Water Retaining Agent is a kind of new functional water absorbent polymer, It contains lots of hydrophilic groups and excellent molecule structure. It can absorb hundred times of water of its own weight in a short time, and release afterwards slowly and absorb repeatedly. Therefore, it can form a miniature reservoir around the plant's root, keep a moist environment and develop water and fertilizer retaining capacity of soil effectively, increase using rate of water and fertilizer, improve the structure and ventilation of soil, create a good growing environment for the plant.
The Water Retaining Agent is potassium polyacrylate copolymer. It is produced by advanced equipment and unique techniques; Therefore the product's capacity becomes more excellent. The product's absorbing rate is high, and the gel is firm after absorbing water. It can be used repeatedly under the soil's pressure, and keep the soil ventilated and keep the soil from hardening. It has super capacity of absorption, and it can release afterwards, so it can reduce running off, exaltation the utilization of the fertilizer and agrochemical, and lower the pollution of the environment. This product can degradable completely. It can be gradually degraded into carbon dioxide, water and nitrogen etc. After being used in soil for 2-3 years, so it is beneficial and harmless to the soil, and it will improve the original ecosystem environment.
