It is a kind of polymer with super absorbent, water retention and water release abilities. It can absorb water up to several hundred times of its own weight, and creates a small reservoir which can rapidly absorb, store and slowly release water and nutrients. Meanwhile, this SAP retained water can rapidly absorbed by roots of all kinds of agriculture crops, trees, vegetables and flowers...etc. It can also greatly increse the drought- resistance of the plants.
