Why do you need crop rotation?
The basic rule of any crop rotation: types from one family of plants should not grow one by one in the same place.
Benefits of crop rotation:
- reduces the risk of infection by pathogens;
- reduces weed pressure;
- The nutrients contained in the soil are optimally used;
- Soil enrichment by humus, which keeps her fertility for a long time.
It is important not only spatial diversity, but also a variety of cultivation over the years.
Vegetable crop rotor
Please note!In the limited space of small gardens, it is recommended to change plants every year.
From different layers of soil, each type of plants receives a different combination of nutrients. This allows them to more evenly use nutrients. A competently planned sowing procedure will significantly save on artificial fertilizers. If you include in the process of sowing the right cultures, you can save moisture in the soil.
The incidence of diseases, weeds and pests is reduced. Crowning will create them obstacles, will not allow them to arise massively.
Alternation of crops
Crowning can prevent all types of erosion: aquatic, wind and chemical-biological. The use of the right sowing methods improves the quality of the soil, which plays a key role in obtaining good yields.
crop rotation in the garden, after which you can plant? Mixed planting of plants on tired soils
Mixed culture prevents soil fatigue. Plants with different characteristics and needs are cultivated mutually beneficial. Growing plants with a mixed way to benefit each other, increases soil fertility. It also looks very colorful.
Mixed landing prevents diseases and fungi to penetrate into the rows, so plants remain healthier. Different types of plants help each other.
If we plant the right partners together, the nutrient reserves are better used in the soil, because each plant uses different nutrients from different deep layers of the soil. In addition, the disease or fungus cannot spread so easily, and they can be better restrained.
Fragrant herbs
Fragrances or root allocations of some herbs scare pests and, thus, help adjacent plants.
Important! Exists that some types of plants do not harmonize with each other, and their immediate vicinity should be avoided.
Soil enrichment with nitrogen
Nitrogen is a chemical element necessary for the healthy development of plants. It is not enough in soils, therefore supply nitrogen with artificial fertilizers.
Different cultures have different nutrient needs and affect the soil balance in different ways. Some of them, such as corn and tomatoes, quickly deplete soil nitrogen and phosphorus. If corn is growing year after year in the same place, this soil will have a lower nitrogen and phosphorus content. By annually changing the landing site, it is possible to restore the soil on which culture grew last year. Including in the process of sowing legumes (peas, soybeans, beans), you can make nitrogen into the soil naturally from the air.
Pobov representatives
Most of the necessary nitrogen falls into the soil during the cultivation of legumes. Bean cultures can bind atmospheric nitrogen using nodule bacteria in roots, and thus most of the necessary nitrogen is available. In addition, some of the remains of plants and roots leave a large amount of nitrogen.
Cultures that quickly use nitrogen are leafy and fruitful cultures, such as salad, cabbage and tomatoes. On the contrary, root roots and herbs do not need nitrogen and phosphorus (or only in very small quantities). Peas, beans and other legumes are added to the soil of nitrogen, but it takes a lot of phosphorus.
Related Cultures
To get a good harvest, you should carefully choose the plants next to each other, because not everyone gets along with everyone.
So that the soil is not leached, fungi and pests did not develop, and to extract the maximum of the soil, the crop rotation in the garden has the meaning. Useful Siderates in the fourth and last year of crop rotten to bed. Important nutrients. Thus, you can achieve the best crops with less use of fertilizers.
Cultures as the fruit and production of fruits are removed from the soil a large number of available nutrients. These include most fruit plants, tomatoes, eggplants, pumpkin, as well as leaf vegetables, such as cabbage, broccoli and cauliflower.
Additional information! To cultures worsening the state of the soil include grain and root corrupts. Cultures, improving the state of the soil – bean, clover and mixtures.
The last stage of the alternation of plants should be legumes. They return to the soil of nitrogen from the air. These include all kinds of beans and peas, as well as clover. In addition, the green residues of these plants can be plowed in the soil as an organic green fertilizer.
The share of major leguminous crops in crop rotation should be from 20 to 30 percent. Especially suitable feed beans in the mixture with herbs. They have a strong influence on the yield of subsequent cultures and have a stronger effect of weed suppression.
However, the recommended breaks in their cultivation should be observed. Some pathogens affect various types of legumes, therefore, these cultures require appropriate cultivation breaks. Studies show that longer breaks in the cultivation of legumes lead to a smaller number of diseases and, thus, to an increase in yield.
Next year, it is possible to plant roots, such as carrots, radishes, beets. After plant rich in nutrients, rootes do not require a large amount of nutrients for their growth and maturation.
Parenic Family Vegetables
Another major principle of crop rotation is that plants from one family should not be grown in the same place two seasons in a row. The families of the same or very similar plants have some need for nutrients from the soil.
Not all plants of one family love each other in the garden. Repeated sowing of these crops in the same place causes one-sided exhaustion of the soil:
- Parenic Family Cultures include tomatoes, peppers, eggplants, potatoes
- Kaping family includes crops such as broccoli, cabbage, cabbage, cauliflower, Brussels cabbage;
- Plants of the Pumpkin Family include cucumbers, melons, pumpkins;
- Pink plants – such as strawberries, raspberries, apples;
- umbrella – such as dill, kerwell, cumin or fennel;
- Carrots, Celery and many herbs enter the carrot family.
In addition to the needs of plants in nutrients, it is also necessary to take into account that common diseases and pests are usually observed in nearby cultures.
Nutrient Balance in Soil
The general rule is to prevent landing of the same culture in the same place. It is better to alternate bean, producing nitrogen, with loving nitrogen vegetables, such as salad or tomatoes.
Also alternate crops from the point of view of their influence on the pH of the soil. Peas, flax and potatoes acidify the soil. In an acidic environment, very many vegetable and garden-berry cultures cannot grow. The acidity of the soil affects the absorption of nutrient plants.
Do not grow cultures affecting the same diseases that are attacked by the same pests.
Do not grow one after another culture, which allow developing the same weeds. Frequent crop rotations not only prevent the appearance of pathogenic microorganisms, but also reduce the growth of weeds.
