The Need

The greenhouse industry is increasingly concerned with the environmental impact and economic volatility associated with the use of synthetic fertilizers in soilless substrates. With growing awareness of water contamination risks and fluctuating fertilizer prices, there is a pressing demand for alternative tools that enhance phosphorus (P) management. Sustainable solutions that improve fertilizer use efficiency while maintaining or enhancing plant growth are essential for the industry’s future.

The Technology

This innovative technology involves the use of Plant Growth Promoting Rhizobacteria (PGPR) strains that significantly enhance the efficiency of phosphate use in greenhouse-grown ornamental plants. Thirty-two bacterial strains were identified, which effectively solubilize calcium phosphate in vitro, improving the availability of this essential nutrient to plants. These strains were isolated from a novel greenhouse rhizobacteria collection, with several demonstrating the ability to promote plant growth and health in marigolds. The technology offers a natural, effective solution for optimizing phosphorus management in greenhouse systems.
