A dry formulation for the growth enhancement of a seed comprises various nutrients, growth hormones, pesticides, and other beneficial and protective agents for the seed confined therein, in a particulate mixture of polymers including water-insoluble polymers such as polyacrylamide with hydroxypropyl methyl-cellulose, which upon moisture contact by rainfall or other irrigation means starts to slowly hydrate and form a controlled release gel, enveloping the seed to provide a protective zone for moisture retention and slow release of assimilable nutrients during the period of germination and development of the seedling. |
