Physical properties

The physical properties of soil and fertilizer form the foundation of modern agronomic practice. Understanding the soil texture, its density, porosity, and structural features allows an agronomist to manage soil fertility competently. In turn, knowledge of the physicochemical characteristics of mineral and compound fertilizers — such as hygroscopicity, solubility, and component compatibility — is necessary for effective planning of plant nutrition systems and selecting optimal application rates of nutrients for specific crops.

This collection brings together materials that reveal the relationship between the structure of the arable layer and yield. Readers will find articles on the classification of soil types, humus formation processes, and methods of mechanical tillage. A separate block of materials is devoted to production technologies, properties, and rules for mixing mineral fertilizers, from simple potassium to complex nitrogen-phosphorus compounds. Studying the presented theoretical aspects and practical recommendations will help professionals and gardeners approach the management of the agrophysical indicators of their plots and the selection of agrochemical agents more consciously.
