Liming the soil in the garden, why, when and how this should be done?

The growth and normal development of the fruit andvegetable plants depends on the composition of the soil. Particular influence the level of acidity. In this figure the soil is divided into three groups: acidic, neutral and alkaline. For many horticultural crops represent the greatest danger of the soil with a high level of acidity. In plants, developing in such conditions, we can see a clear slowdown in growth due to poor digestibility of nutrients contained in acidic soils. Periodic liming the soil allows you to align the acid-alkaline balance, thereby eliminating the cause, depressing the growth of plants.


On what grounds reveal acidic soil?

On the need for deoxidation of soil can be foundboth in their appearance and on the results of laboratory tests. To conduct soil liming immediately necessary in the event that the land at the site found a whitish or grayish-white shade. On the acidity of the soil and tells of 10-centimeter-podzolic horizon. The growth of weeds may also be an indicator of excessive oxidation of garden soil. The color of litmus indicator, descended into the diluted water samples of soil, you can see the form of the soil.

Accurate and quick way to measure the acidity in soils

Device - PH-meter, which allows the grower to determine quickly and accurately the level of acidity of the soil in different parts of your garden or backyard

If you want to know the exact degree of acidity of the soil, then hand over its samples for analysis in the agrochemical laboratory.

What substances contribute to the acidic soil?

Most often liming acidic soils performed using slaked lime. When calculating the necessary quantity of the substance taken into account:

  • composition of the soil in the garden area;
  • ground level of acidity;
  • the estimated depth of the seal.

At high pH (pH5 or below) in soilmaking large doses of lime. For every square meter of clay and loamy earth is added at least 0.5 kg of limestone and sand - 0.3 kg. With an average level of soil acidity reduces the dose, respectively, to 0.3 kg and 0.2 kg. In sandy soils with calcareous materials are added to a weak level of acidity, and in clay and loamy earth enough to make 0.2 kg per square meter.

No less common in gardeners and methodliming wood ash containing up to 35% calcium. The wood ash is present phosphorus, potassium and other trace elements that are beneficial for plant growth.

Application rate of lime to the deoxidation of different types of soil

Application rate of lime, indicated in kilograms per ten square meters, with different types of liming acid soils on a garden site

Also, lime and gypsum soil is carried out by the lake lime (drywall), chalk, peat ash, dolomite, lime-fluff, etc..

Optimal timing of lime

It is recommended at the stage of garden favorites spendingInitial activities liming site. It is advisable to carry out liming area in autumn, making the limestone with organic fertilizer to the ground digging. digging site allows not to leave made substances on the ground surface. If such events scheduled in the spring, then perform them for three weeks before planting vegetables. Allowed liming of the soil and in the winter, while the dolomite flour crumbles directly on top of the snow. The thickness of the snow cover should not exceed 30 cm. It is not necessary to make lime with manure, since they interact to form insoluble compounds.

Under such vegetables as beets and cabbage,make lime material should be directly in the crop year. By crop rotation other vegetables planted in the garden limed areas until the next year. Liming area used continuously for growing potatoes, carried out in the autumn.

Basic and re-liming

During the main (reclamation)liming of the soil having a high acidity, make full doses of materials that enhance the value of pH to a predetermined value. The aim of the re (support) of liming is to keep the soil at the site of the optimal level of environmental response. At the same time the introduction of small doses of calcium fertilizers compensates for the loss of the land lime, occurred during the season.

lime flour

Lime flour allows to increase the level of acidity of the soil to the desired parameter with the needs of cultivated crops on the site

As a result of the liming site fails:

  • to strengthen the livelihoods of a number of beneficial microorganisms (nodule bacteria, etc.);
  • enrich soil nutrients available for garden plants;
  • improve the physical properties of the soil (water permeability, structure and others.);
  • improve mineral and organic fertilizers by 30-40%;
  • decrease in farmed production of toxic elements (especially true for garden plots, located near industrial areas).

So, to eliminate the excess acidity problemliming the soil allows it. Contributed lime fertilizers have a beneficial effect on the growth, development and productivity of cultivated in the area of ​​agricultural crops. It increases the impact of the costs incurred by the gardener for the purchase of mineral and organic fertilizers. On neutral ground slows down the process of accumulation in fruits and berries of harmful substances. Liming section allows you to build an environmentally friendly crop.
