URB Natural is an 100% eco-friendly, broad spectrum, stimulative, poly-microbial agent. The microbes might have been made by natural, but they are then cultivated by URB Sciences. Inside each bottle are six strains bacterial microbes including Trichoderma Harzianum, suspended in an 12% humate liquid, allowing for maximum absorption potential. The humate derivatives are mixtures of humic, ulmic and fulvic acids. They are products of organic matter transformation by the soil microorganisms. Additionally, humic acid derivatives have several known benefits, such as increasing rapid seed germination, improving trace element nutrition through chelation, and improving moisture conditions.
