Determination of influence of botanical composition, mineral fertilizers and application regimes on forage quality was realized in the conditions of the Republic of Belarus. Research results showed that botanical composition did not render influence on quality characteristics of long-term used pasture grass stand density because of the compositional uniformity by the 23-rd year use. Nitrogen fertilizers increased the quantity of crude protein in pasture grass stand on 6-20% depending on fertilizer dose and lowered the amount of nitrogen-free extractive substances up to 8%. Potash and phosphorous fertilizers rendered influence on phosphorus and potassium content in forage, and increased the potassium content on 21-57% and phosphorous content - on 17-51%. Subtraction term of grass stand rendered influence on all quality characteristics of grass stand. The earlier subtraction terms caused the higher amounts of crude protein, crude fat, phosphorous, potassium and magnesium, and the lower amount of cruder fiber, nitrogen-free extractive substances, and calcium
