SOCO® Superabsorbent Polymers have passed several kinds of strict internatioal certificates test, like SGS, ISO, Reach,BV.

Ultimate FAQs about Superabsorbent polymers:

Agro Sap / Solid Rain is Potassium polyacrylates Powder or granule, turns to be Hydrogel Polymers when meets water / absorbs moisture;

It has the ability of holding & control-release of water and things in water;

It has many names: hydrogel, water retention agent, solid water, solid rain, agro sap powder, agro slush powder, water gel, water-retaining gel, water retention agent, water retaining hydrogel, etc.

As a default, Agro SAP/Solid Rain is a kind of Powder or Granule, easy for transport or storage;

When absorbs water or moisture, it becomes a kind of hydrogel, the weight or size is expanded much.

Plant roots can get moisture or nutrient from this hydrogel.

Potassium polyacrylate polymer can be used for many purposes.

We mainly used it as Agro SAP holding water for plants, improving soil conditions, and protect environment.

As said above, they are all super absorbent polymer and have the ability of water-absorbent;

But different from Sodium polyacrylate, Potassium polymer will not cause soil salinization, so we take it as a water retention agent for agriculture plants.

Plants like Potassium more.

Potassium polymer is biodegradable and there is no bioaccumulation;

Usually, we say SAP is no toxic, safe, and no danger under the right guide & dose. But in some condition, it brings irritation, so:

Don't sawllow it, don't contact with your eyes, nose, mouth, etc.

SOCO is Professional supplier of Super Absorbent Polymer SAP Powder;

We mainly offer agro SAP powder / Granule of potassium polyacrylate, we also make sodium polyacrylate at high grade & best price.

Uses of SAP Super Absorbent Polymers for Agriculture

Saving Water & Fertilizer, Get Harvest

Harvest with Less Fertilizer.

Survival Rate Improved

Balanced & Better Growth

for Germination Rate, Rapid Sprouting

Water Holding Improves Plant Growth

Less Water Loss, Improve survival rate.

Absorb Waste/Odor, Keep Good Condition.

Resistance to Heat Shock & No Leak

Powder water crystals for plants in large-scale farming

Powder water crystals for plants has also shown its effectiveness in large scale farming. The storage of rainwater or irrigation water by SAP delays the wilting point and thus makes it possible for certain plants to begin to be well established while waiting for the water regime to become adequate.

For example, in the farming of rain-fed sugar cane, significant increases in yield of approx. 25% are observed.

  • When replanting a field, put polymer in the furrows where the cane shoots are placed.
  • Powder water Crystals may be applied at the same time as a fertilizer.
  • Cover the shoots with soil by earthing up.

Water retention agent special for lawns and sod

SOCO® polymer is very easily used throughout the growth cycle of lawns and sod. They ensure good germination, faster root development, and regular and even growth of lawns. The rooting of sod is also faster. They are widely used in landscaping for golf courses and grass in parks and gardens.

  • Work, break up and level the soil to be planted with grass.
  • Spread SAP polymer on the surface of the soil. The polymer may be broadcast or applied with a fertilizer spreader for more even distribution.
  • Work polymer into the soil to a maximum depth of 10 cm. This can be done by hand with a spade or mechanically with a disk plow or a rototiller.
  • Seed the lawn or lay the sod. Roll the soil to compact it.
  • Use fertilizers if needed.

Water retention agent special for mixing with fertilizers

To reduce leaching of nutrients in the soil, SOCO® Polymer may be mixed dry into fertilizer preparations. The behavior of plants fertilized with this mixture makes it possible to maintain or even increase yield while at the same time protecting the environment from leaching. Manufacturers' test results also show better root development of the plants.

  • Savings on the order of 15% to 30% are observed in the amount of fertilizers.
  • The polymer is added dry when the fertilizers are manufactured.

Water retention agent special for Arboriculture

SOCO® polymer is effective in the planting of trees, bushes, and jungle. It makes it possible to reduce the mortality rate during transplanting and to enhance root development and therefore brings about more rapid growth and production.

  • Dig a hole about three times the volume of the root system.
  • Mix 1 to 2 kg of SOCO® polymer per m³ into the earth fill.
  • The polymer must be evenly mixed into the excavated soil. A small amount of untreated soil must be set aside.
  • Place the root ball of the plant at the bottom of the hole and fill in the hole with the treated soil. Make sure that the product is distributed evenly around the roots. Then cover the surface with 5 cm of untreated soil to prevent degradation of the polymer by ultraviolet rays and stagnation of water on the surface.
  • Be especially careful not to put an unmixed dry product at the bottom of the hole. After hydration, the product would destabilize the plant.

Water retention agent special for horticulture

SOCO polymer for horticulture can be added to the soil when plants are planted, which will increase the survival rate of plants, increase the drought resistance of plants, facilitate plant generation, and reduce garden care costs.

Water retention agent special for Transplanting adult trees

The use of SOCO® soil water retention agent is one of the main technical guarantee measures for the "site formation" of large trees with canopy transplantation. 

Combined with early root cutting (limiting the root width and stimulating the formation of new root caps), proper pruning and leaf removal (reducing water consumption by transpiration), moisturizing the trunk, applying transpiration inhibitors and rooting agents, and controlling burial depth, etc. After the big trees are transplanted, the water balance is quickly restored, and the survival rate of transplanting in summer can reach 95

Water retention agent special for vegetables

Using eggplant, chiehwa, and ribbed loofah as materials, two types of water-retaining agents with different particle sizes were used to raise seedlings to study the effect of water-retaining agents on vegetable seedling quality and fertility retention. The results show that the higher the concentration of the water-retaining agent in the seedling substrate, the stronger the fertilizer-holding capacity of the seedling substrate, but when the concentration of the water-retaining agent is too high, it will inhibit the growth of vegetable seedlings, and the low-concentration water-retaining agent has a significant effect on promoting the growth of vegetable seedlings, and the small particles The seedling strengthening effect of diameter water retaining agent is better than that of large particle size water retaining agent. When the concentration of small particle size water retaining agent is 1%, the seedling effect is the best. The plant height, stem thickness and maximum leaf area of eggplant, chiehwa, and ribbed loofah seedlings Both reached the maximum value, and the difference was extremely significant compared with the control.

Water retention agent special for greening project

SAP polymer is commonly used in greening project:

  • stabilizes newly graded soils, maintain a minimum of surface water;
  • reduces the amount of mulch;
  • prevents cellulose mulch from becoming hardpan;
  • helps rapid sprouting of seedlings even in dry areas.

The vegetation cover develops uniformly and rapidly over the whole treated surface. There are no dry spots without grass.


  • SOCO® polymer must be added last to the hydroseeder tank, after the other components: seeds, fertilizers, mulch, etc.
  • Stir at least 15 minutes before spreading.

Brief User Guide of SOCO® SAP Polymer

Dry Application

1. Mix it with fertilizer and soil evenly and then apply the mixture to the ground by using fertilizer applicator.

2. For the confined area (less than 20 square meters), it is recommended to apply manually.

3. Completely turn over the ground by using tillage machine (require it at depth of 20cm).

4. Trampling the ground.

5. Watering the ground.

Wet Application

1. Let SAP absorb 200 times water, become gel;

2. Put into the sowing furrow;

3. For the confined area (less than 20 square meters), it is recommended to apply manually;

4. Put surface soil in order before plant;
