Drought stress - Emergency harvesting or hope for further yield

Drought conditions have been prevailing in Central Europe for several months, with no end in sight.

The persistent heat and the lack of rain are reflected more and more clearly in the rolled and dried leaves of maize, beets are also wilted. Farmers are already talking about the worst harvest in the last 20 years.

The persistent drought stress is particularly evident in maize crops. On the headlands of many fields, you can see untypically short, partly unfertilized maize plants. This results in low-piston populations and extreme yield losses.

The first maize crops have already been hwarvested in the last few days with regard to the dry matter content in order to ensure sufficient compactibility of the harvested crop.

According to the Chamber of Agriculture of Lower Saxony, "it is important not to rush to harvesting. It is possible that this will cause the greatest damage, as the maize can still produce a yield, depending on further weather conditions."1

With the regularly updated biomass maps from My Data Plant, the farmer can monitor his crops. From the beginning of vegetation, he is able to look at problem areas and observes how drought stress develops in his fields. With the biomass maps of My Data Plant, the farmers has additional information to base his decision on when to begin harvesting. The images show him whether the vitality of the field is so low and should be harvested or whether the whole field is so good that it can still be left standing so that it can respond to any rain and optimise yield.
