Siderates for improving soil structure.


Siderates are one of the most affordable and safest ways to improve the soil. Natural natural processes are used for this. Plants, thanks to their properties, help to improve not only the structure of the soil, but also to enrich it with nitrogen and reduce the growth of weeds, as well as increase soil fertility.


Types of siderates are divided into several types by action and purpose:

  • soil loosening
  • nitrogen fixation
  • mulching
  • increasing fertility
  • protection against pests

Advantage of sideration

Unlike other methods of improving soil properties, sideration has a number of advantages. One of the main ones is environmental friendliness. Due to the unique property of the plant, the land improves naturally. The second advantage is accessibility, compared to other methods.

Soil loosening.

Soil loosening

The main principle of operation is a widely branched root system in certain plants. The roots make it possible to loosen the lower layers of the soil well.

These plants include:

  • sunflower
  • oily radish
  • lupine
  • mustard

Nitrogen fixation.

Fixation of nitrogen is necessary for plants, as it is the most important element of nutrition. Nitrogen is constantly depleted, and nodule bacteria live on leguminous plants. They, in turn, assimilate atmospheric nitrogen from the soil and provide nutrition.

These plants include:

  • peas
  • beans
  • willow
  • clover
  • lupine


The soil is prone to external destructive factors. Siderates with a thick green mass or with a powerful root system can protect against various actions of the environment. It can be erosion, overheating, freezing or drought. Siderate plants can also help in the fight against weeds. Such plants include:

  • mustard
  • phacelia
  • lupine
  • marigolds

Increasing fertility.

Increasing fertility

Due to the fact that some siderates act as a natural source of organic substances, they are called “green fertilizers”. This is due to the fact that such plants are a source of energy for special microorganisms that, in their own species, secrete useful substances. They increase soil fertility.

These plants include:

  • lupine
  • clover
  • rapeseed
  • oil radish
  • oats
  • winter rye

Protection against pests.

Nematodes, cabbageworms, caterpillars, wireworms, slugs and other pests are a headache in agriculture. But some plants can scare away pests, improving the situation in the field.

Siderates can help scare them off:

  • oil radish
  • marigolds
  • yellow mustard
  • lupine
  • phacelia
  • rapeseed
  • oats

Sowing siderates.

Sowing sideratov

All siderate plants are planted in almost the same way. They are spread evenly over the surface of the earth and, after that, carefully deepen the seeds with a rake.

As a rule, siderates grow in one and a half months and are mowed before they bloom. After that, it is necessary to dig up the ground together with the cut plants. They begin to decompose in the soil and additionally enrich the earth.

But there is an exception. Of course, it is not necessary to mow honey-bearing siderates, since the purpose of their use is different – collecting honey or attracting honey-bearing insects. But these questions are not related to this topic.

Disadvantages of siderate plants.

The only drawback of using such plants is that some types of plants cannot be planted one after the other. This refers to plants from the same family.

After legumes such as lupine, vetch, clover, alfalfa, leguminous vegetables – peas, beans and beans – cannot be planted. Accordingly, it is not possible to plant cereals after cereal siderates, and after cruciferous siderates – cruciferous.

More details about some siderate plants.

Avid rapeseed is sown in the spring – at the end of March or at the beginning of April. Winter in autumn – from August to October. This plant suppresses buryani, enriches with useful trace elements, repels the wireworm, and also suppresses some causative agents of potato diseases. In addition, it attracts bees and other pollinating insects. You cannot plant before or after cruciferous plants: cabbage, radish, radish, turnip, etc.

Mustard is planted both in autumn and spring. It is effective against many diseases and pests. Mustard loosens the soil, fills it with organic matter, thereby fertilizing it. It comes in different types, but white and Sarepta are used as siderates.

Lupine is a leguminous plant that is used on dense soils, saturating the soil with nitrogen and potassium. Also repels many pests. Lupines are planted in April, but it is better in August, mowing it one and a half months after emergence.

Maslenichnaya radish contributes to the accumulation of humus and organic matter, loosens the soil and helps against many pests. Moreover, it inhibits some potato diseases. You can sow 3-4 times per season, mowing after one and a half to two months. If it was planted in late autumn, it should be mowed in the spring.

Oats saturate the soil with useful substances. Also, this siderate suppresses weeds and repels nematodes. It is sown either in winter, or in spring and at the end of summer. Oats are harvested when they grow up to 15 cm. After this plant, it is recommended to plant tomatoes, peppers and eggplants. But it is not recommended to plant potatoes.

Siderates are an effective, affordable and environmentally friendly way to improve soil quality. And a competent approach to the selection of these plants will solve problems with the quality of cultivated plants and increase the amount of harvest.
