At the "Ukraine-2001" farm in Khmelnytskyi, a unique study was conducted to determine the optimal rates of digestate, which is obtained after processing livestock waste in a biogas plant. It was found that the most economically justified and most effective dose for applying digestate under corn is 70 tons per hectare. Also, thanks to the high rates of digestate, it is possible to obtain up to 100 tons per hectare of sugar beet. The main thing is not to exceed the optimal rates, as this would reduce the yield.
