So what about out west? And so, uh, Brian or Katie.

So we- we're seeing moreUh, culture rigs running in cotton ground, which I like to see.
43:28
So we're seeing more and more that allows for a liquid or dry culture rig.
43:32
So, you know, anytime you get that nitrogen below the ground, that, that for us is a benefit over losses.
43:38
Um, dry versus liquid, we've got some no-till that's heavy residue, and so in heavy residue, if we're dry as far as the environment, the urea tends to play better than liquid.
43:51
Liquid tends to get trapped on that residue and no amount of NBPT holds it, and so our losses are greater.
43:57
Uh, and even on bare soil, i- i- a bare soil, it's a easier mix.
