Soil moisture update by VanderSat – Europe June 2021

June 3, 2021


op level summary for 3rd of June 2021

Drought hazard Spain and Greece/Turkey


The 2021 crop season for spring and summer crops in Spain, Greece and Turkey started with relatively dry conditions in the topsoil of the earth until the end of May 2021.


  • This was the direct result of lack of rainfall in these regions. The expectation is the impact on winter crops will be limited and the previous conditions to be sufficient for sowing of summer crops to be successful (source).
  • New rainfall in the next few weeks will be critical however. In the next 10 days around 20mm of rain is expected in the North of Spain, Greece, Romania and Bulgaria and Eastern part of Turkey. No significant rainfall is expected in the rest of Turkey (source)  .

Rest of Europe: the growing season starts very wet

The Eastern side of Europe, ranging from Germany, Poland, Hungary, Romania up to Bulgaria started in April 2021 with relatively dry conditions of the topsoil. Sowing of sunflowers, maize and potatoes was delayed. Rainfall events in mid April mitigated this situation to a large extent. So these soil moisture deficits had little or no negative impact on yield potential, as, in most regions, soil moisture levels remained at adequate levels (source).

Soil moisture defined

How much water is in your soil? Soil moisture is a more direct measure of how much water is available for plants and therefore a critical predictor for yield. Rainfall only provides the input of water availability.  It does not account for evaporation, water runoff,  and the additional water stored in the ground.

VanderSat measures soil moisture levels at a unique high resolution of 100 meter by 100 meter globally. Farmers, cooperatives and agricultural firms are using our data on a daily basis to measure, manage and insure their crop growth in every stage of their development.
