The article presents the results of studies on the effect of simple shapes and complex brand N10P19K25 fertilizer to prolong productive longevity pasture grasses. Simple forms of fertilizers in the amount N45P20-40K90 or complex in a dose N20P38K50(spring) and N30P57K75 (spring or N20P38K50 - spring + N10P19K25 after 2 cycles of grazing) are economically reasonable to increase the yield of herbage of the sixth-eight year use with legume content of 20%. This provides a yield per hectare pasture of 5,32-5,95 t / ha of fodder units at the lowest cost 14,6-20,4 USD / t.
