• Kennedy/Jenks Consultants 1 ' Based on analysis of individual samples from the upper six feet of soil, all soil sample profiles appeared to have similar physical and chemical properties. Soil textures, measured for representative samples of surface and subsurface soils, were all classified as loams. Clay ' contents ranged from approximately 18 to 26 percent in each profile. Sand contents ranged from approximately 39 to 50 percent Saturation percentages ranged from approximately 50 to above 60 percent. ' Surface soil organic matter ranged from approximately 1 to 2 percent, and subsurface soil organic matter ranged from approximately 0.2 to 1 percent. Total Nitrogen concentrations ' ranged from approximately 800 to 1,000 mg/kg in the surface soil and from approximately 100 to 800 mg/kg in the subsurface,with at least 98 percent of the Total Nitrogen coming from Total Kjeldahl Nitrogen (TKN) in all the soil samples. Soil samples were relatively low in nitrate concentration. These in-situ measured nitrate concentrations suggest that these soils may be deficient in nitrate for optimal crop growth. Reclaimed water is expected to have very low nitrate concentrations as well. Soil pH ranged from 6.8 to 8.6, indicating normal soil buffering capacity and slightly alkaline soil conditions characteristic of agricultural soils of the San Joaquin Valley. Concentrations of calcium in the soil are higher than either magnesium or sodium. Calcium concentrations ranged 1 from approximately 3,000 to 5,000 mg/kg throughout the profile with an average of approximately 4,000 mg/kg. Magnesium concentrations ranged from approximately 600 to 1,500 mg/kg. The calcium to magnesium ratios range between approximately 3 to 6, indicating ' satisfactory levels to support agronomic crops. Sodium concentrations ranged from approximately 200 to 500 mg/kg, with no apparent accumulation in surface soil. Exchangeable Sodium Percentages(ESP) range from approximately 6 to 12 percent with an average value of 7 percent, indicating that these soils do not have sodicity issues that would impact agronomic cropping and irrigation. 5.2 Valley View Thoroughbred Farm Soil Investigations Site-specific investigations were not conducted at the Valley View Thoroughbred Farm. However, data collected at the Jepsen Webb Ranch property suggest the soils on that property t . represent typical agricultural soils in the San Joaquin Valley. Irrigation of agronomic and pasture crops with reclaimed water would be appropriate for the soils occurring at the Jepsen Webb Ranch and Valley View Thoroughbred Farm. It is recommended that soils be monitored according to typical agronomic practices to maintain soil quality. 1 Reclamation Report, Page 15 ' Musco Family Olive Company OY goupUtHrinjob102A20104.00�musmorwe%O tEpwls lwoWnrp,"=2tlxretion repodreM01204.a
