Description

one

The invention relates to the production of organic fertilizers using microflora and allows the use of waste production of phosphate fertilizers.

The purpose of the invention is to improve the quality of the biologically active soil and reduce the complexity of the method of its production.

Example 1. A ground culture of AMB in the amount of 2 kg per 1 ton of harvested soil is added to the crushed butar product and, after mixing, is applied to the peat area with subsequent embedding (to a depth of no more than 10 cm). Peat on the mass is removed from the production area, placed in caravans and composted in the autumn-winter period using self-heating until February - March (the beginning of the greenhouses operation) at a humidity of 60-70%.

A bitumen product is a host rock of phosphorous deposits — mechanical waste from the production of phosphate fertilizers. Its chemical composition, in particular the combination of large amounts of CaO and P in it, provides both phosphorus nutrition and, unlike earlier use of lice phosphate flour, sour lice and without that sour peat, the creation of optimum quality for the development of AMB culture, and promotes better growth and development of plants in closed ground.

The relatively large (7–9%) content of the MgO butar product also plays an important role in the lime process, which provides a more gradual alkalization of the soil produced.

In addition, unlike other mineral fertilizers, a butar product contains very few easily soluble components that are usually extruded, so spreading it over the peat production area does not cause damage to the environment.

The amount of buty product introduced into peat (7-10%) is determined by the initial acidity of peat — with more acidic peat, it is equal to less acidic — 71. The final product should have constant indicators.

The proposed method was prepared by an experienced party biologically

active soil. A poorly decomposed peat with a pH of 2.5, and a total water-holding capacity of 35%, and a trash product of the following composition are used,%: P 0, 5 5.0; MgO 7.15; CaO 18.5; Re, 0 2.7%; AljOj 0.3; COj 16, insoluble precipitate D3.35, fluorine 2.0. After adding 10% of the product and the mother culture of the AMB and subsequent composting in the greenhouse for 2.5 May, the soil has the following characteristics:

Nitrifying ability with lupine flour (N-N0j) 300-400 mg / 100 g 20 The effectiveness of the soil prepared by the new technology was tested. The soil is used for growing cucumbers, tomatoes and seedlings.

When using soils for seedling and growing seedlings, experienced 6 varieties do not differ from the controls, and when growing plants, biologically active soil gives an increase of 12-13% compared to soils used in households.

Example 2. For soil preparation, an acid, slightly decomposed peat with a degree of decomposition of 10% is used. The peat has a pH of 2.5, the total moisture content of the peat is 35.0%.

In 1 ton of the indicated peat, 100 kg of a bucket product mixed with 2 kg of uterine culture of autox40 ton microflora B (AMB) are introduced.

The butar product taken into operation has the following composition, 5.0; MgO 7.15; CaO 18.5; Ge, 0d 2.7, A1 0 0.3 | F 2,0; WITH 16.0; insoluble

Used for the preparation of soil uterine culture AMB has the following characteristics: pH 7.0, the number of microorganisms in 1 g

50 is - the total number of bacteria is 6x10, the number of nitrifying bacteria is 1x10; the number of cell disintegrating aerobic microorganisms 6x10. The biological activity of the uterine culture by nitrate accumulation is 456 mg N0 / 100 g.

Soil preparation technology includes the following operations.

The milled peat is harvested, the manually prepared mixture of the bottom product with AMB culture is added to it, it is enriched and placed on composting in a greenhouse at. The mixture is subjected to composting for 2.5 months.

The resulting biologically active soil after composting is characterized by the following indicators; soil pH 6.8. Content, mg / 100 g:, 5; 350;

As the table shows, the soil prepared by the new method, in all respects, surpasses the soil prepared by the old method, both in physico-chemical and biological indicators, and in terms of plants grown on both soils.

Example 3. For soil preparation, use acidic, slightly decomposed peat with a decomposition rate of 18%. Peat has a pH of 3.6.

In 1 ton of the indicated peat, 70 kg of a bucket product mixed with 2 kg of UMB culture was added.

Butar and uterine culture of AMB have similar uses in Example 2 characteristics and composition. Soil preparation techniques are similar to example 2. Soil, obtained after composting for 2.5 months, has the following properties; soil pH 5.9; biological activity for nitrate accumulation of 342.4 mg g, total bacteria in 1 g of soil 1.1x10; the number of nitrifying bacteria in 1 g of soil 1x10.

As can be seen from the above data, the addition of a product in the amount of 7% ensures the production of a soil of quite satisfactory quality, better than the prototype.

In addition, the proposed method and and the message involves sieving all components on the surface of the peat, seal them and the extraction of milled peat.

In the old way all the necessary components; Lime, mineral fertilizers and AMB culture are introduced into the peat deposit separately, in 3 applications, since it is impossible to mix them. According to the new method, the introduction in 3 doses is replaced by a one-time application of a mixture of a bottled product with a uterine culture, which is possible due to the absence of toxic product in relation to AMB culture (lime and mineral fertilizers have one).

A reduction in labor intensity is achieved by reducing the number of operations in preparing the soil.
