Banding P for Acidic Soils: Its not the time to be paying for poor practice.

With a spike in phosphorus fertilizer price and a short supply that will likely last through the summer. Wheat producers need to make plans now, and those plans should not include banding P for aluminum toxicity....

Got the chance to be on my 2nd favorite Extension Podcast, the MSU Mississippi Crop Situation. Which is only second to Red Dirt Agronomy Podcast. Alwasy have fun when I get to jump on the air ways with Jason and Tom. This time we talked biologicals, playing off the OSUNPK Blog. Go take a listen and make sure to subscribe to the Crop Docs. https://extension.msstate.edu/shows/mississippi-crop-situation .
And heres the link to the blog that started it. https://osunpk.com/2026/04/03/mechanisms-of-soil-fertility-looking-at-biologicals-and-moa/

Mechanisms of Soil Fertility: Looking at Biologicals and MOA As promised, here is the 3rd, can planned final blog diving into the mechanisms of biological products. I want to repeat from the last post, I believe that all products and methods have a place, so…

Green Peach Aphids Are Showing Up in Oklahoma Canola

Green peach aphids are showing up in Oklahoma canola—and they’re not one to overlook. Unlike cabbage aphids, these pests are harder to spot, behave differently, and can be more difficult to control. With dry conditions across much of the state, now is the time to scout fields, confirm identification, and evaluate thresholds before making management decisions. This latest OSU Extension update breaks down: • How to correctly identify green peach aphid • Where to scout and what symptoms to watch for • When treatment is actually justified • What products are still effective given resistance concerns Don’t guess—know what you’re dealing with before you spray....

Mechanisms of Soil Fertility: Looking at Biologicals and MOA

As promised, here is the 3rd, can planned final blog diving into the mechanisms of biological products. I want to repeat from the last post, I believe that all products and methods have a place, somewhere. But there is nothing suited for every field and year, including traditional commercial fertilizer. I hope my approach makes sense to most. On a side note, we are about to sumbit two manscripts about biologicals in cotton, when those are published we will turn the papers into blogs....

The Mechanics of Soil Fertility: Use of Sugar in Field Crops

I believe that all products and methods have a place, somewhere. But more so, there is nothing suited for every field and year, including traditional commercial fertilizer. To place the right practice in the right situation, the user needs to understand the management mechanism. This is as true for crop nutrition as it is IPM....

Mechanics of Soil Fertility: Understanding Humic and Fulvic Acids

While I am probably a dollar short and a day late, the latest hike in fertilizer price has a lot of folks looking for option B, C, and D. Over the next week I will be releasing blogs on the mechanisms of many of these products of interest, starting with Humic and Fulvics, following up with Sugars, and then Microbials. To get ROI from any of these products, you should know the mechanism of their function. Allowing you to use in the appropriate situations and not have inflated expectations....

Limited well capacity = limited yield… but not equally across hybrids.
Our 2025 OK Panhandle data shows yield losses accelerate below ~60–65% ET, with hybrid and population still influencing outcomes.
