Basic rules of crop rotation

Cultures that suffer from the same diseases can not be consistently grown at the same place, affected by the same pests and leaving them behind in the soil. Usually such crops belong to the same botanical family.

Vegetables from one family should not follow one another in the same bed in either a small one( during the season) or in a large crop rotation.

The sequence of crop locations should also take into account their impact on the soil. Some species are loosened by its roots, enriched with organic substances and nitrogen, others are condensed and depleted.

Cultures with strong and weak nutrient intake should be alternated to avoid unilateral depletion of the soil.

It is useful to alternate crops with deep and shallow roots, then the first can get their food from deeper horizons.

Beans must be included in the crop rotation, as they enrich the soil with nitrogen.

The more time passes before re-cultivation of crops in the old place, the better.

The main culture with a long maturation period can be returned to the same bed not earlier than in 3 years. For carrots, beets, peas, cucumbers and parsley this term increases, as they react poorly to their own root extracts, accumulating in the soil.

The main culture can be returned to the former bed earlier, if after it will be sown sideral crops.

9632;On fertilized compost or overgrown manure, it is advisable to grow crops characterized by a high intake of nutrients in the first year: all kinds of cabbage, celery, leeks, cucumbers and tomatoes, and less demanding crops - root crops, onions,beans.

The following year, after intensive fertilization of the bed and the cultivation of strong nutritional consumers on it, legumes or less demanding plants can be planted on it.

raquo;To maintain the fertility of the soil at a constant level, alternation of crops and the introduction of organic and mineral fertilizers are necessary.

It is very important to properly organize crop fertilization in crop rotation. Not all vegetable crops respond equally to fertilizers.

Crop rotation mechanics

The site allocated for the garden is conditionally divided into 2,3 or 4 parts. Part of the site, designed to grow strong consumers of nutrients, is well fertilized. The following year, medium or weak nutrient users are planted on the fertilized part of the site without additional fertilizer application

This is why it is recommended that those vegetables that have much in common in the system of fertilizers and protective measures be placed on a garden plot near them. For example, after applying manure to the soil, it is better to grow cucumbers, cabbage, pumpkin, lettuce, zucchini. In the second year after the application - potatoes, tomatoes, onion radish, beetroot, carrots. The third or fourth - legumes. Therefore, in the first year only mineral fertilizers are applied to potatoes. Lime is better to make on a site where cabbage will be placed.
