Solid turf when the amount of fertilizer did not provide the optimum level of nitrogen in the leaves of the tree. Mineral fertilizers in the dose of N96P96K96 provided the optimal content of phosphorus in the leaves on the black pair at 0,42% and through-terraced turf - 0,39%.,potassium respectively 1,20-1,28%.
