Abstract
A fertilizer composition and method to produced based on milk which comes from ruminant animals like cows and goats and adding a coal dust component. The previous or past milk-based fertilizers have had poor efficacy obtained due to the high fat content of these milk sources due to using too much milk, or rather too much fat in the milk, since the bacteria in the composition will spoil and result in a foul odor, poor growth, and poor crop yield. This fertilizer composition contains a nutrient ingredient, which is the de-fatted milk, as a liquid or dry product, and are utilized between 10 percent weight and 95 percent weight plus uses the coal dust and soluble coal dust as a less expensive stabilizer and chelator as well as other minerals for Nitrogen-Phosphorus-Potassium utilization.
