[00:00:00]Hey guys, what's up? Garrett Williams agronomist for Advanced Analytics here in Southeast Illinois and Southwest Indiana.

[00:00:06]What you got behind me is a field of corn. Today we're looking at corn in Southeast Illinois.

[00:00:11]And right now is a really good time to begin to investigate really the importance of different fertility levels in our crop. And um what we're looking at today is phosphorus and phosphorus availability.

[00:00:24]Now it's really a good time to do so, especially as we look at the calendar and really look at the temperatures that we've experienced here in Southern Illinois and Southern Indiana over the last week and a half to two weeks. We've seen a slowing of growing degree days and a cooling of the soil temps and a cooling of the air temps, which really is going to begin to limit the uptake of phosphorus in our plants. And now's a good as time as ever to get out here and begin to investigate the differences in our phosphorus availability. And really this drives decisions, key decisions as we go into the fall and next spring as we begin to invest dollars in the dry fertility, albeit a very expensive dry fertility, you know, conditions remaining the same.

[00:01:04]But it's a good time now to begin to see these plant differences. And the picture that I'm going to show you guys really highlights that. This is what Advanced Analytics would characterize as above critical level and below critical level fertility levels for phosphorus. And we'll begin to or we'll continue to follow up with these different locations of fertility levels across the season and check in and kind of see what the developmental differences are and really drive these decisions going into the fall around dry fertility. So, Advanced Analytics unique methodology allows us to characterize spatial critical level in phosphorus and potassium by taking into consideration the influence of various moisture levels across the field, otherwise known as soil wetness index, and its role in diffusion of P and K in each respective environment.

[00:01:48]This permits us to adapt our P and K needs by environment based on the likelihood of its availability rather than attempting to build each acre to a standardized goal as found in the Illinois and Tri-State Agronomy Handbooks.

[00:01:59]So, uh if you want to learn more about this or continue to follow up on our conversations and our journey this summer, uh be sure and like and uh follow. Thanks.
