Evapotranspiration is the biggest cause of water loss on earth We can see rain, but we can’t see the biggest cause of water loss in almost every area on earth: evapotranspiration. Reliable data is lacking on this invisible water loss largely because evapotranspiration is so difficult to measure. Accurate measurements of evapotranspiration can be obtained from advanced hydro-meteorological station including class A Evaporation pan, or from direct measurements of water content changes in the soil. The first type of measurements have as a disadvantage that the representative area of the measurement changes according to wind speed, wind direction and land use. This disadvantage does not count for direct measurements of soil moisture change. The most accurate way of measuring soil moisture content change is by weighing a representative undisturbed soil column with high frequency
