Questions on the agricultural use of depleted peatlands and their solution

The article highlights the results of long-term (50 years) stationary studies on the influence of different-level mineral nutrition of perennial grass stand, which is located in a drained lowland depleted peatland, on the productivity of agrophytocenosis, accumulation of underground weight, soil fertility, and content of peat organic matter. The application of mineral fertiliser has been identified to improve the botanical composition of perennial grass stand, increase its productivity by 1.9–3.4, accumulation of underground weight by 1.7–3.0, root nitrogen fixation by 1.5-3.1, phosphorus by 2.5-5.7, potassium by 1.1-1.7 that improves the soil fertility of peat and accelerates the accumulation rate of peat organic matter.
