Steam field, to be exact steam – this field free throughout everything or a part of the vegetative period from crops of crops during which it systematically process for weeding from weeds and moisture preservation.
Depending on duration of the period of a parovaniye distinguish pairs pure and busy. The pure steam plowed in the autumn, is called as black steam, and plowed in the spring – early. Steam fields take away, as a rule, under crops of winter wheat and a rye, in some areas sow also spring wheat. A fallow land enters mainly in droughty areas of the Steppe and the Forest-steppe.
The occupied steam – a field in a crop rotation under crops winter, occupied on an extent of the first half of summer early being cleaned cultures. Cultures should not only provide with Parozanimayushchiye the corresponding exit and in due time liberate a field for soil preparation under winter, but also favorably influence it – to raise the content of nitrogen, to improve a fytosanitory condition, to clear of weeds.
Version of busy steam which apply under winter crops, – kulisny and sideralny. In the kulisny sow a slip (strips 1-3 categories) highly stebelny plants. Their mission – detention of snow and moisture accumulation in the soil, protection winter from dusty storms, blowing and a vymerzaniye.
Sideralny steam is the occupied steam on which grow up bean and other cultures, thus their green material pripaxivayut on green fertilizer. Enter it mostly in areas of sufficient moistening in poor nutrients soils, and also in the conditions of irrigated agriculture.
Given by many scientists – classics of agriculture classification parov and care of them has important technological value. Nevertheless, now it prizabyta and practically isn’t used by practicians of agricultural production as the main agrotechnical protection against weeds, diseases, wreckers and infections. It is heavy to underestimate ecological value parov. Therefore it is necessary to add them to the arsenal, to carry out an innovation of scientific development by farms in all zones of Ukraine.
