ABSTRACT:
The present invention provides a soil conditioner composed of a powdery or granular composition in which a filler is integrally included in hydrogel and a method of producing the same wherein an aqueous solution of a hydrophilic cross-linkable polymer is mixed with a filler and then the mixture is subjected to cross linking treatment by which the polymer is made to have cross-linked structure and formed into gel. Since the filler is integrally included in hydrogel, the soil conditioner, when mixed with soil, does not separate into the respective components, and there is no problem of the hydrogel emerging up to the surface of soil with the passage of time.
