The invention relates to ecology and agriculture, namely to fertilizers containing molybdenum, and is intended to increase productivity and nitrogen fixing ability of legumes peas on the basis of the disposed waste industry.

A method is known in which use industrial waste, mixed with mineral substances (patent No. 2411223 from 10.02.2011, IPC C05D 5/00).

Known fertilizer is unprofitable, as for use of recycled magnesium-containing wastes must be dissolved in sulfuric acid at a temperature of 40°C and thoroughly stirring the product of the decomposition of nitric and phosphoric fertilizers.

It is also known technical solution, in which the use of additional chemical macro - and trace minerals, containing potassium, magnesium, sulfur, phosphorus, nitrogen and other substances (patent No. 2258053 from 10.08.2005., IPC C05F 3/00).

However, this solution is rather complicated to prepare such a composition, including bird droppings and natural zeolite.

Also known method of preparation of fertilizers containing peat, mineral nutrients, trace elements (patent No. 2490241 from 20.08.2013, IPC C05F 11/02; C05D 9/02).

However, the method is complicated by the fact that nitrogen-ammonia component is further treated with ultraviolet rays.

The closest technical�m solution is a method, where it is used as a substrate waste industry for the cultivation of leguminous plants, particularly peas, soybeans, clover, consisting of molybdenum, copper, iron, sulfur (patent No. 2461184, from 20.09.2012 G., IPC A01G 31/00, bull. No. 26).

However, in the method used as a prototype, applied clay deposits, mixing them with the waste industry, which is insufficient for the growth and development of plants legumes. In the known technical solution is increased germination and energy of germination, and in the phase of branching growth is slowing due to the lack of organic matter and other minerals.

The technical result - improvement of agrochemical properties of soil with simultaneous waste management industry.

The technical solution of the declared object is that for the preparation of a mixture of molybdenum-containing waste industry and organic matter in the form of dry poultry manure in the ratio 1:5 and make it on sod-podzolic soil before planting peas.

Study of the effect of molybdenum-containing waste (MOE) of the plant "victory" (Vladikavkaz) was performed in vegetative experience in the cultivation of peas in the phytotron of the all-Russian research Institute of Agrochemistry named after D. N. Pryanishnikov (Moscow) under the scheme:

1. Control without fertilizer.

2. Bird dung.

<> 3. Molybdenum-containing waste + poultry manure in the ratio 1:5.

Dose dry bird droppings per 1 ha was 5 tons, molybdenum-containing waste 1 T.

In the studied dose of molybdenum-containing waste industry has a positive effect on nitrogen-fixing ability of peas, contributing to the growth in the number of nodule bacteria and their masses, and, ultimately, increasing the biomass of aboveground and underground organs of crops and increasing the yield.

Example. Experienced the culture of the pea variety alpha, used on the green mass. The air temperature in the period of experience in the phytotron maintained at 24-25°C day and 20°C at night. Lighting was provided by fluorescent lamps. Illumination 12 Klux, photoperiod 14 hours. In accordance with the scheme of experience in vessels placed soil, thoroughly mixed with organic fertilizers (dry poultry manure) and molybdenum-containing waste.

Planting peas performed to a depth of 3-4 cm Shoots appeared on the 4th day after sowing. The soil moisture in the vessels was maintained at a level of 75-80% of field capacity.

After accounting for harvest of the crop was dried to determine the content of major nutrients - total nitrogen, phosphorus, potassium, heavy metals.

The soil of experience sod-podzolic heavy loam, characterized by the trail of�forming agrochemical characteristics: pH of 5.4, the humus content of 2.7%, available phosphorus (P2O5) Kirsanova 575 mg/kg, potassium (K2O) 151 mg/kg.

Manure contains 75% organic matter, 2.1% of the total nitrogen, 0.1% of ammonium nitrogen, 3.7% of phosphorus (P2O5), The 2.0% potassium (K2O) at pH 7.6.

As a result of the research showed a positive significant influence on the biomass of pea plants molybdenum-containing waste in combination with bird droppings. In a joint application of waste containing molybdenum, and bird droppings aboveground biomass grown during the month of pea plants per 1 m2was 900 g, which was higher than the control at 212 g (31%) with least significant difference (HCP05) 192 G. Thus, from the combination of molybdenum-containing waste and litter was obtained significant yield increase vegetative mass of peas. At the same time from making the same litter biomass yield of peas amounted to 720 g/m2and increase relative to the control 32 m2(5%), i.e., was not significant.

Root weight of pea plants also developed better than in the variant with the use of molybdenum-containing waste and poultry manure, where there was significant growth in the roots. The number of nodules was 136 pieces on the vessel, which corresponded to the control.

The use of molybdenum-containing waste with bird droppings p�made it possible to obtain vegetative mass of peas favourable chemical composition and to improve agrochemical properties of the soil, especially the content of mobile compounds of phosphorus and potassium (table.1, 2).

The content of heavy metals: lead (1.6 mg/kg), copper (28 mg/kg), zinc (8,8 mg/kg), cadmium (0,28 mg/kg) vegetative mass of the peas represented the maximum permissible levels for feed, and therefore it is quite suitable for use as green manure crops to improve the fertility of sod-podzolic soil.

Consequently, the use of molybdenum-containing waste plant "victory" in the mixture with bird droppings in the ratio of 1:5 on sod-podzolic soil is an important agro-ecological technique that allows to increase the yield of green mass of peas in average by 30% with simultaneous waste management industry, while maintaining the ecological safety of adjacent territories.

A method of using molybdenum-containing industrial wastes for the cultivation of peas on sod-podzolic soil, including soil molybdenum-containing waste, characterized in that a mixture of molybdenum-containing waste and dry poultry manure in the ratio 1:5, which is applied to the soil before planting peas.
