Superabsorbent, as the high molecular synthetic product, which can absorb water of hundreds of times of its weight in a short time and form granule formations in the soil to enhance its ventilating ability. Moreover, the?superabsorbent?as the water-insoluble polymer does not pollute the soil or natural resources because of its characters of super polymerization, non-toxic, non-irritating and non-corrosive. When adding SINOFLOC products to soil, it can swell and retain water near the crops root areas, and release the water readily as the soil drying, which makes them perfect?superabsorbent polymers in agriculture.
