And Out Of Mind. A very high percentage of the applied NH3 is never used by the crop. This is more do to timing. Into the rivers, the drinking water creating a horrendous environmental problem. NH3 must be applied very accurately to protect an environmental problem.
Coolers magnify inaccurate application and create significant environmental problems.
Not really is this the case. But something did go wrong . The early designs of NH3 application systems used internal coolers that vented the vaporized NH3 into the manifold and not directly to the openers. Port to port variance was not good but N was cheap. Can you believe nitrogen only cost 2 to 3 cents per lb.
