Vico-oat mixture as green manure, sowing rates and timing, care rules


Fertilizing the soil is a serious problem that worries every owner of personal plots.

Many do not trust chemical fertilizing, believing that it can harm health, in this case, original methods of soil fertilization do not come to help, for example, a vetch-oat mixture is sown as green manure.

What are siderates, the benefits of their use

Siderata (green manure or green manure) - a group of plants that are sown for subsequent incorporation into the soil. After they form a sufficiently lush green mass, they are added dropwise.

Thus, it enriches the soil with nitrogen, with the suppression of the growth of weeds.

In addition, such fertilizers prevent the development of pathogenic fungi and bacteria that provoke diseases of cultivated plants.

Green manure is an environmentally friendly and absolutely safe alternative to chemical fertilizers.

Green top dressing replenish the reserves of nutrients in the soil without the danger of their excess.

Is planting green manures considered a crop rotation

Since sowing green manure plants requires a break from planting, the use of green manure also applies to crop rotation crops. In addition, when planting these varieties, it is important to take into account the individual characteristics of the plants, their chemical composition.

So, for example, mustard can be planted for preparing soil for potatoes, but mustard as a precursor is not suitable for representatives of the cruciferous family. Tomatoes are the best predecessor for the latter.

Planting of green manure plants is carried out as follows:

  • The site is cleared of weeds, the soil is loosened;
  • Seeds are not sown thickly to enhance the growth of green mass;
  • After the flowering period begins, the greens are cut and embedded in the soil.

As with any crop when crop rotation, it is important to take into account that green manures in the same place can be planted only after three years. Otherwise, there is a danger of saturation of the soil.

What plants are used as green manure, the percentage of vetch-oat mixture

Some of the most common plants used as green manure are vetch and oats, which provide a high percentage of foliage. The only drawback of the vetch is that it has overly fragile stems, so it is planted with cereals.

In general, it is legumes that are most commonly used as green fertilizers. This is due to the large percentage of nutrients that are part of the tops.

Vico-oat mixture is planted mainly in the fall, after the harvest is harvested.

There is no particular difference in the percentage of vetch seeds and oats when planting. However, for those who prefer accuracy, 20% seed wiki is enough, sometimes ten is enough. Landing can be done both in rows and randomly, there is not much difference.

How and when to plant oats and vetch, seeding rates

When planting, it is important to take into account that oats and vetch do not tolerate severe drought and a drop in temperature. Therefore, planting can be done either by autumn after harvest, or in spring, before the start of planting of the main crops.

The optimal time for planting in the spring is before the soil dries out, immediately after the snow melts. This period is optimal in terms of the amount of moisture, which means that spring seedlings will be as juicy as possible and should be cut off before the flowering period.

Thus, during the decay of green manure, a large amount of carbon dioxide and nitrogen is released.

With an autumn planting, the green mass will have time to form before the onset of cold weather. In this case, it is not necessary to cut the tops; it is enough to leave it for the winter until spring and, after the snow melts, it must be dug in, preparing the soil for planting the main crops.

The seeding rate per hectare is 180 kg. At the same time, 80 kg are allocated for oats, and 100 kg for vetch.

The surplus of green manure can be used for making hay or silage.

What kind of care is required

Caring for green manure plants is not particularly difficult, in order for the green mass to gain the maximum amount of nutrients it is enough to harrow before and after the first shoots.

In the second case, it is important to wait until the vetch and oats have up to three leaves, and the beans up to four.

Cutting green fertilizers is recommended at the flowering stage. By this period, the plants will have time to accumulate the maximum amount of nutrients necessary to enrich the soil.

Growing vetch-oat mixture for animal feed and silage

In addition to widespread use in agronomy, vetch-oat mixture is used in animal husbandry, both for sowing pastures and for preparing silage.

The mixture of these plants, when dried, is not as coarse as hay, and therefore is absorbed much better.

However, it is important to consider that, despite all the advantages, it has rather low nutritional values, it includes only:

  • Up to 20% dry matter;
  • 0.7% fat;
  • Up to 4% protein;
  • 45 mg carotene;
  • 6% fiber.

As in the case of fertilizers, it is recommended to cut the plants for silage in the budding phase, when vetch and oats have accumulated a sufficient amount of nutrients.

Vico-oat mixture is one of the most common examples of natural fertilizers.

An environmentally friendly and safe fertilizer, when used correctly, it is suitable as a fertilizer for cultivated plants and as a base for silage for animals.
