Title: CONTROLLED-RELEASE FERTILISER AND METHOD FOR MANUFACTURING SAME
Abstract:
The present invention relates to a controlled-release hydrogel and the method for manufacturing same. Specifically, to a controlled-release hydrogel comprising a cross-linker, cellulose, a hydrogel-forming polymer and an active composition, whereby the composition may be nutritional or biocidal. The method for manufacturing same comprises (a) mixing a polymer in water with cellulose, (b) mixing a cross-linking solution and a composition, and finally mixing the solution from step (b) with the mixture from step (a), stirring constantly until a hydrogel is formed. Shaping and drying the hydrogel obtained.
