Siderata are special plants that contribute to the structuring of the soil and its saturation with useful substances. You can plant them at different times. As winter green manures, annual plants are used, which have developed roots and a rapid build-up of vegetative mass. Thanks to this, the plants loosen the soil. The cut green mass is used as a mulching material.

What are winter green manures for?

It is permissible to plant siderata at different periods of time. This is done in spring, summer, early autumn. Sowing of plants in winter is also possible. At the same time, it is important to prevent the ripening of green manure, as they can go into the category of weeds. A good effect can be achieved when mowing greens with a shoot height of 20-30 centimeters or during budding.

Podzimny planting of green manure has many advantages:

  1. Saving time when planting vegetables in spring. This applies to cabbage, potatoes, carrots.
  2. Increase in the period of stay of green manure in the soil structure. They can stay there until May. This improves the loosening of the soil by the roots and promotes the release of mineral salts, which are required for late crops.
  3. Protection from the spring sun and return frosts. This effect is achieved through the abundance of greenery. After mowing, shoots and leaves can be used as cover mulch.

Which one is better to choose

It is recommended to choose siderata depending on the culture. Such plants belong to different families and differ in certain characteristics. So, to cleanse the beds of keels, it is forbidden to plant cruciferous vegetables - mustard, radish, turnip.

In addition, plants differ in terms of germination time, vegetative cycle and soil requirements. So, peas develop well on light sandy loam soil. At the same time, it does not grow in heavy soil. Beans and beans should be planted in loamy soil.

It is important to take into account that plants differ in functionality:

  1. Legumes - help to saturate the soil with nitrogen.
  2. Cereals and cruciferous plants - fix nitrogen in the soil. With their help, it is possible to convert minerals into a more accessible form and prevent demineralization of the soil.
  3. Rapeseed and rape - help to increase the humus layer due to the large amount of leaf mass. They are used as green top dressing.
  4. Phacelia, oats, buckwheat, lupine - help to reduce the parameters of soil acidity.
  5. Oil radish, white mustard, calendula, nasturtium, legumes - inhibit the activity of nematodes and pathogens of various pathologies.
  6. Phacelia, mustard, sunflower, annual ryegrass - have pronounced melliferous properties.

All green manure loosen the soil with its root system. This effect is especially pronounced in lupine, oil radish and beans.

Many plants in this category inhibit the growth of weeds. This is due to their high seeding density or rapid growth.

List of the best plants

It is recommended to choose green manure taking into account the tasks that need to be solved. At the same time, there are a number of popular plants that have a complex effect.

Vika

This plant contributes to the saturation of the fertile soil layer with nitrogen. Also, the culture provides protection for seedlings from attacks by slugs and birds. Vika successfully cleans the area from aphids and bears.

The disadvantage of a plant is the need for frequent watering. It is recommended to plant seeds in moist soil. With the arrival of spring, the greens must be mowed, and the soil must be dug up. After wiki, it is permissible to plant various vegetables and cabbage. At the same time, sowing legumes is prohibited.

Mustard white

This green manure does not need subsequent plowing into the ground. During severe frosts, its shoots and roots rot, but they manage to saturate the soil with useful substances. When planting white mustard, it should be borne in mind that it does not tolerate sour and marshy soil types.

It is recommended to plant the plant to a maximum depth of 3-4 centimeters. It is also acceptable to scatter seeds over the soil surface. It is required to mow shoots before flowering and ripening of seed material. Planting work is recommended at the end of August.

Winter rye

The culture grows beautifully lush greenery and easily tolerates frost. After this green manure should be planted with cucumbers, tomatoes, potatoes and pumpkin. The only drawback of the plant is a small amount of nitrogen, which is released during decomposition in the soil.

Winter oats

This green manure helps to loosen the soil, copes with parasites and weeds, saturates the soil with useful substances - potassium, phosphorus and nitrogen. Oats also contribute to the suppression of soil pathogens.

It is best to plant the plant in early autumn, so that it has time to get stronger by the arrival of cold weather. Oats tolerate winter well and help to preserve all the necessary trace elements in the soil. With the arrival of spring, the culture begins to grow rapidly. When the shoots reach 20 centimeters, it is recommended to mow the greens.

Rape

This green manure helps to structure the soil and saturate it with phosphorus, potassium and nitrogen. After this plant, it is permissible to plant tomatoes, eggplants, peppers. Rape is fast growing. When planting in autumn, it disinfects the soil and prepares it for the spring planting of garden plants.

However, compared to oats and rye, rapeseed is considered a more whimsical crop. It does not tolerate temperature fluctuations and the influence of high humidity. In such conditions, the green manure begins to rot and die.

Greenhouse work

Greenhouse plants require more care than ground plants. After digging up the soil, it is worth planting green manure. Mustard, rye, oats tolerate the cold very well. They manage to ascend to severe frosts and form a powerful root system. With the onset of spring, you need to dig in the greens. This will help to obtain valuable humus.
