An organic-based uniprill fertilizer is provided. To produce the fertilizer, organic matter is sequentially pre-treated by first mixing it in a first grinder with a lime admixture, then adding a slurry of reagents and binders, followed by a mixture of acids. The acids can include sulfuric and phosphoric acids, in addition to nitric acid and various organic acids such as citric and fulvic acid, depending on the end requirements of the fertilizer product. Following the mixing of the pre-product with the mixture of acids and reagents, the resultant raw product is preferably processed through a second grinder. This grinding further dries, mixes and granulates the raw product. The particle size of the completed fertilizer is reduced into a flowable, user safe uniprill product that can be further ground to reduce its moisture. Further drying may be necessary for bag or bulk product, or it can be liquified by high speed blending or micro-fluidized for sprinkler or drip applications. The uniprill fertilizer comprises small, preferably microscopic particles that are homogenous in nature, in that any single particle is substantially identical in composition to all other particles of the fertilizer. Additionally, each uniprill particle contains substantially all sixteen nutriments and minerals required for the growth of healthy plants.
