*This article is about super absorbent polymer for plants, potassium polyacrylate, Ag-SAP, water-retaining agent.
Super absorbent polymer is a powerful water absorption material.
One-gram SAP can absorb hundreds of grams' water.
After absorbing, powder from SAP comes into gel form.
SAP for Plants (Ag-SAP)
Just like a mini-reservoir, Ag-SAP can keep retaining & releasing water for plants.
SAP for Hygiene product
As a powerful absorption material, SAP is widely used in producing diapers, sanitary towels, nursing pads, etc.
SAP for Industry production
With strong modified potential, SAP can be used everywhere of production.
As a thermal insulation material: ice bags, ice towels, ice pillow, etc.
As a water blocking material: inflatable sandbags, waterproof for cable, etc.
As an expanding material: inflatable toy, inflatable rubber, etc.
As a moisture insulating material: concrete protection.
And so on. . .
Ag-SAP can increase the water holding capacity of soil by absorbing & releasing water in the soil.
Tips about super absorbent polymer for plants (Ag-SAP):
Ag-SAP's main component is potassium polyacrylate (not sodium polyacrylate);
Ag-SAP's valid period should be last for months;
Ag-SAP would be resolved into potassium, urea, water, and carbon dioxide.
How does super absorbent polymer work indeed?
waterside, it can absorb and store water for plants – like a mini-reservoir.
soil side, it can
fertilizer side, it
To increase crops and fruit yield (increased 70% for melon planting in California).
To improve seed germination & emergence rate.
Gardening, horticulture, landscape, lawn, and golf course
To reduce the water frequency.
To increase the survival rate.
|Class||Main ingredient①||Basic retaining function②||Effective period③||Harmful substance|

|Low-quality ag-sap||sodium polyacrylate||yes||1-3 months||acrylamide|
|Common quality ag-sap||potassium polyacrylate||yes||1-3 months||acrylamide|
|Common quality ag-sap||potassium polyacrylate||yes||≤ 1 month||none|

① "main ingredient", sodium polyacrylate will cause soil salinization (potassium polyacrylate won't);
② "basic retaining function" means water retaining & releasing ability;
③ "effective period" means how long is the Ag-sap working in soil;
④ "fake Ag-sap": profiteers sell fake Ag-sap cause the low price;
⑤ acrylamide: it's a kind of cancerogenic substance.
