Soil and enriched FYM test labs in Tamilnadu

Would like to know any test labs available in Tamilnadu to test Micro/Macro nutrients in our farm soil, enriched farm yard manure (FYM) and other organic inputs we feed in to our banana farm.  We tried in a lab in Karur dt but they are limited only to soil test (N-P-K only).

Appreciate if someone can a lead/direction.

Thanks
Siva

You can try TNAU in Coimbatore, they seem to test for micro nutrients.
