This study analyzes how agrochemicals affect nitrogen in sod-podzolic soil and productivity of cereals, indicating significant improvements in crop nutrient composition.
The effect and aftereffect of agrochemicals obtained by mesophilic-thermophilic composting of organogenic by-products (manure of cattle, bird droppings and a mixture of urban wastewater sediment with sawdust) on the nitrogen regime of sod-podzolic sandy loam soil, the productivity of cereals in the crop rotation, their macronutrient composition were studied. It is concluded that these agrochemicals based on by-products of animal husbandry and sewage sludge significantly influenced the nitrogen regime of the soil, the productivity of the grain component of crop rotation and the macronutrient composition of crops.
