英语. In course of the research there was studied the most effective ways of combinations of basic soil tillage (plowing to a depth of 20 - 22 cm, tillage with no loosening of overturning a depth of 16-20 cm and superficial tillage to a depth of 10-12 cm) and various systems of fertilizer, in the cultivation of maize (Zea mays) for green mass in anthropogenically-transformed peat soils. The research was realized in 2011-2012 on the lands of Polesje Experimental Station for Land Reclamation and Grassland Farming, Brest region (Belarus). As a result of realized research there were revealed that on anthropogenic-transformed peat soils the density level, moisture reserves, infestation of crops and maize yields during plowing and mulching (disking to a depth of 10-12 cm) at the same fertilizer systems differ insignificantly. This indicated that costly plowing for corn was quite possible to replace tillage harrow BDT-7 to a depth of 10-12 cm. Entering of increased fertilizer rates, optimized for compensation of the removal of nutrients and increasing of soil fertility not led to a significant increase (2.5%) yield of green mass in comparison with the case where the dose of fertilizer designed for removal returns + 10%, and nitrogen dose adjusted based on the soil diagnosis data of that element.

В статье представлены результаты исследований по выявлению наиболее эффективных сочетаний способов основной обработки почвы (вспашка на глубину 20—22 см, рыхление без оборота пласта на глубину 16—20 см и поверхностное рыхление на глубину 10—12 см) и вариантов систем удобрений при возделывании кукурузы на зеленую массу на антропогенно-преобразованных торфяных почвах.
