The problem of acidity of the soil is relevant for many summer residents. The problem is that the sour earth is less fertile, than neutral. How to define what view of the soil on the site? Whether in it the reason of poor harvests of vegetables? What is the sour soil and as it is possible to deoxidate it?
Instruction
1. First of all to roverta the soil on acidity. The most widespread way of check - litmus paper which is on sale in various shops for gardeners. For determination of acidity take soil sample from depth of 20 cm. There will be enough also 100 g of the soil from the checked site. Then moisten with clear water (rain, distilled, boiled). Squeeze soil sample together with litmus piece of paper in hand. If the piece of paper was painted in red color - the soil silnokisly. Pink color – the soil has average acidity. The subacidic soil will paint in yellow color. The neutral soil will be shown by blue color. If color has greenish-blue shade - the soil is close to neutral. Also it is possible to determine acidity of the soil by weeds and wild-growing plants. On silnokisly soils the velvety green raid - moss usually appears. On sour - field horsetail, horse sorrel, wild mint, three-colored violet. On subacidic the camomile, dandelion, coltsfoot, goutweed, clover, wheat grass, ferns grow. The shepherd's bag, nettle, wood louse, orach - these weeds specify that the soil is neutral. On alkalescent soils the bindweed, poppy, sleepiness white grow. There is still easy way to learn acidity of the soil. It is necessary to put several leaves of cherry or blackcurrant in glasswares. To make leaves boiled water. When water cools down, throw into ware of a little checked earth. If water becomes red color - the soil on the site acidic. If blue – subacidic, and if greenish shade - neutral.
2. Raskisleny soils or lime application are process of entering into the earth of limy fertilizers. Entering of lime into the soil not only reduces its acidity, but also improves structure, reduces quantity of weeds, stirs up activity of useful microorganisms. The more small limestone is ground, the stronger and action is more notable than it. For softer influence instead of lime it is possible to use chalk.
3. To raskisleniye of the soil it is widely applied also dolomitic (limestone powder) which at the same time is also valuable limy fertilizer. Dolomite powder neutralizes and levels acidity of the soil and also enriches it with magnesium, potassium and other microelements, useful to plants. Pay attention that dolomite powder and lime cannot be mixed with ammonium sulfate, ammonium nitrate, urea, superphosphate simple and granulated.
4. Also good effect gives use of marl (muddy material), swept-rukhlyaka. These are types of friable calcareous rocks. It is possible to apply to raskisleniye of the soil also wood ashes. But consider that use of ashes is justified when it is necessary to correct acidity only a little.
