The harvest directly depends on quality of the soil, one of indicators of which is the acidity. If the earth sour, then at cultural plants poorly develops root system, and they badly acquire nutrients.
The high acidity generates substances, harmful to garden and garden cultures, in the soil, kills useful bacteria which process manure, peat and compost into nutritious form, digestible for plants. In the sour soil the carbohydrate and proteinaceous exchange of cultural plants is broken, the harvest up to full death of landings decreases. Contrast to sour soils – alkaline, also of little use for plodordiya. The nature has disposed so that the vast majority of cultural plants best of all develop on neutral, alkalescent and subacidic soils. Therefore to the one who wants that everything blossomed on its site and eared, it is just necessary to know the level of acidity of the earth. It is the best of all to define it by the analysis in agrochemical laboratory, but if there is no such opportunity, that is sense to resort to national methods. It is necessary to put several leaves of cherry or blackcurrant in glasswares. To fill in with glass of boiled water, to wait until it cools down and to throw into it earth lump. If solution becomes red – on the site the sour soil, the blue means weak acidity, the neutral soil will paint solution in green color. The whitish layer, similar to ashes, in arable layer of the earth also speaks about acidic environment. If experiments have shown high acidity, then its level needs to be reduced for what there is the unique way – lime application. One of the most valuable limy materials are oven ashes. In comparison with peat it contains twice more calcium and, besides, she on herself is excellent fertilizer, phosphorus rich with potassium and number of microelements. Sandy, sandy and peat soils sour and poor in potassium best of all react to oven ashes. From other materials also unslaked lime, chalk, cement dust are most often applied to lime application extinguished. At the same time it is necessary to remember that the key to success is in uniform distribution of lime in the soil and careful hashing with it.
