Sowing of green manure can be a spring and fall with the main crop before planting and after harvesting. Spring - thick, were to the wall, fall less often. In general, green manure crops can be grown throughout the season. In the early spring planting, when the snow just came down, pick up fast-cold-resistant plants - mustard, forage peas and oats.
Cultivated green manure, usually plowed within one to two weeks before planting the main crop. Or just cut the plant or hoe ploskorezom and leave on a bed at a depth of 2 - 3 cm, while retaining the structural roots of the work of green manure, and on the surface of the compost is formed over time from the foliage.
The effectiveness of green manure is highly dependent on plant age. Young and fresh plants are very rich in nitrogen, and rapidly degraded in the soil, so after the termination of their primary culture can be planted in 2-4 weeks, but not close up too much of the raw plant material, as it will not rot, and sour. Decomposition of plants more mature more slowly, but they enrich the soil with more organic matter.
Incorporation of green manure is recommended during budding before flowering at a depth of 6-8 cm in heavy and 12-15 cm in light soils. The soil under green manure crops should be well prepared, since the compacted soil, or roughly dug the plants will not develop enough green matter and will not give the desired effect.
Some crops (alfalfa, clover, alfalfa, vetch, winter rye) give a nice effect if you leave them on the field more than a year. Culture short season (barley, beans, peas, oats) can plow into the soil 6-8 weeks after sowing. We can not allow perestaivaniya plant green manure. They plowed into the soil before seed formation.
