Soil Moisture describes the wetness or dryness condition of soil top layers above the water table. It considers past conditions (previous 10 days) and future expectations of rainfall, temperature, humidity, and wind speed. For clay soils 27% by volume is on the dry side, ideal moisture would be 30-40% at 4 inches
