In the south of Russia and Ukraine the deep redigging of the earth is undesirable, but without it the soil becomes dense and grows with weeds. Therefore it is possible to apply the Canadian technology.
Instruction
1. In the first year it is necessary to sow "warm" cereals (corn, sorghum, Sudanese grass) and "warm" broad-leaved bichromatic plants (sunflower).
2. It is necessary to imprison beds for the next year "cold" cereals (barley, rye, oats) and broad-leaved bichromatic (colza, Vika, peas, beans, haricot, potatoes) which transfer the lowered positive temperatures.
3. At the same time core roots get on depth up to 62 cm, fibrillose - up to 45 cm, corn (fibrillose) and soy (core) - are located mainly in surface layer of 25-40 cm. Core roots, rotting through, leave in the soil of cavity on which precipitation gets into deep layers, and plants with fibrillose roots loosen surface layers. Placing cultures, consider that after corn it is impossible to sow cereals, and at their cleaning it is impossible to leave high eddish.
4. The crop residue remains bean and cereals serve as mulch, but as under it the soil gets warm worse (more slowly and unevenly), under "warm" cultures sow strips (width of 70 cm) of siderata and introduce phosphorus-potash fertilizers. The row remains black and quickly gets warm. The vegetable mass of corn decays in three years, wheat straw - for two, peas and beans completely rot through within the next year. As the solomisty remains are poor in nitrogen, add its starting dose (10 kg on 1 t of the vegetable remains).
