The problem we are facing now is that we are seriously low on moisture. Since the wheat is in the process of creating kernels it needs moisture to fill out the head as much as possible. In Brent's words "If we don't get rain soon, it's going to start affecting the factory". You can see in the below picture that the bottom of the wheat plants are starting to burn up and in general this wheat just doesn't look very happy.
You can see the difference that moisture makes in the below picture. All the dry land wheat outside of the irrigation pivot is burning up. All the wheat under irrigation is thriving.

P.S. If you have some extra rain laying around somewhere send it our way.
