Signs of nitrogen starvation are observed in winter rapeseed crops due to sharp temperature fluctuations.

In the central and southern regions, farmers are increasingly observing signs of nitrogen starvation in winter rapeseed crops. The reason is sharp temperature fluctuations and active mineralization of crop residues. This was stated by Serhiy Kornyushenko, the manager for agrotechnology development in the Southern region of LNZ Group. "The differences between day and night temperatures slow down the intake of nutrients by the plants. In particular, on most fields where rapeseed is sown, there is a blockage of phosphorus. The leaves of the crop acquire a violet hue, which is a typical manifestation of phosphorus starvation," he explains. Another factor that exacerbates the problem is the high amount of nutrient residues after the predecessor winter wheat and barley (which absorb nitrogen) and the surface tillage of the soil. Because of this, at the early stages of growth, rapeseed experiences a lack of this element. The specialist notes that in such conditions, an effective solution ...
