Applications: identify under-irrigation, identify over-irrigation and probe placement

Actual evapotranspiration [mm]

  • How much water is used to produce crops each week? Includes crop, cover crop and weed transpiration, as well as evaporation from the soil surface.
  • Hoeveel water word weekliks verbruik vir gewasproduksie? Dit sluit in transpirasie deur gewasse, dekgewasse en onkruid, asook verdamping vanuit die grondoppervlak.
  • You can find more information on using the Actual Evapotranspiration in the March 2015 newsletter.

Evapotranspiration deficit [mm]

  • The difference between an optimal and actual ET for a given area. A high deficit means plants are experiencing water and/or other stresses.
  • Die verskil tussen optimale en werklike totale verdamping van 'n oppervlak. Groot tekorte wys die plante word te min besproei of beleef ander strestoestande.

Biomass Water Use Efficiency [kg/m3]

  • How efficiently are plants using water? This shows how much biomass is produced per unit of water consumed by evapotranspiration.
  • Hoe doeltreffend verbruik plante water? Dit wys hoeveel biomassa geproduseer word per eenheid water verbruik.
  • You can find more information on using the Biomass Water Use Efficiency in the April 2015 newsletter.
