Potassium is one of the key elements of mineral nutrition, determining the productivity of crops and the intensity of metabolic processes in plant organisms. Its role in ensuring a high harvest, product quality, and plant resistance to adverse factors can hardly be overestimated. Understanding the principles of potassium nutrition, from the chemical properties of fertilizers to the technologies of their application to the soil, is a basic skill both for professional agronomists working on an industrial scale and for owners of backyard plots striving for the stable development of their plantings.
This collection includes materials covering a wide range of issues: from the production and classification of potassium compounds to the development of individual nutrition systems. Readers will find detailed reviews of simple and concentrated fertilizers, innovative formulations, as well as recommendations for their effective use for grain, vegetable, and fruit crops, and forage lands. In addition, the articles cover historical aspects of domestic agrochemistry, methods of agrochemical analysis of substrates, and regional specifics of fertilizer application, which allows for forming a comprehensive understanding of the rational use of resources to obtain a high-quality harvest.
