THE INFLUENCE OF FERTILIZERS UPON GRAIN CROP QUALITY AND PRODUCTIVITY IN THE DERNO-PODZOL SOILS IN UKRAINE VOLYNSKY POLESYE (WOODLANDS)

Abstract

The paper provides research data on the timely and burning subject of farming biologization, particularly the development of technologies to improve farm crops productivity at the expense of bacterial formulations application. It also conveys the information about the results gained in the productivity and quality of the crops of grain five-course rotation in the backgrounds of mineral and biological fertilization systems with Biogran, Rizogumin and Microgumin applied. It was established that under the conditions of Ukraine Volynsky Polesye (woodlands) and in the derno-podzol sabulous gley soils, the treatment with the bacterial formulations, such as Biogran and Rizogumin, within the biological fertilization system increased the productivity corn for green mass by 6.3 t/ha and Austrian winter pea by 0.9 t/ha with concurrent improvement in the cultivated crops quality
