| 摘要 |
The invention is a soluble, liquid or dry fertilizer for application to a plant or soil that is grown or farmed as "organic" as defined under the USDA National Organic Program Rule. The fertilizer is produced from distiller's yeast from beer and/or alcohol production. The yeast cells are autolyzed using heat and the autolysates are separated by centrifugation into insoluble cell walls and cellular plasma. The plasma is concentrated by evaporation into the fertilizer. The fertilizer may be further processed by proteolytic enzyme (protease) hydrolysis to produce smaller-sized, soluble, Nitrogen-containing compounds including protein, peptides, amino acids, amines and ammonia. The fertilizer has a solids content between ten and sixty-five percent, a total protein content of at least ten percent and up to eighty-five percent, a total Nitrogen content between one and fourteen percent, and a pH between 2.5 and 10.
