I'm reaching out regarding the availability of clay materials suitable for seed coating applications. Specifically, I'm interested in types like bentonite clay, but I'm open to exploring other options that might work well for this purpose. Could you provide more detailed information on the suitable clay types you offer? I'm looking for specifications, potential benefits for seed coating, and any other relevant details that could help in our decision-making process. Additionally, if you have samples available, that would be greatly appreciated. Thank you for your assistance!
