Abstract
Shows the estimated balance of humus in the soil for growing sunflower hybrids. The studies were conducted in the SEC - the collective farm "50 October" Neklinovsky district of Rostov region. The positive balance of humus in the soil is observed in growing hybrid Swallowtail + 0.18 t / ha. In the other crops hybrids had a negative balance of organic matter - minus 0.65 - 2.06 t / ha. With increasing sunflower yield over 2.54 t / ha are lost humus soil, which is not compensated by fertilization. Therefore, for the cultivation of high-yield hybrids need to take this into account and compensate for the loss of humus soil by introducing organic for other crops, or in a pair. Growing sunflower contradicts the rules of protection of the environment, if you stick to the principles of adaptive agriculture and integrated plant protection.
