To obtain a good harvest of potatoes, it is necessary to monitor the condition of the soil and fertilize it in time. Modern industry produces for this purpose a large amount of chemical fertilizers, only after their use, the crop will no longer be environmentally friendly and safe. In order to enrich the soil with useful substances and increase its fertility, but at the same time not to conflict with the ecology, it is necessary to sow the green manure in the section between the green manure.

Why do we need green manures for
potatoes Green manure are natural fertilizers .After their landing, the soil is plowed up, as a result of which the green mass is in the ground. There it begins to decompose, resulting in the release of useful micro and macro elements.
In addition, the top layer will be enriched with the necessary elements for potatoes:
- phosphorus and others.
It is necessary for to control the volume of growing green , because if there is a lot of it, souring of plowed vegetation will take place. This can lead to the multiplication of pathogens.
Siderats not only fertilize the soil and fill it with essential nutrients. They also help get rid of the most common diseases and pests that affect potatoes.
How to prepare the soil
Green manure, like any crop, requires preliminary soil preparation before planting. After harvesting, the land is smoothed with a rake or other tool, and the is put in a nitroammofosk ( at the rate of 10 liters per hundred square meters).
If the acidity of the soil is high, then you can add a little lime .Strongly dry ground must be watered before planting siderats. For these purposes it is better to use a shower head. Only after that you can proceed directly to the sowing of seeds and their embedding.
How to apply
The time for planting green manure is selected depending on the purpose for which they are applied to the site. If plants are designed to repel pests, then seeds can be sown directly in the aisle of .In this case, you will need to periodically cut them, to prevent the seeds from ripening.
They must be quite cold-resistant, because by the time the potatoes are planted, these plants are already cut. Autumn sowing involves treating the soil and enriching it with useful microelements for the future season. All necessary measures are carried out after the harvest has been gathered and the site is completely free.
Why do they make
in spring? When sowing siderarates in spring, potatoes will gradually receive nutrients from their decomposition over the entire growth period.
Sowing is done immediately, as soon as the snow comes off and the earth begins to warm up. Cultures must be cold resistant.
In the spring, it is very good to sow such plants as:
It is also possible to use siderats, which will grow simultaneously with potatoes, enrich the soil and deter pests.
They may be:
- leguminous plants;
Is it possible to plant
Autumn sowing of siderats will not only fertilize the land, but also to suppress weeds, to help saturate the soil with oxygen, to reduce the number of pests.
When calculating planting dates, it is necessary to think that before the onset of frost, crops should have time not only to rise, but also to grow. Otherwise they cannot be used as fertilizers.
Most often, the following plants are used as autumn green mans for potatoes:
is especially valued for white mustard , because it has the ability to grow rapidly even at low temperatures. But oats can later not be cut, and planted potatoes directly into it. The dried plant in this case will serve as mulch and protect the crop from the negative impact of the external environment.
How to choose
A key criterion when choosing green manure for potatoes is the general condition of the soil. It should be loose, with a sufficient amount of mineral substances, without pests and diseases.
Unfortunately, one type of plant is often not able to solve all the problems. For this, combinations of several plants are used.
In order to increase the fertility of the soil and its fertilizers, legumes are planted at the growing site of potatoes. They relieve gardeners of the need to use fertilizers of inorganic origin and saturate the earth with all the necessary trace elements.
mustard or colza helps well in pest control( wireworm, late blight).But to scare the Colorado potato beetle is good to plant flax.
Siderats also help to cope with the main weeds. For this purpose, buckwheat, nasturtium, radish, clover, and alfalfa should be sown on the plot .
What kind of green manure is better for potatoes
However, there is also a universal option - phacelia .It is frost resistant, quickly gaining green mass and is able to provide the soil with good breathability. That is why this plant has gained immense popularity among gardeners.
Is it possible to plant if the soil is infected with pests or the fungus
In no case should potatoes be planted in contaminated or diseased land. Before landing, such a section should be treated .DO NOT rush and resort to chemical treatment. Siderats can come to the rescue.
Natural healers can serve:
- oilseed radish;
- mustard white;
These plants not only treat the soil, but also eliminate the pests that are in it. In particularly contaminated areas, seedlings can be left between the rows. Thus, the phytosanitary will perform their work throughout the season.
Types for potatoes
Legally, legumes are considered to be one of the best green manure, which have the ability to saturate the soil with useful microelements.
It is worth paying attention to Vika .It is a curly annual, which not only prevents soil erosion, but also significantly improves its structure. Well proven in neutral soils.
Such a plant as sweet clover can not only improve the structure of the soil on the site, but also help in the fight against the nematode and wireworm. Thanks to a powerful and extensive root system, it has the ability to extract useful substances from the very depths of the earth.
Cruciferous are used not only as a natural fertilizer, but also as means for treating the .They help in the fight against viruses and pests.
The most common in this group is white mustard .It tends not only to quickly build up the green mass, but also to loosen the earth, improve its structure. After mowing, it is an excellent fertilizer, and in the process of growth protects the area from weeds.
deserves no less attention radish .Thanks to a powerful root, the plant loosens the soil well, helps retain moisture, destroys pathogenic microbes, and fights fungal diseases well. It tends to inhibit weeds. When decomposed, it forms a large amount of nutrients.
Rye attracts the attention of gardeners due to its cheap seed and low soil requirements. When decomposed, it forms a large amount of organic fertilizer, but cannot fix nitrogen in the soil.
If you use as oats as a green fertilizer, you can replace 200 kg of manure per one weave with one of its crops. This plant is able to improve the soil structure, helps in the fight against weeds, nematodes, fungal diseases, scab, root rot.
Can phacelia be siderae
Phacelia has a very short ripening period .The plant loosens the soil well, while decomposing it enriches it with nitrogen, potassium and phosphorus, and is able to inhibit the growth of weeds.
Thanks to these properties, the plant is widely used as a siderata. It tolerates frost fairly well, which makes it possible to get several harvests per season. Green mass can also be used as animal feed.
Pros and cons
Siderata among gardeners called green fertilizer. This is no accident: these plants when plowing into the ground act like manure, peat or other organic fertilizers. When they decompose, a lot of useful micro and macro elements are formed, which are so necessary for the full growth and development of potatoes.
Some green manure can not only fertilize, but also heal the soil, and also scare away the most common types of pests.
There are probably no negative aspects of using such fertilizers. Except for the fact that the process of their cultivation itself requires some material costs and the investment of its own forces, labor. Yes, and the growth process takes some time, so you need to be patient and wait until the green mass increases.
When using green manure for potatoes, it is possible not only to increase the yield of the plot, but also to grow an environmentally friendly product .After all, natural fertilizers are absolutely safe for the human body, which is not the case with chemical analogues.
