Abstract
A method of preparing high integrity natural nitrogenous granules for agriculture by heating natural nitrogenous materials under alkaline conditions until the materials develop adhesive properties, forming the materials into granules by mechanical means, and heating the natural nitrogenous granules until they harden; and the compositions formed by this method. The granules for agriculture include natural fertilizers, secondary nutrients, micronutrients, and natural animal feed protein supplements. The method also provides natural based plant food and animal feed supplement granules containing natural or synthetic additive substances which are useful in agriculture. The natural materials used in the method include poultry waste, poultry feather meal, hair meal, seafood meal, blood meal, bone meal, soybean meal, food waste, and grain by-products. The method provides natural nitrogenous granules which are free of disagreeable odor by admixing reactive aldehyde compounds with the natural nitrogenous materials prior to granule formation.
