Advice 1: How to acidify soil

Depending on the mineral and chemical composition, the soil can be neutral, acidic and alkaline. The acidity is characterized by pH. On neutral soil pH=7. What this indicator is lower, the more acidic the soil.
How to acidify soil
Instruction
1
Many ornamental plants prefer acid soil: rhododendron, Gardenia, gorse, violet. Srednekislye soil suitable raspberries, strawberries, gooseberries, potatoes, cabbage. To acidify the soil, populate it with rotted pine needles, or sawdust of coniferous trees and alder as fertilizer.
2
Needles, sawdust and bark can be used as mulch. Fresh sawdust is pulled from the soil nitrogen. If you decide to use them, add under plants nitrogenous fertilizer, so as not to impoverish the land. As mulch also drink weak tea and coffee. Not only do they retain moisture and fertilize the soil, but also protect the plants from slugs.
3
Add to water for irrigation oxalic or citric acid (2 tablespoons per bucket of water) and Apple or wine vinegar (100 g per bucket). You can acidify the water with sulfuric acid or a new unused electrolyte for batteries. You need to keep in mind that the concentration of sulfuric acid included in the composition of the electrolyte depends on its density. Colloidal sulfur can also be used as the oxidant.
4
For household plants in specialized stores sell fertilized soil with the proper mineral composition and the desired pH level. But if you use the common land, which was gained in the country or in the woods, for acidification, you can add a few drops of lemon juice.
5
Good aqueous extract of the peels of lemon. To use at home, weak tea and coffee are not recommended because they can become food for the Drosophila, or fruit flies.
6
To determine the acidity of the soil in different ways. The most reliable household pH meter, different models which are sold in specialized stores.
7
A good indicator of the acidity will be currant or cherry leaves. Pour 3-4 leaf Cup boiling water. When the infusion has cooled, throw a pinch of the earth. If the soil is acidic, the water will turn red if acidic – it will turn blue. Green – the indicator is slightly alkaline or neutral environment.

Advice 2 : How to neutralize soil acidity

One of the most important parameters of soil is the pH level - the acid-alkaline balance. The optimum acidity of the soil the plants grow in the best way. Saturation of the soil acid salts allows you to absorb the nutrients, so you need to take action to reduce the level of acidity.
How to neutralize soil acidity
Instruction
1
Different cultures have their preferences on the level of soil acidity. Most plants grow well in soils with a pH from 6.2 to 7.5. It is a neutral or close to neutral values. The plants, well grown on these soils include cabbage, beets, peas, celery, cucumber, lettuce, onions, parsley, carrots and turnips.
2
In slightly acidic soils with a pH of 6 it is advisable to grow beans, fennel, tomato, eggplant, corn, melon, squash, horseradish, spinach, radishes and rhubarb. Srednekislye on 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 vegetable crops.
3
The development of plants in acidic soils is incomplete, since the nutrients are in unavailable form. In soils with high acidity actively breed bacteria and pests. Soil-forming bacteria in these soils are virtually absent.
4
To determine the acidity of the soil, you can use several methods. The most affordable method is the use of litmus paper in accordance with the instructions. If possible, you can order a soil analysis in agrochemical laboratory.
5
When there is no possibility to analyse litmus paper or in the lab, we can determine the approximate pH of the soil around the weeds grown in the area. On highly acidic soils and prefer to grow horsetail, Ivan-da-Marya, plantain, sorrel, sorrel. On the medium to slightly acid soils grow Wheatgrass, clover, mother and stepmother, violet dog.
6
To reduce soil acidity liming is applied. Slaked lime is introduced on highly acidic soils 50-75 kg per 100 square meters srednekislye 40-45 kg per 100 sq m, slightly acidic 25-35 kg per 100 sq. m.
7
Slaked lime can be replaced with dolomite flour. The deoxidation of the soil will take longer, but dolomite powder contains useful minerals. Application rate - from 300 g to 1 kg per sq. m.
8
To reduce the acidity of the soil used ash containing a large amount of potassium and phosphorus. The ashes made in the amount of 100-200 g per 1 sq. m.
9
The use of green manure is another way to reduce the acidity of the soil. To sow green manure several times per season. For green manure, decreasing the acidity of the soil are rye, vetch, phacelia, oats, lupins and beans.
10
Applying measures to deoxidation of the soil in the complex, you can achieve faster results. For example, in autumn the site can be make dolomite powder. The spring under perekopku add ash. During the vegetative season, sowing of green manure. The reaction the pH of the soil will be close to neutral in about 2-3 years.
