Prolonged differentiated mineral fertilizer application had a negative effect on field crop productiveness within 6-7 years after switching to full NPK fertilization.
“The negative effect of prolonged differentiated application of mineral fertilizers on productiveness of the agrophytocenosis is shown within 6-7 years after a transition to applying combined full mineral fertilizers (NPK)”
