Exchange of best practices

Practical application of researches of SSAU scientists - agrochemists

Teachers of the department of biochemistry and plant physiology, together with representatives of the mineral and chemical company "Evrohim" laid in a production environment of Ltd. "Luch" Novoselitsk territory demonstration and field trials. Scholars and practitioners set out to scientifically substantiate the use of fertilizers in order to optimize the conditions of mineral nutrition of crops, in particular, to compare the quality of traditional forms of nitrogen fertilizers used in the farms of the region (ammonium nitrate and urea-ammonia mixture). The significance of nitrogen application in the production in modern conditions of winter crops has increased due to the fact that the saturation of arable organic fertilizers has decreased significantly over the past 15 years, stocks of available nitrogen compounds in soils are often insignificant. At present, when the volume of the main application of fertilizers is restricted, spring nitrogen fertilization for many households is the main reception of fertilizer application under winter grains of cultures. winter wheat fertilizing eliminates the lack of nutrients in the growth period. As a rule, in the early spring due to adverse regime and excess nitrification in the soil moisture is suppressed. The resulting plants starve from lack of nitrogen and reduces the yield. Applied fertilizers were implemented by the surface means to the area of 50 hectares. As a result of production experience, agricultural producers will receive recommendations on the timing, forms and doses of nitrogen fertilizer application.
