Soil Chemical Analysis <br /> The capability of soil to receive agricultural waste is classified in three categories: slight,moderate and <br /> severe. Each labeling the soils' capability limitations to the applications of agricultural waste. <br /> The following categories represent specific areas that are commonly used to evaluate soil. <br /> • Available water capacity: <br /> Site conditions of>6.0" are considered to have slight limitations <br /> Site conditions of 3.0" to 6.0"are considered to have moderate limitations <br /> Site conditions of<3.0" are considered to have severe limitations <br /> Soils 195,236 and W are considered to have severe limitations to applications of agricultural waste. It is <br /> recommended to reduce application rates and t=sesp t in <br /> applications for contaminants can flow deep into / <br /> the soil profile due to low retention from the soil. Applications of agricultural wastes improve available <br /> water capacity. <br /> Soils 193 are considered to have moderate limitations to applications of agricultural waste. It is <br /> recommended to reduce application rates for contaminants can flow deep into the soil profile due to low <br /> retention from the soil. Applications of agricultural wastes improve available water capacity <br /> • Dense layer(Bulk density),grams/cc: <br /> All the soils are considered to be<1.7 grams/cc,which classifies them as having a slight limitation to <br /> applications of agricultural wastes. It is recommended that applications of solids are when soil moisture <br /> content is such that the field is in tillable condition. Applications reduce Milk density and minimize <br /> compaction. <br /> • Cation exchange,meq/100g of soil: <br /> Site conditions of>15 are considered to have slight limitations <br /> Site conditions of 5 to 15 are considered to have moderate limitations <br /> Site conditions of<5 are considered to have severe limitations <br /> Soils 182 had test results of 9.4, which is considered to have moderate limitations to applications of <br /> agricultural wastes. It is recommended that this is a relatively low adsorption and exchange of cations and <br /> heavy metals. Soil monitoring of element concentrations through the soil profile is recommended to <br /> evaluate farming practices and application rates of manure solids and nutrient laden water. <br /> Soil#: Cation exchange Limitations <br /> Capacity, mmeq/100g <br /> 182 9.4 Moderate <br /> 237 9.8- 13.8 Moderatg__ <br /> 236 24:5 Slight <br /> Soils off site that have been tested: <br /> Soil#: Cation exchange Limitations <br /> Capacity, mmeq/100g <br /> 102 7.7 Moderate <br /> 220 25.7 Slight <br /> 219 28.6 Slight <br /> L93 28.0 Slight <br /> 241 7.8 Moderate <br /> Western Design/David Avila 2000 14 <br />
