Who should write, who shouldn't, and what happens after.

Write to us if you found an error in something we published, if you want to talk about the full product, or if a source we cited is broken or out of date. This form does not reach a sales queue with a script. A person reads every message.

We do not run a support desk for agronomic questions. If you are looking for calibration or dosage advice, that is not what we publish or what we answer here, and that is by design.
