Easy to know super absorbent polymer for plants

*This article is about super absorbent polymer for plants, potassium polyacrylate, Ag-SAP, water-retaining agent.

Super absorbent polymer (SAP)

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.

Types of SAP (by usages)

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. . .

Super absorbent polymer for plants

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.

waterside, it can absorb and store water for plants – like a mini-reservoir.

soil side, it can

improve the retention of soil and water;

keep the soil warm (as water’s high heat capacity);

loosen the soil (ag-sap’s going to swell while absorbing).

fertilizer side, it

contains potassium;

can release the fertilizer efficiency slowly.

Mainly applications

Common crops

To increase crops and fruit yield (increased 70% for melon planting in California).

Seed

To improve seed germination & emergence rate.

Gardening, horticulture, landscape, lawn, and golf course

To reduce the water frequency.

Trees

To increase the survival rate.

How to choose super absorbent polymer for plants

Class Main ingredient Basic retaining function Effective period Harmful substance
Fake ag-sap sodium polyacrylate no (no releasing water) ≤ 1 week acrylamide
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
Pack Rain-high qualities potassium polyacrylate yes 3-5 years none

annotations

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.
