THE IMPACT OF NUTRIENT ELEMENTS ON THE MECHANICAL COMPOSITION, WATER-PHYSICAL PROPERTIES AND MELIORATIVE STATUS OF IRRIGATED MEADOW BROWN AND MEADOW SOILS

Аннотация

Soils are diverse in terms of type and composition. Under the influence of various factors (fertilizers, irrigation, etc.), soil properties can change. Soil fertility depends more on the nutrients added to the soil during tillage. The demand for organic food production is increasing, which requires a revival of the practice of using organic fertilizers, including non-conventional fertilizers. One of these organic amendments is compost made from waste and plant residues. In this research, we investigated the effect of compost ratio and amount on the physicochemical properties of irrigated meadow-brown and irrigated grassland soils. The relevance of the topic is that the mechanical composition, water-physical properties and meliorative condition (used fertilizers) of irrigated meadow-brown and grassland soils studied in the research were influenced by nutritional elements.
