What is it and what is it for
Gardens are plants of certain species that are sown in fields and plots, and then mowed, left to overripe on the surface of the ridges or buried in the soil, where overripement also occurs.Green mass acts as an organic fertilizer, its quality can be compared with humus. In addition, the soil structure is improved and ennobled.
Siderats are not only fertilizer: while they grow in the beds, they inhibit weeds, accumulate nitrogen near the roots, loosen the soil, saturate with oxygen, reduce the number of pests, stop the spread of diseases.
When you need to sow green manure in autumn in a greenhouse
In autumn, sowing seeds in a greenhouse should be done after the final harvest, when plant debris has been removed. Depending on the crop that grew under cover, and the method - for digging or before winter - planting should be carried out at different times.
In order for green manure plants to grow enough to be planted in the soil, they need to be sown from late August to late September. At the end of October and November, sow seeds that will remain overwinter and germinate only in spring.
What to plant?
Most types of green manure belong to the cruciferous and cereal families. But certain green manure varieties are suitable for certain crops in the greenhouse. There are also limitations: you can not choose green manure and culture that belong to the same family, so as not to carry the disease. If green manure is used on the site for several seasons in a row, then you cannot plant the same plant, you need to alternate green manure species.
For tomatoes, peppers and eggplants
For representatives of the nightshade family, legumes, cereals and cruciferous plants will be good predecessors. You can also sow phacelia, goat's rue, lupine, buckwheat. Any of these plants will be able to increase the yield of popular garden crops by a third. And when planting seedlings in the soil where green manure grew before, it will protect it from pests.
After nightshade, it is recommended to sow radish, mustard, phacelia. Plants will cleanse the earth of late blight pathogens and fill it with nitrogen.
For cucumbers
Cucumbers have a superficial root system, they take nutrition from the top layer of soil, so it should be the most fertilized. Under this crop in a greenhouse, it is permissible to plant almost all common green manure. From spring and the whole summer, you can also sow plants in the aisles. This will only improve the taste of cucumbers. It is not recommended to sow rye before crop. It is believed that it suppresses not only weeds, but also cucumbers.
After greenhouse cucumbers, legumes or a vetch-oat mixture are sown. Plants will be able to restore depleted soil and bring nitrogen into it.
For other crops
In the greenhouse in autumn, you can sow any green manure, if they can sprout and grow 15-20 cm before the onset of cold weather. If it is supposed to leave green sprouts to winter, then winter cereals can be sown.You can also mix seeds of different crops and sow at the same time. The benefits of the mixture will be greater, since all plants act on the soil in different ways and accumulate elements in different proportions. This will universally prepare the land for different crops.
How to sow green manure
First you need to prepare the beds in the greenhouse. Remove all remaining stems, roots and tops from the previous crop. Take everything out and burn it. Dig up the ground, remove the roots of the weeds. Level the soil, sow green manure to a depth of 3-4 cm. Pour water and sprinkle with a thin layer of soil. Compact the soil a little. Sprinkle with a layer of humus to help plants grow faster.
When sowing before winter, you need to spread the seeds thicker, some part may not survive the winter.
In cold weather, if the plants in the greenhouse are left uncut, they are sprinkled with snow. In the spring, crops should be sown when at least 2 weeks have passed after harvesting green manure. This is necessary so that in the soil they have already begun to overripe and feed the seedlings.
Green manure in a greenhouse is a great way to prepare and fertilize the soil, cleanse it of pathogens and harmful insects, and improve the soil structure. Experts advise sowing green manure plants in a greenhouse for at least 3-4 years in a row to see the result and fix it.
