Description
Alternation of crops, will remain a fundamental element of zonal technologies of their cultivation for a long time. Application of methods of mathematical model operation will allow to come to new level in the solution of the questions of effective use of an arable land, through application of models optimizing it. Results of researches which basis data of long-term observations are will be especially valuable. They used data of the long-lived stationary experiments on studying of alternation of crops in crop rotations of last more than five rotation. Stationary experiences are located in a forest-steppe zone of Western Siberia on the fields FGBNU "SIBNIISKH". The purpose of researches consisted in optimization of use of an arable land at application of methods of mathematical model operation for preservation of soil fertility. The model allowing when performing particular conditions is given in work (balance of a humus, work expense, a metabolic cost, etc.) to optimize use of an arable land against the background of preservation of soil fertility of the soil, receiving production, economic and power efficiency. It is shown that at alternation of grain crops with clear steam, formation of a harvest happens due to natural fertility of the soil what the negative balance of a humus which reaches 0,18 – 0,78 tons from hectare testifies to. At alternation of field cultures without clear steam the harvest was formed against the background of reproduction of organic matter of the soil, due to increase in vegetable oddments from use of fertilizers, the balance of a humus was positive – 0,15 – 0,28 tons from hectare. Use along with clear steam, busy steam, colza on green fertilizer, and also straw as organic fertilizer for grain crops, 2,01 tons from hectare of commodity grain were received, at a share of clear steam – 16,8%, busy steam – 11%, summer grain – 72,2% of arable land. Increasing in crop rotations of West Siberian Square with use as organic fertilizer of straw, busy vapors and green fertilizers, it is possible to achieve reproduction of fertility of the soil with some decrease in an exit of commodity grain to 2 tons from hectare
