Description

eleven

The invention relates to agriculture and can be used in the intensification of agricultural plants on easily drained sandy and sandy soils.

The known method of reclamation of sandy and sandy soils, including the creation of a layer based on an aqueous suspension of organic components with the addition of surfactants in the following ratio of components, wt.%;

Clay40.00-50.00

Liquid manure 18,00-20,00 Low-grade

phosphate 12.00-15.00 Surfactants0, 10-0.15 Clinoptilolite 5.00-8.00 Water Else. which is laid 2-A cm thick in the subsoil horizon J.

The disadvantage of this method is the fragility of the interlayer due to the rapid mineralization of the organic component - manure, and also that the interlayer does not allow sufficiently to reduce the loss of nutrients from the soil.

There is also known a method of reclamation of sandy and sandy soils, including the creation of a layer based on an aqueous suspension of organic components with the addition of surface-active substances in the following ratio of components, wt.%:

Water 20,000-22,000

Il8,000-12,000

Silicone0,001-0,010

Sand Else, the interlayer being made with a thickness of 0.5-1.5 cm 2.

The disadvantage of this method is the difficulty of creating an optimal water-physical regime of sandy and sandy soils in the cultivation of fruit crops, including grapes, which leads to the death of the seedlings due to the soaking of the root system due to water stagnation.

5609. 2

The purpose of the invention is to improve the water-physical regime of the soil and reduce the loss of nutrients from the soil during the reprocessing of plants. 5 The goal is achieved by the method, which includes the creation in the subsoil horizon of a layer based on an aqueous suspension of organic components with

0 by the addition of surfactants, peat and loam are used as organomineral components, sodium tripolyphosphate and Vox Voximetilcellulose sodium as polymers, and additionally aerosil at the following components, wt.%:

The layer is thick, 45 cm thick at a depth of 35-40 cm.

.Example. In an open pit excavator bucket mix the mixture

0 wt.%: Peat 63, loam (light mechanical composition with a particle content of 0.001 mm 8-13%) 21, sodium tripolyphosphate (TPPN, GOST 13455-63) 1.5 10, carboxymethylcellulose

5 (iMJi) 4-10 aerosil 6-10 and water the rest up to 100, - until a homogeneous paste is obtained.

A layer of 35 cm is removed from the previously prepared surface of the furnace.

0 then, using a trailed manure spreader, the paste is placed with a thickness of 4.5 cm, the resulting layer is applied to the previously removed soil layer. Fertilizer is applied to the topsoil.

quantity, kg / ha: N 180, R.120, K 120 of the active substance - and grape seedlings are seen. Then control the amount of NPK fertilizers washed out with simultaneous determination of the filtration coefficient. The results of the experiment are presented in the table (the effect of the composition and thickness of the screen on the water-physical soil regime and the reduction of nutrient losses).
