Abstract
A Hydroseed substrate for mixing with other ingredients such as water, seeds, fertilizer, wetting agents and dye, to produce Hydroseeding slurry is disclosed. The substrate includes cellulose materials (e.g. cardboard, paper) and an absorbent. The absorbent is a superabsorbent polymer such as linear polyacrylamide (—CH2CHCONH2—) or copolymers of acrylamide (C3H5NO) polymers. The superabsorbent polymer improves moisture retention, improves viscosity, reduces friction, and improves coverage of the hydroseed mixture and germination of the seed.
