• Soil pH: <br /> Soil pH affects plant nutrient availability, agricultural manure effluent decomposition rates, and <br /> adsorption of heavy metals. (Limitations and recommendations are based on the lowest pH value <br /> of the surface layer). Value of pH is a numerical designation in degrees of acidity of alkalinity, <br /> expressed below: <br /> Below 4.5 Extremely acid 7.4-7.8 Mildly alkaline <br /> 4.5-5.0 Very strongly acid 7.9-8.4 Moderately alkaline <br /> 5.1-5.5 Strongly acid 8.5-9.0 Strongly alkaline <br /> 5.6-6.0 Moderately acid 9.1- Very strongly alkaline <br /> 6.1-6.5 Slightly acid <br /> 6.6-7.3 Neutral <br /> Site conditions of >6.5 are considered to have slight limitations. <br /> Site conditions of 3.5 - 6.5 are considered to have moderate limitations. <br /> Site conditions of <3.5 are considered to have severe limitation S.4 <br /> Refer to page 30 for Endnotes and Reference Sources <br /> Soil Suitability Study <br /> Property Name and Address: Frank Faria Dairy,Inc., 12182 S.Robinson Road, Escalon,CA 95320 <br /> Page 19 <br /> Western Design/David Avila 2001 <br />
