PERCENT SOIL MOISTURE

AFWA Percent Soil Moisture

Percent soil moisture is the available water for the plant divided by the total water holding capacity of the soil profile. It is useful for determining if the soil profile has enough water for crop development.

 
Available water is calculated by the modified Palmer two-layer soil moisture model which accounts for the daily amount of water withdrawn by evapotranspiration and replenished by precipitation. The total water holding capacity for each grid cell was derived from the FAO Digital Soil Map of the World and it is dependent on soil texture and depth of the soil profile. For grid cells with soil depths greater than 1-meter, a maximum soil depth of 1-meter was assumed to approximate the maximum root depth for most plants.
