The rule of thumb in the hobby gardener area is that there is always one green manure on one Vegetable patch should be sown if there is a break in cultivation of more than six weeks. Green manure protects the earth's crumb, because it provides the soil with the necessary shade and also prevents the soil from being silted up, which can result from heavy downpours.
Loosening of the soil through green manuring
Green manure causes deep roots to permeate the soil and loosens it up accordingly. Even after mowing, the green manure is still effective for the soil, because the cut can be mulched and thus permanently supply the soil with important humus. Around late summer, the harvested beds are sown with a winter foundation.
Green manure stores nutrients
In addition to the advantages of green manuring already mentioned, this also means that as a fast-growing crop, it still absorbs the soluble nutrients in the soil and stores them in the soil over the winter. The nutrients cannot be washed out and offer the new vegetables good growth conditions again in the spring.
The green manure must be worked into the soil at least three weeks before planting the vegetables, whereby wintergreen must be chopped particularly well, which is not necessary for summer manure.
