Nitrozyme is a plant extract derived from sea weed. How does Nitrozyme work ? When a plant is under stress at any given stage of growth reduced levels of cytokinin growth hormones are produced. If this reduction occurs at certain key stages of growth such as the vegetative stage yields can be affected. By making Nitrozyme available to the plant at these stages you can influence the crops final yield. Nitrozyme has been proven to effectively relieve stress and provide a more vigorous and healthy plant which increases yields and profits.
