The efficiency of sluicing of old-arable depleted peatlands depending on weather conditions during cultivation of perennial grasses

Abstract

The article analyzes the efficiency of sluicing of depleted peatlands with reference to the hydrothermal coefficient (HTC) during cultivation of perennial grasses against the various agricultural background for the period from 2014 to 2022. The sluicing efficiency, expressed as an increase in yield, is 30-40 % at HTC<1 without application of mineral fertilizers. After fertilizing, the efficiency of sluicing increases by 2 times.
