considered in <br /> balance(eg: irrigation and nutrients are being consumed by the orchard). <br /> So uK <br /> The following table is a summary of the Nitrate Loading Analysis (see Plates 9 through <br /> 16)which considers nitrate concentrations and quantities from septic waste water and rainfall <br /> sources. The analysis was performed using a denitrification factor of 10% and the Hantzshe& <br /> Finnemore equation for each size of parcel. The analysis also assumed that a second dwelling <br /> unit consisting of 3 bedrooms may be built on the property in the future. The following table is a <br /> summary of this analysis. <br /> Table 7. <br /> Summary of Nitrate Mass Balance Analysis. <br /> Parcel Size Parcel No. (Plate No.) Result: Average Quantity of <br /> _ Nitrate Concentration Effluent <br /> of Percolating Water <br /> 2.17 acres(4-bdrm res) Parcel 7(Plate 9) 8.28 mg/L-N 350 gpd <br /> 2.17 acres(4-bdrm res+SDU) Parcel 7(Plate 10) 12.26 mg/L-N 630 gpd <br /> 2.48 acre(4-bdrm res) Parcels I &6(Plate l 1) 7.50 mg/L-N 350 gpd <br /> 2.48 acre(4-bdrm res+ SDU) Parcels 1 &6(Plate 12) 11.29 mg/L-N 630 gpd ' <br /> 2.50 acre(4-bdrm res) Parcels 2,3,4,5 (Plate 13) 7.46 mg/L-N 350 gpd <br /> 9 Vitosh,M.
