Manure

Manure remains a key tool in the arsenal of an agronomist and gardener, ensuring the restoration of soil fertility and the improvement of soil structure. This selection of materials covers a wide range of issues: from a detailed analysis of the physical and chemical properties and rheological characteristics of liquid manure to the applied aspects of using organic matter as biofuel for heating hotbeds. The articles explain the complex impact of organic fertilizers on the "soil — microorganisms — plant" system, which allows for the replenishment of humus and the creation of an optimal nutrient environment for various crops.

In addition to practical recommendations on fertilizer application, the selection includes materials on the agrochemical analysis of substrates, methods for calculating nutrient application rates, and the correction of soil conditions through liming. Readers will find detailed data on the nutritional characteristics of vegetable and flower crops and sugar beet, as well as the general principles of agrochemistry as a science. A historical overview of the development of agronomic thought, starting from the Middle Ages and ending with the formation of the Russian scientific school, helps to gain a deeper understanding of the fundamental patterns of plant nutrition and the evolution of methods for their top dressing, which remain relevant in modern agriculture.
