Different cultures have their own preferences in terms of soil acidity.Most plants grow well on soils with a pH of 6.2 to 7.5.It is neutral or close to neutral values.The plants, which grow well on these soils include cabbage, beets, peas, celery, cucumber, lettuce, onions, parsley, carrots and turnips.
In slightly acidic soil with a pH of 6 is desirable to grow the beans, fennel, tomato, eggplant, corn, melons, squash, horse-radish, spinach, radishes and rhubarb.In a mildly soils with a pH of 5 to 6 can grow potatoes, peppers, sorrel, beans, parsnips and pumpkin.On soils with a pH below 5 do not grow all the vegetables.
development of plants on acid soils defective, since nutrients are n
ot available form.In soils with high acidity are actively multiplying bacteria and pests.Soil-forming bacteria such soils are virtually absent.
To determine the acidity of the soil, you can use several methods.The most affordable method - the use of litmus paper in accordance with the instructions.If possible, you can order analysis of the soil in the agrochemical laboratory.
In the absence of an analysis of litmus paper, or in the laboratory, we can determine a rough indicator of soil acidity on the weeds growing in the area.In highly acidic soils, it prefers to grow horsetail, willow-wheat, plantain, horse sorrel, Oxalis.In the medium and slightly acidic soils grow couch grass, clover, mother and stepmother, Violet dog.
To reduce the acidity of the soil applied lime.Hydrated lime is introduced in the highly acidic soils of 50-75 kg per 100 square meters, on a mildly 40-45 kg per 100 square meters, in the slightly acidic range 25-35 kg per 100 square meters
hydrated lime can be replaced by dolomite flour.Deoxidation of the soil will take longer, but dolomite flour contains useful minerals.Application rate - from 300 g to 1 kg per sq.m.
To reduce the acidity of the soil using ash containing a large amount of potassium and phosphorus.The ash is made in an amount of 100-200 g per 1 sq.m.
Use of green manure - another way to reduce the acidity of the soil.Sow green manure should be several times per season.For green manure, lowering the acidity of the soil, are rye, vetch, Phacelia, oats, beans and lupins.
Applying measures for soil deoxidation in the complex, you can achieve faster results.For example, the fall in the area can make dolomite flour.By digging in the spring to add ashes.During the growing season to sow green manure.Reaction pH of the soil will be close to neutral after about 2-3 years.
