The Sharp Edge: Sulphur strategies for higher yielding soybeans

Research from Purdue University agronomy professor Shaun Casteel indicates that early sulphur applications broadcast pre-plant or right at planting can deliver a soybean yield bump in specific conditions.
On the season debut of The Sharp Edge, Maizex agronomist Henry Prinzen takes that knowledge to the field to compare notes with Simcoe, Ontario, grower Kyle Sowden who participated in on-farm sulphur trials in 2023.
Last year, Maizex ran trials on five farms across Ontario and Quebec and saw a significant yield response to 100 pounds of ammonium sulfate (20 pounds of actual sulphur) at three sites, including Sowden's farm. That yield bump increased to up to 12 bushels for treatments that also included a fungicide and added nitrogen.
In the video, Prinzen looks at why some sites were more responsive than others. "For our responsive sites, we're looking at those lower CEC (cation exchange capacity) soils. They're probably sands, but they're not always sands. We had some mid texture soils that did respond. But for those really heavy clays and heavy loam - we didn't see anything this year."

Any guidelines to project how fast AMS will lower your pH? I love AMS in corn and wheat, but from what I’ve read it will lower your pH. Cuts into your potential profits if you need to use more lime. I’m hoping it’s negligible. Maybe ATS with the pre plant herbicide is an option? Although no guarantee ATS will play nice with those chemistries.
