Method for producing high-grade fertilizer

Abstract

A method for producing a fertilizer and decay promoting substance by subjecting grape marc to aerobic decay so that in a first phase, the sugar content is converted to alcohol and bacterial fermentation produces organic acids. During the first phase, the alcohol and acids react to produce aromatic esters and a decay stabilized mass. In a second phase, the mass is rearranged to facilitate access of air and promote penetration of the mycelia of a thermophilic actinomycete into the mass. In a third step, the mass is rearranged to effect microbial degradation by the actinomycete mycelia and the mass is dried and the pip-containing fraction is separated. The thus obtained pips or seeds are infested with mycelia and still contain their natural oil content and constitute an excellent high-grade fertilizer and aerobic decay promoting agent for the decay of vegetable and animal waste materials.
