Soil fertility is the foundation of efficient farming and the key to the stable productivity of agroecosystems. Understanding the physical, chemical, and biological processes occurring within the soil profile is essential for the competent management of crop nutrition and the preservation of land resource quality. This collection examines both the theoretical foundations of soil potential and practical tools: from the application of modern bacterial preparations, zeolites, and organic residues to methods for the scientific assessment of fertilizer efficiency.
The materials cover a wide range of topics: from fundamental works by classical domestic agrochemists to modern methods of conducting field trials. Readers will learn about the role of earthworms and microorganisms in humification, the influence of redox processes on the availability of nutrients, and the connection between the culture of farming and the level of a society's socio-economic development. The articles will help specialists and practitioners systematize their knowledge of optimizing the nutrition of agricultural crops and methods for restoring soil fertility under modern crop production systems.
