Seven crops, staged and banded
The board and the relays are commodity. What a grower is short of is the answer to "what do I hold, when do I change it, and how do I know it worked" — and that answer is crop-specific, cultivar-specific, and for anything grown between March and June in an Indian polyhouse, climate-specific in a way no European recipe accounts for.

Every band on this site is a literature-derived starting point. None of them has been measured on your water, your cultivar or your polyhouse, and the variable that decides most of it — the alkalinity of what comes out of your borewell — is one this page cannot know.
