Influence of organic fertilizers on the water and food regime of meadow-chernozem soil

The research is based on the results of studying the effect of solid organic fertilizers based on cattle manure (cattle) of various storage periods on the supply of productive moisture and the chemical composition of meadow-chernozem soil. The studies were carried out at LLC RUSKOM-Agro, Omsk region in 2017-2018. The application of organic fertilizers significantly increases the content of nitrate nitrogen (from very low to very high levels), mobile phosphorus and potassium. In the first year of aftereffect, manure doses continue to have a significant impact on the nutrient regime of the soil. Moisture reserves before sowing were characterized as good (133-154 mm) without significant changes when applying manure.
