5 ways to deoxidize the garden

Sour soil in the garden - a problem faced by many owners of private houses and cottages. Since this is a favorite breeding ground exclusively for weeds, it is best for cultivated plants to have neutral and slightly acidic soils. But in vain you should not grieve. Normal liming will allow to deoxidize the land plot for several years. And how to do this folk remedies, we will talk later in our article.

The required pH level in the garden

There is a division into acidic, neutral and alkaline soils. The degree of acidity is determined by the pH icon:

  • very acidic - pH 3.8-4.0;
  • strongly acid - pH 4.1-4.5;
  • medium acidic - pH 4.6-5.0;
  • subacid - pH 5.1-5.5;
  • neutral - pH 5.6-6.9.

It is recommended to make soil liming after lowering the pH limit of 5.5.

What to do with high acidity

Soil deacidification or liming is the only way to reduce the acidity of the soil to the desired level. It is important to make compounds that contain lime.

This technique will reduce the acid balance of the land for several years. If the soil is heavier, this will last longer, if the light is less. Practice shows that deactivation is carried out on peat sites once every three years, on sand sands once every five years, and on loamy ones once every seven years. Moreover, with an increase in the content of humus in the soil, it is possible to increase the content of lime.

The correct soil Ph should not exceed 5.5

Liming the land

Experts advise to make the liming of the earth in several passes.

During the development of the garden or in the process of deep digging once a couple of years you need to make the bulk of lime in the form of fluff, slaked lime or chalk. Then the procedure is repeated annually, but the concentration of the compositions will be much less.

When the acidity of the garden is uneven, liming the soil can be done zonal - only for those crops that need normal acidity very much. Most often it is solanaceous. If the crop rotation is observed, the whole land plot will have to be processed.

Liming for planting fruit trees should be made a couple of years before. If we are talking about the garden and planting of cultivated plants, then in the fall.

Any composition for liming is scattered as evenly as possible over the site, and then digged up so that the substance is at a depth of 0.2 m from the surface. Moreover, the more uniform the location of the means for deoxidation, the better.

Sour Soil Liming

Application of hydrated lime on acidic soil

Slaked lime is considered an excellent deoxidizing agent. Quick in this situation is not suitable. Before applying the treatment of lime is extremely important to extinguish it with water. The amount of lime will depend on the level of acidity of the soil in the garden. So:

  • for very acidic soil will require 50-70 kg of fluff per one hundred square meters of land;
  • for medium acid soil - 40-45 kg;
  • slightly acidic area needs 20-25 kg of composition.

Use of dolomite flour

Before you buy this tool you need to pay attention to the degree of ground flour. Practice shows that the smaller the fraction of the composition, the sooner the desired effect will occur.

The best option would be limestone flour, the moisture content of which does not exceed 1.5%, and 2/3 of the composition of the grains vary in size of 0.25 mm.

If we compare the effectiveness of dolomite flour and hydrated lime, the first option, although it will take effect later, is absolutely safe from an environmental point of view. Plus, in this case there will be a simultaneous enrichment of the land plot with magnesium, calcium and other useful trace elements.

The concentration of the drug in 1 square. The garden area for highly oxidized soil is 0.5-0.6 kg, for medium acid - 0.45-0.5 kg, and for slightly acid soil - 0.35-0.4 kg. This information is necessarily indicated on the packaging of dolomite flour by the manufacturer.

Folk remedy wood ash

Wood ash is a great opportunity to reduce soil acidity. But in this case, there is no replenishment of calcium deficiency in the soil, which certain cultures badly need. This is especially true of the nightshade family.

Calcium deficiency causes top rot, which soon spreads, affects tomatoes and peppers. That is why experts advise the use of ash exclusively in combination with other compounds or preparations.

Spreading wood ash on acidic soil

When last year there was already a struggle with excess acidity, and this figure is uneven on the site, the ash will work fine. For re-deoxidation it can be used. In this case, per liter of water accounted for 0.2 kg of ash. This solution should be enough to handle 1 square. m of land.

When peat ash rather than wood is used, the concentration of the composition should be increased 1.5 times.

Mel as a deoxidizer in the country

Crushed chalk refers to calcium-containing compounds that allow to remove the acidity of the soil. It is important to note that the grains in diameter should not be more than one millimeter. Otherwise, the effect of liming will have to wait long.

For particularly acidic soil per 1 square. m is recommended to use about 0.3 kg of chalk, for medium acid - 0.2 kg, for weak acid - 0.1 kg.

After the chalk is evenly distributed over the plot, it is dug up, so the substance disintegrating will change the composition of the soil.

Mixing soil with chalk is a great way to reduce its acidity.

Use of siderates for deoxidation

On the shelves of shops you can find specialized products that allow to deoxidize the soil and at the same time fertilize it. Because they contain calcium, magnesium, phosphorus, boron, zinc, copper, manganese and other useful trace elements.

The main advantage of such funds is their environmental safety and grinding, which can not be doubted.

It is recommended to use the preparations in late autumn or spring before digging up by placing materials to a depth of 0.2 m. The reaction of the soil will become neutral in just a couple of years. In this case, after the distribution of green manure land is better to water.

Does the soil always need to reduce acidity

Soil deoxidation is not always necessary. First of all, it is when the pH level is within the normal range. And secondly, when cultivated plants planted on the site (for example, sorrel) prefer high acidity. From ornamental crops, this applies to rhododendrons, hydrangeas, ferns, silverweed, heathers, lupins, rhubarb, and even wild mint. As for the majority of vegetables, they prefer a slightly acidic and neutral soil rich in useful trace elements.

Preparation for determination of soil acidity

However, everything good should be in moderation and the use of a large amount of lime fertilizer can lead to an excess of calcium in the soil. As a result, root growth is hampered, especially when the root system of a plant is already weak. Plus, even abundant watering and rain will not wash away the calcium.

And then the desire to improve the soil will only lead to the emergence of new problems. This means that it is not worthwhile to strongly deoxidize the soil every year, you need to constantly check the pH level and only make lime on need.

In the process of soil deoxidation, several methods and means listed above can be used simultaneously, and they can even be grouped. It all depends on your wishes and the availability of available tools and materials. Difficulties in principle should not arise. The main thing is not to overdo it with the concentration of lime in the garden. Since their oversupply will adversely affect the cultivated plants that will grow there.
