WebSoil Moisture Seasons: Four soil moisture seasons can be defined by the soil moisture conditions. Recharge: The recharge season is a time when water is added to soil moisture storage (+∆ST). The recharge period occurs when precipitation exceeds potential evapotranspiration but the soil has yet to reach its field capacity. Surplus: WebRecharge: Replacement of water lost during drier periods. Field capacity. The maximum amount of water soil can hold. A water surplus can result in wet soils, high river levels and run-off whereas a deficit leads to dry soil, falling river levels and possibly drought. Management is shown in the example at the end of this topic.
