Humus prepn. from vegetable waste - using enzymatic reagent contg. giobertite non diastatic malt extract, salt, yeast wheat flour and wheat germ

摘要

Humus is prepd., pref. from vegetable waste, by activating an enzymatic reagent subjected to a fermentation phase in a suitable reactor, reacting with a mixt. of water, calcium superphosphate, ammonium nitrate and potassium sulphate, and spraying the prod. over vegetable residues. The enzymatic reagent consists of non-diastatic malt extract, magnesium chloride, common salt, bakers' yeast, giobertite, wheat flour and wheat germ. Fermentation is for 50-80 hrs. at 38 deg.C, and subsequent reaction with the above mixt. is at 45-50 deg.C. The humus is obtd. 3-5 weeks after spraying.
