EXTENDED-RELEASE COMBINED FERTILIZER AND HUMIC GRANULES
20230121165 · 2023-04-20 · ·

A granule defined by a shape and a size, including a mass formed of a plurality of soluble fertilizer particles and a plurality of humic particles and an extended-release polymer coating surrounding an exterior surface of the mass. A process for forming the granule includes providing a mass of a plurality of soluble fertilizer particles and a plurality of humic particles and applying an extended-release coating to an exterior surface of the mass. The granule is used in a method for enhancing root growth of a target plant, such as turf grass, by applying a plurality of the granules to the target plant and allowing sufficient time for extended release of nutrients and humics from the plurality of granules.

PROCESS FOR TREATMENT OF SEWAGE SLUDGE AND PRODUCT OF SAME
20230159403 · 2023-05-25 ·

A process of treating sewage sludge and the formation of a granular product thereof, wherein said process comprises utilizing a urea-formaldehyde resin to treat a sludge product from thermal hydrolysis processes (THPs) to create an end product for agricultural and other uses. The process utilizes a high intensity mixing and chopping reactor, which combines the sludge with a resin and utilizes sulfuric or other mineral acid to polymerize the resin. The resultant product is subsequently dried and sized through a screening process. The process results in an end product that is a granular fertilizer that is substantially dehydrated and a substantial portion of the nutrients having low solubility and slow release rates. This reduces or eliminates the loss of plant nutrients to water runoff effects. The novel process results in a product that is a low-odor, enhanced fertilizer useful for the processing and utilization of sewage sludge for agricultural and other purposes.
