Types of organic fertilizers and methods of calculating their needs to ensure a deficiency-free balance of humus in arable soils

Abstract

Long-term comprehensive studies conducted by the staff of the Institute of Soil Science and Agrochemistry together with scientists from specialized organizations of the republic allowed to establish a high positive effect of organic fertilizers and the need for their use in scientifically based fertilizer systems. The authors of the article systematized the results on the chemical composition of various types of organic fertilizers obtained and used in agricultural production of the republic. This information is necessary for making effective management decisions on the selection and use of various types of organic fertilizers, modeling and forecasting crop yields in the conditions of the Republic of Belarus.
