SUB-SURFACE SOIL MOISTURE EFFECT ON ESTABLISHED CROPS

AFWA Subsurface Soil Moisture

Sub-surface soil moisture levels are best used to monitor an established crop. The sub-surface soil moisture is assumed to hold 0-400 mm/m of water depending on the soils water-holding capacity (based on soil texture and soil depth). In general, sub-surface soil moisture levels ranging from:

  • >100-mm indicates an abundance or at least favorable amount of moisture in the subsoil.
  • <100-mm indicates the sub-surface soil moisture storage is short but can still support a well-established crop.
  • <25-mm has very little sub-surface soil moisture and the crop could be severely stressed and reduce yields, especially if it occurs when the top-layer has little or no significant soil moisture and the crop is at a critical stage of growth.
