[Dr. Jeremy Ross, Soybean Agronomist standing in a soybean field.] The question was, "How far do we carry irrigated soybeans?" In the past, you know, we've always said, you know, if your beans are touching in the pods, you know that's when we want to terminate irrigation.

But before Phil Tacker left, him and Dr. Francis, down in, at Monticello, actually did some termination study work and they're saying if you can get to six-point-five, which is typically once you, the beans are touching if you can go another ten to fourteen days past that and you've got, you know, moist conditions that you ought to be sufficient for terminating irrigation. [Picture showing polypipe in a soybean field. Slide - Continue irrigation 10-14 days after pods touch.]

So, what our recommendations have been in the past, we're extending that about another two weeks, trying to keep that soil moist. [Pictures showing polypipe in a soybean field and a soybean field with water between the rows.] Now if we've had pretty dry conditions and you go out there are you're at six-point-five and you've got dry conditions you're probably going to gain by going ahead and irrigating one more time.

[Dr. Jeremy Ross] You've already got the poly-pipe pulled it's going to cost you just a little bit more in diesel cost. But the data that they're showing, you're going to gain that back by applying that additional, that last, one last additional irrigation.
