Yes, sure. And good morning, Steve. Yes, to answer your question and follow-up with Ken's comments there. Number one, you mentioned variable rate and Steve, we don't do really today - we don't do a lot of blanket rates in P&K, a lot of it or the majority of it is variable rate. Most all of our application equipment today is set up, where we variable rate, and as you will know, we do a lot of it. We do extensive soil testing and running that analysis through Waypoint Analytical to come back with a proper prescription for nutrient needs. And so from that standpoint, as Ken said, we haven't seen cut back in rates. Obviously last fall, we had a tremendous run, last fall. And that's probably what slowed some things up in the first quarter, albeit, and if I look back at those rates, last fall, they were very strong rates. And I think in the environment that we're in today, Steve, these growers are going to give themselves every opportunity to maximize out on yield. We also think that once we get in season. We think our full-year nutritional products are going to be at a very high demand, and we've really stepped up production in those areas as well, because we think these growers will spoon-feed this crop throughout the season. We've seen a lot of demand for our infra-type pop-up products as well, Steve. So I think we're still in a very strong environment. Unlike anybody else here I'm ready to see this crop get put in the ground, and it looks like next week, talking to our climatologists it looks very strong, but we're going to be able to make a lot of planning progress going into next week. So we're anxious to get that started, and get things going. And Ken, I'll go back to you on the urea question.
