The crop rotation of the field includes the previous crop of wheat and the next crop – corn.<\/p>\n
So far, the field has been ploughed, using conventional technology. Due to the specifics of the trail layer, as well as the result in terms of mechanical composition and specific electrical conductivity, the first goal is set – to improve the soil structure.<\/p>\n
Since the alkaline reaction of the soil determines the digestibility of vital elements for the next crop – corn (such as phosphorus, zinc, manganese, iron, etc.), it is important to emphasize. Therefore, the next priority is to improve the mineral cycle.<\/p>\n
The objectives of the experiment are also to study several conservation practices – cover crops, minimal tillage, direct sowing; mulching and the efficiency of chemical and mechanical termination of roof crops, mulching, etc.<\/p>\n

Set mixes and sowing of cover crops<\/h2>\n
The experiment included three mixes of cover crops, one of which was divided into inoculated and non-inoculated seeds. The mixes are balanced between cereals, crucifers, legumes and other deciduous trees.<\/p>\n
Mix 1<\/strong> – oats, clover, vetch, turnips, millet, sunflower – inoculated Oat, rye and coriander seeds are inoculated with mycorrhizal fungi, and clover, vetch and peas are inoculated with nitrogen-fixing bacteria.<\/p>\n Root crops are sown directly in wheat stubble with a disc seed drill. No other tillage was done before sowing. Sowing took place on October 1, 2020, and rain on October 2-3 provoked the germination of seeds next week.<\/p>\n <\/p>\n In the mixes, given the date of sowing, we selected freezing and overwintering crops in different combinations and norms. We sowed each of the mixes on an area of \u200b\u200babout 25 decares, says Boris Koev.<\/p>\n It is important to note that due to late planting, especially sensitive to low temperatures crops do not emerge (sunflower, silage sorghum, millet).
