Successional structure and useful condition of mowing-and-grazing landscapes

Abstract

The paper presents data on the indicators of livestock production, the number of farm animals and poultry in the Tyumen region. The characteristics and significance of near-village forage lands are given. The studied forage lands are assigned to the forest-steppe lowland latitudinal-zonal area of the Kurgan province and contain valuable species of herbs: Calamagrostis epigejos, Bromopsis inermis, Festuca pratensis, Vicia villosa Roth, Trifolium rubens L., Medicago falcata. The territory of pastures is used for mowing and grazing animals of the individual sector, which prevents sodding and degeneration and has a significant impact on the consistent regular change of the biological community (phytocoenosis, microbial community, etc.). The hay yield is 14.7 c/ha, which corresponds to natural meadows without cultivation. To improve the quality of hay and yield, the authors suggest carrying out agrotechnical measures: compliance with the terms of mowing the grass - a week before flowering or at the beginning of flowering of meadow grasses; introduction of potash fertilizers, which will increase the content of grasses in the herbage and will reduce the specific weight of forbs; application of nitrogen fertilizer in a mixture with potash and complete mineral fertilization, which will reduce the level of forbs by almost half; undersowing of leguminous grasses.
