The results of the calculations for the site soils are presented below: I r Available Water f Jacktone clay 8.41" Madera sandy loam 6.39" r Manteca fine sandy loam 8.08" Stockton clay 9.04" Site conditions of>6.0" are considered to have slight limitations FrSite conditions of 3.0" to 6.0" are considered to have moderate limitations Site conditions of<3.0" are considered to have severe limitations All site soils have slight limitations. The volume of liquid agricultural waste application should not exceed the available water capacity of the root zone or-the soil moisture deficit at the time of application. Low rates and frequent applications of liquid agricultural wastes on soil that has low available water capacity or during periods of high soil moisture deficit can reduce potential for -ground water contamination. Fe' Rooting Depth The depth of soil from which a crop can extract water is the effective crop rooting depth. This depth will vary with the stage of crop growth. Rooting depth may be restricted to a depth ' considerably less than the normal root depth by soil limitations (i.e., hardpan, high water table, and so forth). Irrigation design rooting depths for several mature irrigated crops, grown on deep, permeable well-drained soil, are given in Table 2 (Appendix C) Limitations for application of agricultural wastes are slight if bedrock or a cemented pan is at a F . depth of more than 40 inches, moderate if it is at a depth of 20 to 40 inches, and severe at'a depth of less than 20 .inches. i Based upon the MRCS soil data, the Jackten,e. Madera, and Manteca.soils have moderate; limitations because have a cemented pan between approximately 20"-40" and the Stockton soils F. have a slight limitations because the cemented gan is between 40"-60". Limitations for.application of agricultural wastes are slight if the water table is at a depth of more than 4 feet, moderate at a depth of 2 to 4 feet, and severe if it is at a depth of less than 2 feet. F4 Depth and type of water table, time of year, and duration data should be collected if agricultural wastes are to be applied to soils suspected of having a water table within 4 feet.of the soil surface. FThe depth to high water table for the site soils is greater than 5 ft. and it can be concluded that the limitations for application of agricultural waste are slight.
