Description

The invention relates to the field of land reclamation, soil, mainly peat, and is intended for use in agriculture and forestry. The known method of drainage amelioration, by which chemical drainage of heavy marshy soils is used. The closest to the technical extent to the proposed approach is a method of amelioration of soils, mainly peaty ones, including neutralization of the soil with lime, application of mineral fertilizers and microelements, as well as subsequent microbiological inoculation by applying bacterial culture of AMB and azotobacterin and mixing of the soil to the depth of the arable layer 2. However, this method does not provide high efficiency aelioration, as it does not allow to use the nutritional potential of peat. The purpose of the invention is to increase the efficiency of land reclamation. This is achieved due to the fact that according to the proposed method, including neutralization of soil with lime, application of mineral fertilizers and microelements, microbiological inoculation - introduction of the bacterial culture of AMB and azotobacterin with simultaneous removal of the soil to the depth of the arable layer, into the soil before the microbe, you and t bactericide. Moreover, as a bactericide, one-, two- or three-atom phenols are used, whether their mixture is and / and the mixture is preliminarily emulsified in the water of 70-100 ° C tars of technical oil and coaincTO and volatile distillation of fatty acids in a weight ratio of 1: 1: 1. In the case of using IB as a bactericide of a mixture of technical fat, soilstock and volatile distillate fatty acid distillation into the soil, aluminum chloride is added as a catalyst for aqueous ammonia to alkalify the medium in a 1: 1-3 ratio before microbiological inoculation. Example 1. Lime, nitrogen, phosphorus and potash fertilizers and microelements, as well as additionally one, two or three atom phenols or their mixture in equal weight ratios are uniformly introduced into the peat soil at the following dosages of the active substance, kg / ha:

Water soluble compounds are applied to the soil in the form of aqueous solutions.

Seal made to the colony: mpon "nte c. After the introduction of the indicated comonentists into the soil, after 15 days, after their work, microbiological

soil inoculation with an aqueous suspension of a bacterial culture of AMB and azotobacterin at the following dosages, kg / ha:

The soil is immediately mixed to the depth of the arable layer with components introduced into it, bacterial culture AMB and azotobacterin.

After these operations, the soil is suitable for the cultivation of agricultural and forest crops.

Oat seeds of the variety “Golden rain” are sown in the prepared soil, followed by embedding of seeds and rolling of peat lochva.

The techno-economic advantages of such an embodiment of the invention are given in Table one.

After performing these operations, oat seeds of the variety “Golden rain with subsequent seeding” and rolling of peat soil are sown in the soil.
