Abstract
A method for manufacturing pelletized fertilizer includes the following steps of: mixing a biodegradable material and a water-soluble polymer material to form a first mixture; mixing a polyol, water and a nutrient salt to form a second mixture; mixing the first mixture and the second mixture to form a conglomerating gathered third mixture, and stirring the conglomerating gathered third mixture to form small lumps of the third mixture; spraying probiotic endo spores on the small lumps of the third mixture to form a plurality of fertilizer blocks; heating the fertilizer blocks, and extruding the fertilizer blocks to form a fertilizer strip; and cutting the fertilizer strip to form a plurality of pelletized fertilizer.

A method for manufacturing pelletized fertilizer comprising the following steps of:
- mixing a biodegradable material and a water-soluble polymer material to form a first mixture, wherein the water-soluble polymer material is selected from a group consisting of carboxymethyl cellulose, xanthan gum, shellac, guar gum, natto gum, pectin and poly lactic-co-glycolic acid;
- mixing a polyol, water and a nutrient salt to form a second mixture;
- mixing the first mixture and the second mixture to form a conglomerating gathered third mixture, and stirring the conglomerating gathered third mixture to form small lumps of the third mixture;
- spraying probiotic endospores on the small lumps of the third mixture to form a plurality of fertilizer blocks;
- heating the fertilizer blocks, and extruding the fertilizer blocks to form a fertilizer strip;
- and
- cutting the fertilizer strip to form a plurality of pelletized fertilizers.
A pelletized fertilizer comprising:
- a biodegradable material including starch;
- a water-soluble polymer material selected from a group consisting of carboxymethyl cellulose, xanthan gum, shellac, guar gum, natto gum, pectin and poly lactic-co-glycolic acid;
- a polyol;
- a nutrient salt;
- and
- probiotic endospores;
- wherein the biodegradable material, the water-soluble polymer material, the polyol, the nutrient salt and the probiotic endospores are mixed to one another.
