Short Description of the Technology

Technology for optimization of composting of agricultural waste is based on newly developed, innovative microbiological consortia. Selected strains of microorganisms have properties of accelerating the degradation process of organic matter during composting. Consortium of beneficial microorganisms for biodegradation of organic matter, containing the following strains was developed: Priestia sp., Bacillus spp., Streptomyces sp. Newly developed consortia contain selected and never before used strains of microorganisms. The strains of beneficial microorganisms isolated from the soil around plant roots and from the rhizosphere soil of horticultural and agricultural plants were inoculated on specific agar-based growth media. Cultures were tested on presence of potential mechanisms responsible for stimulation of vegetative growth of plants (phosphate solubilization, siderophore production, nitrogen fixation, production of indole acetic acid).

Type of Contribution (e.g., reduction of nutrient losses, greenhouse gas emissions, etc.)

The selected strains of beneficial microorganisms have the ability to accelerate the degradation process of organic matter during composting and increase the retention of N and P and other macro- and microelements by plants. This can reduce the losses of these elements from the soil to surface waters and groundwater and to the atmosphere.

Benefits for farmers, the industry, and the environment

The development of consortia of beneficial microorganisms is compatible with solutions found in the natural environment, and at the same time is profitable for agricultural producers and companies producing biofertilizers. Microbial consortia increase soil microbial diversity and provide environmental, social and economic benefits. Newly developed microbiological consortia enable sustainable use and management of agricultural areas, have a positive impact on soil biodiversity and the health of society.
