When precipitation exceeds potential evapotranspiration, there is some refilling of water in dried-up soil pores.

• A. Field capacity
• B. Soil moisture surplus
• C. Wilting point
• D. Soil moisture recharge

Answer: (D)

When precipitation exceeds potential evapotranspiration, there’s more water coming in than is being removed by evaporation and transpiration. That surplus infiltrates the soil and fills the pores that dried out during dry periods. This replenishment of the soil’s stored moisture is soil moisture recharge. It describes restoring the water available in the root zone (and can extend deeper if infiltration continues). Field capacity is about the maximum water the soil can hold after drainage, and the wilting point is the minimal moisture level at which plants can’t extract water. A soil moisture surplus refers to water beyond what plants use, often leading to drainage or runoff. The recharge term specifically captures the process of refilling depleted soil moisture stores when rainfall meets or exceeds demand.
