Does the Supply and Demand Change for Agricultural Chemical Companies During a Drought?

I have been trying to figure out a way to ask different agricultural chemical companies how their supply and demands have been changing as the majority of the United States has faced this drought, but none of the ways I have thought of seem to be eliciting any type of response. Can anyone help me come up with an idea on a proper way to ask them for this bit of information without it coming across badly? Apparently just simply asking that question directly is not the right way to ask, so I figured reaching out here may be helpful. Thank you all in advance!
