Abstract
This invention describes discovery and development of a biological system of plant growth promotion and environmental improvement by carbon sequestration and/or nitrogen utilization by application of a microbial agent, e.g., a highly effective strain of T. viride, particularly strains NRRL B-50520 and/or K5. This strain outperforms the best current strains of Trichoderma used for this purpose available commercially. The highly active products also are expected to increase plant productivity and improve quality of fruits, vegetables, flowers or other plant products. The invention also describes and demonstrates that strain combinations including Bacillus amyloliquifaciens AS2 or AS3, as well as disclosed metabolites, promote plant growth. This is true across monocots and dicots, seed treatments and foliar sprays. In the field plant height, shoot weight, root weight, and photosynthesis (Spad meter readings) were all increased in comparison to the untreated control as well as the leading biological seed treatments. The invention also describes metabolite utilization for enhancing plant growth.
