Abstract:
Hydrogels is a substance which absorbs and retains water several times its own weight. Hydrgels are Super Absorbent Polyacrylatc (SAP) material. Hydrogels have potential in improving the productivity of Uganda's dry lands. When applied to the soil, as the soil dries
out, the hydrogel releases up to 95% of the absorbed water Hydrogels can also improve productivity of seedlings raised in the nursery by reducing costs of watering.
