Every gardener is convinced that the grown vegetables in the garden should be environmentally friendly. Therefore, many do not use chemical fertilizers in their gardens. For a good potato harvest it is very important that the soil is not depleted.

If you categorically reject the use of chemical fertilizers, then green mans will come to the rescue (they decompose quickly and do not leave harmful substances). Using sideratov can increase the yield of your potatoes on the site.
The best siderata for potatoes
Green plants can be annual plants with a well-branched root system.: peas, sweet clover, lupine, sardella, alfalfa, chickpeas, beans, lentils, soybeans.
The sideroot roots, loosening the soil, improve its structure, and the tops of it fertilize and mulch the soil.Siderats guarantee the replenishment of minerals in the soil on which it is planned to plant potatoes.
A good siderat for potatoes (albeit with a lower percentage of nitrogen) is rape, mustard, colza, fatselia, oats, rye, wheat. These cultures protect the soil from weathering, dehydration, enrich with useful minerals. When winter sowing, these plants will save the soil from deep freezing and delay the snow.
How to sow siderata under potatoes
Before planting siderats, the soil is well loosened - the plants must fully develop and give a sufficient amount of green mass.
Siderates for potatoes are sown in autumn 1.5 months before the onset of cold weather - in September. The sideratov seeds (best of all, cereals - they tolerate the winter well) are scattered on the surface of the plot, and then plowed in with a rake. You can plant seeds in shallow grooves (2-3 cm deep).
Fresh sowing is covered with a thin layer of compost. In May, siderats are harvested and potatoes are planted in their place..
If sowing is planned in the spring, the green manure should fall into the ground in late April - early May (the ground should warm up by 3-5 cm). Very good mix of spring sedertov: oats, fatsely, white mustard.
2 weeks before planting potatoes, siderats are cut by a flat-cutter and they dig up the soil to a depth of 8-16 cm. During this time, the green mass will have time to turn over and become a good fertilizer.
Potatoes on the site, fertilized with green manure, planted to a depth of 5-6 cm. Practiced planting potatoes with mustard. This method of landing has several advantages: mustard loosens the soil, "clogs" weeds, retains moisture, frightens off pests.
When the potato leaves and mustard are equal in height, mustard must be removedso that potatoes can fully develop. Cut plants can be left in the aisle, and can be taken out in the compost pit.
Planting potatoes after sideratov
In 2 weeks after harvesting sideratov you can start planting potatoes. This time is enough for the green biomass, slightly stuck in the ground, to rot and enrich the earth with minerals.
Tubers are planted in holes (or grooves) to a depth of 5-7 cm. For constant soil loosening, buckwheat or mustard over potatoes is used. Such a neighborhood will allow the soil to be loosened by siderates.
Buckwheat is able to reduce the acidity of the soil, to enrich the soil with phosphorus, potassium, and organic components. But when the tops of the potatoes become equal in height with sideratami, the latter are pruned (the potatoes must develop well).
What is sown after cleaning
In order to increase the future harvest on the site, it is recommended to use siderats immediately after harvesting potatoes.
The soil is sown for winter oats, peas, white mustard. In spring, these plants are cut. They can be left on the garden, slightly prikopav or sprinkled with earth. Green manure rot and become a good fertilizer for potatoes.
It should be remembered that the potato greatly depletes the soil on which it grows. That is why you have to enrich the soil with environmentally friendly fertilizers for the next planting season.
