Agriculture Potassium Polyacrylate called super absorbent polymer is a new functional material with good water absorption and water holding capacity.We can use it absorbing, retaining or blocking liquid – Super absorbent polymer can absorb water up to hundreds times of its own weight and turn to water gel. As a Eco-friendly material, it is totally non-toxic, harmless and nonpolluting.
Agriculture grade super absorbent polymer consists of a set of polymeric chains that are parallel to each other and regularly linked to each other by cross-linking agents, thus forming a network.When water comes into contact with one of these chains, it is drawn into the molecule by osmosis. Water rapidly migrates into the interior of the polymer network where it is stored. That’s how super absorbent polymer powder turns to water gel.As this water gel’s absorption ability is bigger than soil but less than roots of plants, the absorbed water by super absorbent polymer will be released to plants when it is dry.
Tips: the specific retention of agriculture SAP is 1.3-1.4 MPa and the specific retention of roots is about 1.6-1.7 MPa
-improve seed germination & emergence, give plants an early, health start;
-contains Potassium 18.3% and release the fertilizer efficiency slowly;
-save the irrigation and improve the soil water holding capacity 85% (for sand);
– increase crops and fruit yield 70% (for melon planting in California).
