Satellites measures the crop. For the moisture balance Fieldlook looks to evaporation. Not the soil related elements but directly at the point where it's happening: inside the plant! Evaporation is directly related to growth. The combination of the evaporation parameters on Fieldlook provides a correct view of the moisture balance and indicates possible shortages.

Evaporation
The actual evaporation of the plant. Direct in millimeters of water over a period of one week. Estimates based on a general reference evaporation is no longer necessary. Fieldlook measures the actual evaporation.

Evaporation shortage
Because so much of the plant is measured at Fieldlook, it is possible to calculate from meteorological data whether your crops suffer a shortage of evaporation. A lack of evaporation means less growth than when sufficient water would have been provided. The evaporation shortage is the number of millimeters of water per week your crop missed to achieve the maximum evaporation (and growth).

Surplus precipitation or deficit
Because the actual evaporation can be measured precisely, we can calculate from weather stations data if more or less precipitation fell than your crop has evaporated. Once your plants more evaporate then there was precipitation, Fieldlook indicates a precipitation deficit. The value in millimeters per two weeks shows how much extra water from the soil is used or has come.

Reference evaporation
The evaporation of grass that has sufficient water at the given weather conditions. This value indicates how many millimeters of water per week would evaporate if your specific field was growing grass at maximum conditions.
