Abstract

The invention relates to agriculture and environmental protection from contamination of groundwater with products of intensive chemicalization of agriculture and organic decomposition products with humus. The purpose of the invention is to accelerate the enrichment of the root layer with organic nutrients and moisture due to the creation of a layer with enhanced sorbent properties. to humus. The surface of the sandy soil is leveled and a layer of 35-40 cm is removed. A water-retaining layer is placed under the root layer, containing wt.%: Peat 45.00-50.00; Sug on 40.00-43.00; lime 1.00-1.50; ilmenite 0,25-0,35; United States 0.01-0.02; liquid nitrogen - the rest; a bout 2-6 cm thick is covered with a previously removed layer of soil. After laying the layer in the first 2-3 years, alkaloid lupine is grown. 2 tab. F CO

Description

ND

The invention relates to agriculture and the protection of the environment from the pollution of groundwater by the products of intensive chemicalization of agriculture and the decomposition products of organic substances — humus.

The purpose of the invention is to accelerate the enrichment of the root layer with organic nutrients and moisture due to the creation of a layer with increased sorbing properties to humusuo. ,

Example 1o As the components of the interlayers, well-decomposed peat, loam with a particle content of up to 0.001 mm of at least 15-20% is used. Lime (lime flour) GOST 14050-78, silicone-silicone liquids of the GKZh-10 or GKZh-11 brand according to TU 6-02-696-76.

Ilmenite is a waste of mining and processing plants of the following composition,%:

Liquid cattle manure contains 86.6 + 3.5% organic matter 10%; total nitrogen. About 37 ammonia nitrogen 0.09%; phosphorus 0.1–7% potassium 0.23% (based on the substance). Organic matter in the dry mass of manure 70-80% o

In any capacity, for example in. dug trench by thoroughly mixing the constituent components with hydraulic pumps, May.%. peat 48; loam 42; lime 1,3; ilmenite 0.3; silicone (GKV-10) 0,015; slurry up to 100%, prepare a homogeneous suspension.

Level the surface of the sandy soil and remove a layer of 35-40 cm

On the prepared surface, the suspension is hydraulically fed up to the formation of an interlayer with a thickness of 3 (possibly 2-6) cm, which is attached to the previously removed soil layer.

In the year of sowing of alkaloid lupine, up to 1 centner of phosphoric and potassium are added.

fertilizers and 2-3 g grow lupine,

PRI me R 2, In a field of 1 ha of sandy or sandy sod-podzodo, a sheet of soil is plowed to a depth of 35-40 cm. The plowed surface is rolled by rollers, with the help of manure spreaders a uniform layer of peat is introduced - 144 t ha, then sugar - nok - 126 t / ha. Subsequently, the organic loam layer using an PETP-9654 machine is poured with liquid manure of 25.14 t / ha and lime fertilizer (RUM) of 3.9. T / ha and ilmenite 0.9 t / ha with subsequent harrowing and by spraying a suspension of silicone with a tractor sprayer at the rate of 0.06 t / ha of active substance (silicone). The organo-mineral mixture treated in this way is rolled and, using a plunger, the coulter is laid at a depth of 35-40 cm, phosphorus and potassium fertilizers are applied during sowing, and the alpine lupine is grown for 2-3 years. h

The effect of the qualitative and quantitative composition of the layer on, its sorption and filtration properties are presented in the table

The effectiveness of the proposed method in terms of accumulated humus in the root layer of sandy soils in comparison with the control is given in Table 2 „1.

Using the proposed method allows for 2-3 g to accumulate 30.5.t / ha of humus (respectively, 1.52 tons: Ira. Of nitrogen), contributes to its gradual and even return to plants and serves as a potential reserve for obtaining high yields of agricultural crops.
