One of the most important parameters of the soil is the pH level - acid-base balance. At optimum acidity of the soil of a plant develop in the best way. Soil saturation sour salts does not allow to acquire to plants nutrients therefore it is necessary to take measures for decrease in level of acidity.
Instruction
1. Different cultures have the preferences on the level of acidity of the soil. The majority of plants well grow on soils with indicators of pH from 6.2 to 7.5. These are neutral or close to neutral values. Cabbage, beet, peas, a celery, a cucumber, salad, onions, parsley, carrots and turnip belong to the plants which are well growing on such soils.
2. On subacidic soil with an indicator of pH 6 it is desirable to grow up haricot, fennel, a tomato, an eggplant, corn, a melon, a squash, horse-radish, spinach, a garden radish and a rhubarb. On srednekisly soils with an indicator of pH from 5 to 6 potatoes, pepper, a sorrel, beans, a parsnip and pumpkin can grow. On soils with an indicator pH lower than 5 all vegetable cultures badly grow.
3. Development of plants on sour soils defective as nutrients are in an inaccessible form. In soil with the increased acidity pathogenic bacteria and wreckers actively breed. Pochvoobrazuyushchy bacteria in such soils are practically absent.
4. For determination of acidity of the soil it is possible to use several methods. The most available method – use of litmus paper according to the instruction. If there is an opportunity, it is possible to order the analysis of the soil in agrochemical laboratory.
5. In the absence of an opportunity to carry out the analysis by litmus paper or to laboratories, it is possible to determine an approximate indicator of acidity of the soil by the weeds growing on the site. On silnokisly soils prefer to grow a horsetail field, Ivan - yes - Marya, a plantain, a horse sorrel, a kislitsa. On average and subacidic soils a wheat grass creeping, the clover, coltsfoot, a violet dog grow.
6. Lime application is applied to reduction of acidity of the soil. Extinguished lime is brought on silnokisly soils of 50-75 kg on 100 sq.m, on srednekisly 40-45 kg on 100 sq.m, on subacidic 25-35 kg on 100 sq.m.
7. Extinguished lime can be replaced with dolomite powder. Raskisleny soils will longer occur, but dolomite powder contains useful minerals. Norm of introduction - from 300 g to 1 kg on sq.m.
8. For decrease in acidity of the soil the ashes containing potassium and phosphorus in a large number are used. Ashes are brought in number of 100-200 g on 1 sq.m.
9. Application of siderat – one more way to reduce acidity of the soil. It is necessary to sow siderata several times during the season. A rye, Vika, the fatseliya, oats, a lupine and bean belong to the siderata lowering acidity of the soil.
10. Taking measures for a soil raskisleniye in a complex, it is possible to achieve faster results. For example, in the fall on the site it is possible to bring dolomite powder. Under spring redigging to add ashes. During the vegetative season to make crops of siderat. Reaction of pH of the soil will become close to neutral approximately in 2-3 years.
