Phosphates: <br /> Total phosphate in the soils appears to be directly related to the clay content of the sediments, <br /> increasing in sediments containing a higher clay content. The levels present in the boring are similar to <br /> what would be anticipated as present in sediments of this type. Consequently,any contribution from <br /> animal wastes appears to be minimal. <br /> Total Dissolved Solids: <br /> Total Dissolved Solids in MDS-1 are highest in the uppermost clayey sand sequence. The highest <br /> soluble component is present at a depth of ten feet below surface and is lowest in the silty clay sequence. <br /> The presence of a caliche bed in MDS-2 and the depth distribution of soluble salts suggest that the <br /> distribution of this component is primarily due to concentration of naturally occurring salts by capillary <br /> action and not by leaching from agricultural sources. <br /> wastes. In general,moderate limitations or suitability ratings require less management than do the <br /> severe ratings. <br /> Water holding capacity-Moderate: Varies to the depth of 5 feet. In general, it is safe to calculate that <br /> the water holding capacity is>3"which is considered to be moderate. <br /> Depth to hardpan-Moderate: 20 plus inches to hardpan is considered to be moderate for application <br /> of agricultural wastes. Over application of waste can cause the accumulation of wastes and mineralization <br /> by products above the hardpan. When this accumulation occurs over fractured hardpan,the potential for <br /> ground water and aquifer contamination is high. Although there is this potential of contamination,the soil <br /> boring sample tests indicate that the surface water has not penetrated beyond the 35' depth,even with the <br /> constant head pressure at the lagoon. <br /> Depth to high water table-Slight: <br /> A depth of more than 4 feet is considered to be slight The water table of the area is at approximately <br /> 85'. The fluctuation of the water table is insignificant at that depth. Although the water table has a <br /> historically risen slightly in the South San Joaquin Irrigation District in past years. Escalon is in the South <br /> San Joaquin Irrigation District. <br /> Flooding-Slight: <br /> The area is in flood zone C,no flooding. <br /> Rock Fractions-Slight: 0 <br /> Soils having less than 0.1 percent of surface covered with stones and boulders are class I,or slight. <br /> Intake Rate-Moderate: Group D <br /> The predominate soil#193 is classified in the hydrologic group D. Group D soils have a slow intake <br /> potential,high runoff potential, and generally have moderate limitations for the applications of <br /> agricultural wastes. Incorporating agricultural wastes applied to hydrologic group D soils helps to prevent <br /> the removal and transport of wastes by runoff and water erosion and can reduce the potential for surface <br /> water contamination. <br /> Permeability Rate: 1 1/2"per hour. <br /> Permeability Rate for application of solids- Slight <br /> Permeability Rate for application of liquids- Slight <br /> Soil#193 is considered to have an intake rate of 1 1/2"per hour. This rate is considered to be slight in <br /> both the applications of solid and liquid agricultural waste. Agricultural waste can be applied to soils that <br /> have only slight limitations because of permeability. Agricultural wastes applied to soils that have <br /> permeability of less than 0.2 inch per hour should be incorporated(solids)or injected(liquids)into the <br /> soil to reduce potential surface water contamination from erosion and runoff. <br /> Analysis of the two samples from the uppermost portion of the clayey silt layer(25 &30 feet bgs)show <br /> an increasing clay content and decreasing permeability with depth. Clay content increased from 16.4 to <br /> 29.1 percent and permeability decreased from 1.2X105 to 1.2X 10-6 cm/sec. <br /> Bulk density-Slight: 1.38 gram/cm3 <br /> Soils with a bulk density of 1.7 grams/cm3 or less have slight limitations for application of agricultural <br /> wastes. <br /> 7 <br />
