The super absorbent polymer (SAP) is a biodegradable, starch-based material that can absorb and retain large amounts of water, improving soil moisture and nutrient levels. It is easily mixed into soil and operates by absorbing and then releasing water as needed by plants, ultimately enhancing water retention for years. SAP is beneficial for various plants, including medicinal and garden varieties, and helps prevent water loss, supports soil health, and maintains optimal conditions even in cold regions.
