Phosphoric acid is a key component in the production of modern mineral fertilizers, which ensure proper plant nutrition for crops. Understanding the chemical processes underlying the production of substances such as simple superphosphate, ammophos, and precipitate allows agronomists and specialists to use resources more effectively for maintaining soil fertility. Knowledge of production technology features, as well as the principles of fertilizer interaction with the soil adsorption complex, helps in selecting the right compositions and optimizing plant nutrition systems based on their biological needs.
This collection brings together materials covering the entire phosphorus fertilizer cycle: from the extraction of natural raw materials, such as apatites and phosphorites, to modern methods of mixing and application of finished products. In addition to technological aspects, the reader will find information on fundamental works by domestic and foreign scientists who laid the foundations of modern agrochemistry. Studying these materials will deepen the understanding of chemical processes in the soil and help develop practical skills for managing nutrient regimes, which is essential for achieving stable harvests and rational farm management.
