Super absorbent polymer (SAP) is functional polymer, it can absorb hundred times of its own weight of water in a short time, can absorb & release repeatedly. It’s non-toxic granules capable of absorbing and retaining many times their weight in water. SAP is a unique surface cross-linking chemistry which prevents gel-blocking and allows liquid to flow freely to the particles for efficient absorption.

In addition to providing excellent moisture control, they thicken fluids and turn them into a solid gel, swell when in contact with liquid, and exchange ions during absorption, it's know as mini water tanks (solid rain as well) in agriculture.
XITAO Aguasorb® absorbs liquid by utilizing osmotic pressure making it ideal for use in a variety of applications, such as agriculture,soil solidification,,ice packs and WWT.
It has been proven to be one of the most innovative, effective, and safe super absorbent polymers in the market today.

XITAO Aguasorb® is a registered Trademark in China, it is potassium based, contains K2O during polymerization,especially used in agriculture known as mini water tanks widely used in: 
-field crops
-vegetable & fruits
-gardening,tree planting,
-afforestation
-golf course,
-seeds coating
-desertification control etc.

XITAO Aguasorb® for agriculture use is potassium based, with 3 mesh size available:8-18, 18-80 & 200.

How XITAO Aguasorb® works for agriculture? 

When applied to the soil, each SAP granule absorbs over 400 times its weight in water, retains it and release that water "on demand",as needed by the plant. The SAP granules act like small sponges and are able to absorb and release water back to the root system,  over and over, during the course of 2 to 3 years.
A unique way to reduce moisture stress for greater yields and higher quality with increased payable.
For healthier early growth...

 ※ Keeps water in center of the hill, a challenging area in which to maintain moisture.
 ※  Increase soil moisture content, retention and supply to plant roots, where it's needed most.
 ※ Evens out moisture availability between irrigation cycles.
 ※ Reduces moisture stress, creating larger plant biomass.
 ※ Creates more rigorous root development.

Why choose potassium based SAP (KSAP)?

For agriculture use, potassium based SAP is strongly recommended, as sodium based might rotten the roots and cause soil cake. Potassium based SAP is the optimal type for plant growth, it’s good for root, stems & leaves.
How to identify SAP is potassium based or sodium based?

I. Identify product type
For agriculture use, please pay much attention to those sodium based SAP for disposal use, which is sodium polyacrylate product and degrade very fastly,as per the chemicals structure.

II. Identify the quality

Although both are co-polymers, but it exists potassium and sodium based types, sodium based is much cheaper than potassium based and it can rotten the plant roots and caused soil cake. Potassium based is for agriculture use only, it’s good for plant growth. Also, the cross-linking agent is different during polymerization, the less cross-linked typed with high absorbency rate, but with worse release performance and weak gel strength. Also the raw material purity ,crosslinker ratio, polymerization technology are essential to the product quality.

III. Identify the supplier

Fully check manufacturer’s production technology, raw material purity, solid content etc, ask samples to do the compared testing.

IV. Do grass seeds germination test
To check SAP product is potassium based or not, the simple way is to do the grass seeds germination test, steps as belows:
1) measure 1g SAP sample, put it into 110g tap water within 10minutes it will be hydrated to water gel.
2) measure 1g grass seeds, put them on the surface of the water gel.

3) after 4-7 days, the seeds put on the potassium based SAP gel will be germinated.

do the same with the compared sample.

Sodium based sample ( P1) degrades faster, and no seeds germinated, seeds get rotten.

you can see the difference of sodium based sample VS XITAO potassium based sample (P2), regarding sodium sample, there is no seeds germinated, XITAO samples have good germination rate.

It's the way that XITAO lab to check if SAP is potassium based or not, FYI.
ATTN: SAP shall be applied in the soil, can’t be used as soilless cultivation.

Application method
I. Dry method: mix SAP with fine soil, throw even into the planting furrow or planting cave, after sowing or planting, watering thoroughly, then covered with soil.
II. Wet method:make SAP to 120-130 times hydrogel. (i.e, mix 1G SAP with 120-130 ml water), then apply into the planting trench, mix even with ditch soil,then sow the seeds in planting trench, water after casing to guarantee SAP in water stored state.

TIPS
●  SAP shall be applied at the root.
●  Don't expose SAP in the air, as the O2 in the air can make the SAP degraded.
●  SAP can't make water, it is effective as drought-resistance agent only in the case of a small amount of water.
●  If in dry method, watering thoroughly. If without watering condition, wet method is suggested.
●  No matter in dry or wet application, SAP must be mixed evenly with ditch subsoil to avoid water excessive concentration.
●  Due to the difference of regional soil, climate and drought conditions, application shall be based on the actual situation.
