Description: Bioorganic Fertilizer The present invention relates to the field of biotechnology, namely, to agricultural waste processing, in particular, to the processing of manure and poultry dung, and can be used for the rehabilitation of oil- and oil product-polluted soils, fertilizing of humus-depleted soils, and crop increasing. Manure, especially rotten, i.e., bacteria-affected one, has been the basic agricultural fertilizer since the ancient times. However, a drawback of natural bacterial manure processing is the significant process duration caused by the absence of mineral fertilizers and the small volume of initial bacterial cultures involved in manure processing. A notable number of artificial bioorganic fertilizers have been developed over the recent time. There is the bioorganic fertilizer according to EP 0445102 C 05 F 3/00 Application of 1991, which is a preliminarily fermented mixture of liquid and solid animal excrements and organic materials, mixed with greenery and composted. A drawback of this bioorganic fertilizer is its low efficiency for the rehabilitation of oil- and oil product-polluted soils and complex preparation procedure. There is a fertilizer made of composted vegetable waste mixed with cattle rumination products (SU Inventor's Certificate 1578117 C 05 F 11/00, 1990). A disadvantage of this fertilizer is the low biological nutrition value and the low efficiency for the rehabilitation of oil- and oil product-polluted soils. The closest counterpart of the present invention is the bioorganic fertilizer according to SU Inventor's Certificate 294825 C 05 F 3/00, 1971, i.e. manure processed by methane bacterial cultures. A drawback of this invention is the low efficiency for the rehabilitation of oil- and oil product-polluted soils. The technical problem solved by the present invention is the development of an ecologically safe bioorganic fertilizer convenient for oil- and oil product-polluted soil rehabilitation and amelioration of humus-depleted soils. The practical result of the present invention is a considerable improvement of the ecological situation due to soil purification from oil and oil products with further involvement of the purified soils into the agricultural turnover. The said result is achieved by exposing manure and poultry dung to microbiological fermentation and adding an active nonpathogenic oil-destructing strain or strain association in an amount of less than 0.2 wt.%. This microorganism strains or association are yeast and/or bacterial non-pathogenic culture of Endomycopsis fibuligera, Pseudomonas species, Corynebacterium species, Pseudomonas pseudoalkaligenes, Methanobacterium species, or the like. The oil-destructing strains can be introduced into the fertilizer during or after microbiological . fermentation. The bioorganic fertilizer may contain nitrogen, potassium, phosphorus, and micro- or macroelement sources in amounts necessary for vegetation. Microbiological fermentation can be applied to fresh or rotten manure, which can be mixed with other organic wastes before the processing. Microbiological fermentation is performed in a conventional manner by introducing a fertile substance containing nitrogen, potassium, phosphorus, and micro- or macroelement sources necessary for the vital activity of manure processing microorganisms. If necessary, additional amounts of nitrogen, potassium, phosphorus, and micro- or macroelement sources can be mixed with the fertilized manure at this stage in order to auspice the development of oil- processing microorganisms in the rehabilitated soil. Depending on the introduction conditions, the bioorganic fertilizer may contain aerobic and/or anaerobic microorganisms, and the contents of macro- and microelements and nutrients are determined by the soil condition. To produce the bioorganic fertilizer, manure and poultry dung are loaded into a fermenter of any design together with a necessary amount of nutrients and, if necessary, water. After that, a manure fermenting microorganism culture is added, appropriate process conditions are produced, and the manure fermentation process is initiated. If the fermentation is performed at oil- or oil product-polluted sites, then the manure to be processed is compounded with oil and oil product biodegrading microorganisms in an amount of 0.2 wt.% and, if necessary, appropriate fertilizing elements, such as potassium and ammonia salts of phosphorus acids or complete ammonium phosphate fertilizers in amounts required for microorganism strain development and soil rehabilitation. The development of oil pollution biodegrading microorganisms can be accelerated by microorganism growth activators, for example, by ammonia salts of arylacetic acid in amounts of 10 "6 % to 10 "4 % by weight. The thus prepared bioorganic fertilizer is introduced into the polluted soil using conventional methods. If the fermentation is performed at cattle or poultry farms, the fermented manure or dung is transported to the soil rehabilitation site, where it is additionally blended with mineral substances, growth activators, and a culture of oil and oil product biodegrading bacteria in the same amounts, and then spread in the polluted soil using a conventional method. Invention application example. Liquid native poultry dung is loaded into a circulation-agitated airlifting fermenter, compounded with potassium phosphate in an amount of 1% of the dung weight, microelements, i.e. copper, iron, zinc, and molybdenum salts in a total amount of 0.1% of the dung weight, a suspension of active cultures of Endomycopsis flibuligera Y-2173, Pseudomonas species B-6782, and Pseudomonas pseudoalkaligenes Y-6783 in a total amount of 0.15% of the dung weight, and a microorganism growth activator, i.e. an ammonia salt of arylacetic acid in a concentration of 10 "5 wt.%. After that the mixture is fermented for 70 hours. The thus prepared bioorganic fertilizer is then spread uniformly over an oil product- polluted soil area, and the soil is plowed in. The claimed bioorganic fertilizer has allowed 72% of the test oil-polluted soil area formerly inapplicable for cultivation to be involved into the agricultural turnover. The introduction of this bioorganic fertilizer has made possible rye cultivating with a mean crop of 4.5% greater than for the reference soil area. The above examples do not restrict the possible preparation methods and applications of the claimed fertilizer.
