た。On the other hand, a number of methods of using a water-insoluble highly water-absorbent resin as a soil water retention agent for agriculture and horticulture have been proposed. Super absorbent polymer is originally used for disposable diapers,
Since it is used for sanitary materials such as sanitary products, its particle size is generally about 0.1 to 1 mm. For this reason,
When this was used as a soil water retention agent, there were problems such as scattering by wind and difficulty in uniform mixing when mixing wet soil.
