6. <br /> ` September 30,2002 <br /> Job Number:LG02-335 <br /> Page 10 <br /> samples were submitted to Precision Enviro-Tech Analytical Laboratory for nitrate analysis on <br /> September 25, 2002. The result of the samples are presented in the following table. <br /> Table 6. <br /> Nitrate Concentration of Soil in Almond Orchard. <br /> =Side <br /> Date Collected Nitrate ppm(mg/kg) <br /> : 9-25-02 ND <br /> e: 9-25-02 75 <br /> ND is non-detectable. <br /> r <br /> The soil samples obtained from the orchards indicate the nitrate concentration of the soil <br /> ranges from non detectable to 75 parts per million(ppm). The west side soil sample was found to <br /> be have a 75 ppm concentration of nitrate probably indicating residual nitrogen from a recent <br /> fertilizer application. The east side sample was non detectable. Generally,no conclusions can be <br /> ` drawn regarding proper or improper care of the orchard. The nitrate level appears to be in a <br /> normal typical range for cultivated orchard soil. <br /> A visual inspection of the almond orchard indicates the orchard appears to be healthy and <br /> cared for. For the purposes of this report, our office is assuming that the fertilizer applied is <br /> applied in a correct manner. Our assumption is that leaching of nitrogen is minimal. There is no <br /> records or knowledge regarding the past or present fertilization practices for the orchard. The <br /> operator of the orchard was unavailable for an interview. <br /> Nitrates from Chicken Manure <br /> Chicken manure is a potential source of nitrogen. Chicken manure is used as a soil <br /> fertilizer and contains organic nitrogen,NO3, and NH4. Chicken manure is a marketable waste <br /> 4 product and is used as a soil amendment for gardens and landscape. <br /> The potential manure waste generating from the proposed12 00� 0 egg laying chickens is 1,2� <br /> described in a manure plan prepared for the project. The manure plan indicates the wastelv <br /> b. products will be sold and removed off the site by customers or haulers. The manure will not be .'` <br /> applied to land on the site. The two manure ponds that were previously used for ma—e isposal e, s� <br /> r are planned to be abandoned as part of the proposed project.
