The reason for poor yields is acid soil. What to do for the fertility of the earth?
The acidity of the soil can be determined independently, without resorting to the service of the agrochemical laboratory. To determine the exact pH of the soil, use a set of litmus paper. There is a simple experience. In the milk baby bottle with divisions fill up the sieved soil to the level of the second strip, pour water to the fifth division and pour out 1/2 teaspoon of chalk powder. And immediately pull on the neck of the rubber nipple, pre-tightly rolled it. Wrap the bottle with a newspaper and shake for five minutes. From the reaction of chalk with the acids of the soil, carbon dioxide will be released, creating a pressure. If the acidity of the soil is weak, then the twisted nipple will straighten slightly, and with strong acidity it will inflate. There are also visual methods that are less precise. Weeds on acid soils tell about the level of its acidity. Slightly acidic soils suggest such indicator plants as creeper grass, dandelion, white clover, birdwort, scallop, chamomile chamomile, buttercup creeping. On srednekislyh grow violet tricolor, clover grazed, plantain, wild sorrel, wild mint. Strongly acidic soils are covered with horsetail, cotton grass, cat's foot, small spaghetti. If in spring the land lot does not dry out, and then dries very quickly and becomes covered with crust, this indicates that there is acid soil.
Reduces the acidity of the soil liming. For this lime-puschka, which is applied in spring and autumn before plowing, is suitable. You can replace lime with ground chalk, wood ash, marl. Before liming, find out in the reference books about the permissible and sufficient doses of introducing a substance, so that in the process of liming from acidic soils they do not turn into alkaline soils. It should be noted that liming is not carried out:
- simultaneously with the introduction of manure (lime will destroy nitrogen in it);
- simultaneously with phosphorite flour (phosphorus will pass into insoluble);
- before planting carrots, tomatoes, pumpkins, cucumbers, beans, celery, parsley, potatoes (strong scab on tubers).
The introduction of mineral fertilizers is necessary for the fertility of crops and where there is acid soil. What should I do to increase the yield? We shall name the most effective and permissible fertilizers for acidic soil. Of nitrogenous it is nitrate: sodium and calcium. Do not use ammonium nitrate and urea - they acidify the soil. Of phosphoric, use precipitate. Of the potash - potassium sulfate, wood ash (it should be stored in a dry room).
