To avoid common fruit quality issues such as BER in tomato and pepper it is important to have EC under control in time and stable between days.
Using the GroSens look at how the EC develops over time, especially in relation to radiation, it should be stable from day to day. In this respect it is also very important to have EC refreshed in time during the day. Look critically to the recorded time of first drain on the computer and compare this to the time EC decreased in the slab indicated by the WCM, they should match. But in many circumstances drain will be recorded but EC will not be controlled (Figure 1). If left unchecked this can have devastating consequences for the crop.
