Phosphorus is a key macronutrient that determines crop productivity and soil fertility. Proper management of phosphorus nutrition requires an understanding of the chemical properties of fertilizers, the mechanisms of their interaction with the soil adsorption complex, and the specific agrochemical requirements of various plants. The efficiency of a fertilization system depends not only on the choice of the preparation, whether it be nitrogen-phosphorus mixtures or citrate-soluble compounds, but also on taking into account regional soil and climatic conditions that ensure the balanced development of vegetable, forage, and grain crops.
This selection combines fundamental knowledge and practical recommendations for working with phosphorus fertilizers. The materials cover the entire cycle: from the extraction of natural raw materials and industrial synthesis technologies to methods of application in crop rotation and the assessment of the impact on the ecological state of water bodies. Readers will find here the historical context of the development of domestic agrochemistry, guides to the agrochemical analysis of substrates, as well as applied strategies for increasing land productivity — from greenhouse complexes and field lands to fish-farming ponds.
