Abstract
A new fertilizer comprising of amino lignin compounds, which are made by delignification of biomass containing lignin utilizing amino compounds and producing amino lignin, amino lignincellulose and cellulose. The urea lignincellulose is reacted with potassium hydroxide to produce potassium salt of amino lignin and lignincelluose. The amino lignin is reacted with phosphorous acid to produce an amino lignin phosphorous acid. These amino lignin compounds reacted with potassium and phosphorous acid are the source nitrogen, potassium and phosphorus in the new solid or aqueous fertilizer.
