Seed Coatings

Seed Coatings Imerys talcs for improved seed homogeneity and integrity and seeding production

Imerys minerals make ideal seed coatings where they:

  • Improve seed flow rate and seeder application control
  • Improve the uniformity of seed size, making seed application more consistent and reducing over seeding
  • Reduce abrasiveness and planter equipment wear
  • Create a moisture barrier preventing premature germination of seeds in wet soils
  • Maintain moisture levels in seeds promoting germination in dry soils
  • Have a lower pH than limestone, reducing seed germination pH issues
  • Lengthen seed shelf life
  • Ensure right dose of coloring on seeds coat and that color film is even
  • Minimize coloring oiliness
  • Do not inhibit growth additives


Talc is also an excellent carrier for all types of seed additives such as fungicides, herbicides, and nitrogen fixing bacteria.

Recommended grades:

  • Luzenac 2
