Abstract
Seed coatings and methods of their use are described. The coatings comprise limestone or other water insoluble particulate matter which either includes a polymer in the limestone layer or a separate polymer coating on top of the limestone layer. The coatings may also include a coloring agent. The coatings offer the advantages of making the seed size more desirable and provide a more aesthetically pleasing appearance to the seeds.
