Many farmers sow sideratny cultures for improvement of fertility of the soil. Siderata, or green fertilizers, is simplicity, availability, environmental friendliness and, the most important, - economy of family purse because good manure costs considerable money and it to get presently not easy.
Choice of sideratny herbs today wide. But most of summer residents prefer to sow white mustard. It is available, quickly ascends, quickly gathers green material. When redigging the soil it is easy to work with it. But mustard has essential shortcoming. It belongs to family of cruciferae family. And it is everywhere the grown-up vegetables: cabbage, garden radish, turnip, radish, daikon, etc. All of them are united by such disease as kil and the wrecker cruciferous flea beetle. And it can become big problem on the small parcel. Whether it is better to apply various siderata? For example, lupine from family of bean.
In what lupine advantage as siderat?
It in agronomics is considered standard of siderat. To soils the lupine is not exacting, well grows both on sour, and on average and sour soils. Its roots deeply get into the earth, using almost insoluble phosphates. The lupine quickly decays when redigging, increases fertility of arable layer, loosens and improves physical properties of the soil, changing its structure.
The lupine is one-year and long-term and belongs to cultures hygrophilous and cold-resistant. This plant of long day.
Lupine seeds on 1 hundred part 0.3-0.4 kg are necessary that after redigging of green material is equivalent to introduction of 400 kg of manure. Such soil can be used within two years without application of fertilizers.
The harvest of the grown-up such widespread vegetables as tomatoes, potatoes, pepper, eggplants, any root crops after lupine increases by 2-3 times. It is important that many diseases of these cultures are deprived of opportunity to develop on such soils.
Council. At early crops of seeds of lupine to the crude soil in the spring, shoots will be amicable and uniform. In August, at formation of flower arrow at lupine plants, it is necessary to dig over the site, closing up green material of grass to the earth. On the dug-over site it is possible to seed seeds of fast-growing siderat, for example, again of colza or fatseliya (it is possible to mix them), spending 250-300 g of seeds for hundred part. By winter to dig over the bred grass again. Such prepared site is ready for operation within 2-3 years, without introducing any fertilizers.
