Investigation of the Potential of Potassium-Containing Additives Based on Mineral Raw Materials and Industrial Waste on the Quality and Yield of Potatoes

The soils of the Komi Republic are characterized as sod-podzolic. It is known that agricultural cultivation of such soils requires the introduction of various mineral and organic fertilizers, liming, deepening of the arable layer, and erosion control. The soils of the region are depleted of potassium, part of which is carried out by agricultural crops, therefore potash fertilizers, where potassium is in an affordable form, are among the most in demand in agriculture. This paper presents the results of a study of the material composition and textural characteristics of analcime-containing siltstones, potassium alkaline syenites and bark ash and their possible use as potash additives to improve potato productivity.
