water absorbent polymer ----water retaining agent

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.
Water Retaining Agent is acrylate/acrylamide 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. 

2. Function and characteristics
    (1) It has super water absorbing capacity. It can absorb and retain rain and irrigated water quickly, and release water slowly when the plant needed. Thus it can guarantee the water that the plant needs for growth, prevent the waste of water caused by evaporation, seeping, and running off, keep the soil moist for a long time, and absorb and release repeatedly for the plant. The experiment proves that the water retained in soil that use Water Retaining Agent is 5-15% more than that does not use it, and it can economize 50% upwards of water.
    (2) Improve the soil's structure. (Granule structure, water permeability, ventilation, thermal capacity) Iterative contraction and expansion make lots of holes and space in soil, increase ventilation and water permeability of soil, and improve the environment around the root, and boost up the activity of microorganism around the root, quicken the decomposition of organic mineral that advantageous to root system's absorbency, accelerate the plant's growing, improve the soil's foundation and prevent the soil become hardened and Stalinized.
    (3) It can keep its stability and efficiency in all kinds of soil, for various plants, and under different conditions of weather.
    (4) It can accelerate the plant's growing, and increase the seed's germinating rate by 5-15%, accelerate the root system's growing, and make it grow deeper and thicker.
    (5) It can economize agrochemical and fertilizer. If mix the agrochemical and fertilizer with it, it can also retain the agrochemical and fertilizer while it store the rain and irrigation water, and release afterwards. Thus the agrochemical and fertilizer will not be waste because of evaporate, seeping and running off, and increase the utilization of the agrochemical and fertilizer.
    (6) It has passed the test of environment inspection organization and the hygiene epidemic department. It is non-poisonous, harmless and has no side effect. It makes no pollution to the environment in its using period.
    (7) The product application is wide, and it can be used repeatedly, and the period of validity can be 2~3 years.
