Hydrogel sap, agricultural superabsorbent hydrogel for agriculture

Water retention agent(WRA) is a new kind of product which is very useful in agriculture. We produce this product in our own factory so that we can control the quality strictly. Our product is good sold in the north of China, South America, and some areas of Europe.
◊Water retention and Drought control. When the WRA absorb enough water, even if it doesn't rain for a month and there is no watering ,the crop can also grow normally.
◊ Protect fertilizer efficiency. The WRA can store the fertilizer that is melt in water, and then supply the fertilizer to the crop root slowly. This can reduce the wastage and increase the efficiency.
◊ Soil improvement.WRA is a kind of organic compound. It turns to be gelatinous after absorbing water, which is very easy to make the soil granule and make the soil more loosen.
◊ Promote crop growth, raise emergence rate and the survival rate. Using WRA can increase seedlings transplant survival rate 10-30%, mature trees transplant survival rate above 50%, and it also can reduce the slow growth time observably.

Solid water resin is composed of low molecular substances by polymerization of synthetic polymer. Because of the molecular structure crosslinking, the water absorption of molecular networks can not be squeezed out by general physical methods, so it has a strong water retention property. It can rapidly absorb deionized water hundreds of times heavier than the salt water containing dozens of times to nearly a hundred times, and has the function of repeated water absorption, water after the expansion of hydrogel, then slowly release water for seed germination and crop growth and utilization, so as to enhance the performance of soil moisture, improve soil structure, reduce water leakage in deep and soil nutrient loss, increase water use efficiency. Water retention resins are suitable for use in areas where precipitation is scarce, rainfall is uneven in the annual season, and in areas lacking irrigation water.
