Microelement

Microelements are biologically active substances whose deficiency in the soil becomes a limiting factor for crop productivity under intensive farming conditions. Despite low concentrations in plant tissues, it is these elements that determine the quality of the harvest, the biochemical profile of fruits, and their market appeal. Understanding the role of micronutrition allows an agronomist to build a precise fertilizer application system that takes into account the growing season stages, substrate types, and the physiological needs of specific plants, from vegetable crops to orchards.

In this selection, we examine a comprehensive approach to soil fertility management: from the analysis of agrochemical indicators to methods for calculating application rates of fertilizers. Readers will find materials on the principles of plant nutrition, the influence of the chemical composition of organic and mineral substances on soil structure, as well as the environmental risks associated with the excessive accumulation of elements. Special attention is paid to practical recommendations for the nutrition of tomatoes and vegetables in open ground and greenhouses, as well as regional fertilization systems adapted to modern agronomic requirements.
