DSlender coefficient
Correct answer: (C) Soil moisture deficiency — The rainfall needed to saturate the soil is the soil moisture deficiency, so that is the answer.
Explanation
★The rainfall needed to saturate the soil is the soil moisture deficiency, so that is the answer.
★Soil moisture deficiency is the water needed to bring soil to saturation.
★It is the amount required to fill the soil pores not already holding water.
★So the rainfall needed to saturate the soil equals this deficiency.
★It is estimated from rainfall, evapotranspiration and available water capacity.
★So the correct term is soil moisture deficiency.
