Super absorbent polymer (SAP)
SAP is a kind of eco-friendly material with strong water absorbability.
It can absorb plenty of water and will be bigger into gel form to lock water.
Super absorbent polymer for agriculture
Super absorbent polymer for agriculture also called potassium polyacrylate or Ag-SAP can help plants retaining water. We can consider it as a “mini-reservoir “.
There’re some differences from another SAP type,
- Its potassium polyacrylate is the main ingredient. (The other type sodium polyacrylate will cause soil salinization)
- Auto to release water. Ag-SAP’s water-holding ability is stronger than soil’s but weaker than the root of plants’.
- Repeatedly absorbing & releasing in soil. Ag-SAP can get the water-absorbing ability again after releasing the absorbed water.
- Long lifetime. Ag-SAP will live in soil for months. (the SAP gel in diapers will disappear in one week in soil.)
