| titleOfInvention | Controlled release fertilizer gel composition and process for its production |
| abstract | Methylene diurea, either alone or as a component of methylene urea polymers acts as a gelling agent for producing a gel composition capable of suspending particles which are insoluble in a liquid medium. Methylene diurea as the gelling agent in a liquid medium can be used to obtain novel gel compositions in the absence of added thickener-suspending agents. The methylene diurea is present in an amount greater than the solubility limit of methylene diurea in the liquid medium and in an amount sufficient to provide a gel for suspending insoluble particles. The process for producing the gel composition includes subjecting a dry methylene urea composition in particulate form to a shearing action in a liquid medium wherein the methylene urea includes an amount of methylene diurea greater than the solubility limit of methylene diurea in the liquid medium. Controlled release nitrogen fertilizer compositions are obtained which exhibit agronomic advantages over conventional fluid nitrogen fertilizers and offer material handling and application advantages over dry forms of fertilizers. |
