Relation between soil and foliar fertilization of permanent meadow

The aim of the study was to estimate the influence of changing mineral content in the soil on the meadow yield in the permanent meadow experiment. The following treatments were applied: control; PK+220 kg N/ha; PK+110 N; PK+110 N+ foliar fertilization; PK+55 N; and PK+55 kg N + foliar fertilization. The studies have revealed that the investigated fertiliser combinations gave similar results of the total content of macro- and microelements in the soil. Using lower nitrogen doses to soil together with foliar fertilization positively affected yielding of a permanent meadow which can be important for soil protection. Efficiency of foliar fertilization was higher with the lowest nitrogen dose supplied to the soil which suggests its ecological safety.
