[Optimization of vermicomposting of organics enriched with phosphorites with participation of phosphate-mobilizing microorganisms].

Active strains of microorganisms capable to mobilize phosphorus from poorly soluble compounds were isolated from the vermicompost. Representatives of Pseudomonas genus dominate in assemblages of phosphate-mobilizing humus microbiota. The strains Pseudomonas sp. 17 and Pseudomonas sp. 22, which promote liberation of the greatest quantity of water-soluble phosphorus were selected under vermicomposting of organics enriched with phosphorites with participation of active phosphate-mobilizing microorganisms. The use of compost derived with participation of Pseudomonas sp. 17 in cucumbers growth technologies makes the plants development better and raises the cultures productivity.
