Abstract
Potato growing is one of the main branches of agriculture, the main task of which is to obtain maximum yields of high-quality potato tubers.Therefore, the food security and stability of the country may significantly depend on the state of the potato industry as a whole.The urgency of the problem is related to the state of soil fertility, which is deteriorating almost everywhere.The purpose of the study: to develop an ameliorant as biochar for assessing potato yield and physicochemical properties of sod-podzolic sandy loam soil.The carbonised biochar obtained by pyrolysis of rice husks at a temperature of 400℃ was used as an ameliorant.Rice husks are used as a more affordable and cheaper material.It has been established that the use of biochar in agriculture leads to high crop yields at lower water costs.The introduction of biochar into the soil accelerates biological processes and promotes long-term soil fertility.Not only agricultural parameters are improving, but also the efficiency of biochar for storing carbon dioxide is increasing.
