@Eabfranc @ACESedu @AuburnAg Great study! I’ll be eager to learn your results. I’m reminded of our field trials in Eastern North Carolina destroyed by black bears. Maybe you can do that work next. Ha!

[Rob Mikkelsen @RobSoil]

@UMNNutrientMgmt @UMNExt @UMNswac Fabian is a great resource and wealth of information. This is so challenging to get right.

@TerryDaynard Andrew is a voice for clear- headed thinking in ag. His insights on this (and other topics on his blog) are always refreshingly honest.

@PankajTri29 @jordon_wade @WyoWeeds @WesternSugar @IgcastTtu Thanks for sharing. I look forward to reading it in detail. Your results may not be popular in some ag communities, but this information is so valuable.

@Eabfranc @ACESedu @AuburnAg Excellent visual demonstration on the effect of soybean variety on iron deficiency symptoms… and yield. Great work coming from your program!

[Rob Mikkelsen @RobSoil]

@Eabfranc @SoybeanScience1 @ACESedu @AuburnCSES Wow, beautiful “ugly” pictures. Thanks for sharing!

@agronomistag Great resource. Thanks for sharing. Misinformation abounds on so many topics like this. It's nice to have more facts.

Plus, consumed servings of fruits and veggies continues to drop.

@huckleberrypkr @agronomistag Where did you learn that glyphosate “kills all life”? That sounds like some hyperbole, which does not help the conversation progress.

@C4ClimatePol @agronomistag Where did you get this wrong idea? Geissler & Skow analyzed 64 long-term crop fertilization global trials- found application of mineral N fertilizer
associated with average 15% INCREASED microbial biomass and 13% INCREASED soil organic C compared to an unfertilized control.

@jjmcrops @NCSUCropScience Well deserved promotion and recognition.

It was a real honor to be asked!

@agronomistag Seems puzzling, but many believe that animals magically produce the nutrients and carbon in their manure. Manure is a great resource, but follow the origin trail. Thanks for the great reminders!

[Rob Mikkelsen @RobSoil]

@UMNNutrientMgmt Any way to fix the link? I'd love to read the article.

[Rob Mikkelsen @RobSoil]

@LuisAzcona @historyinmemes Huh, where did you get that idea? Plants can grow slowly in most any soil, but to have productive crop production, most soils benefit from adjusting pH or nutrient supply. It's not some conspiracy... known for millennia.

@DMandziak @YaraWesternCdn @dmandziak does such a great job developing innovative solutions to real-life farming issues. Thanks!

@coveryoursoil Thanks for sharing the pictures. How has yield held up with sulfur deficiency in past years?

[Rob Mikkelsen @RobSoil]

@LGatiboni Well deserved.

[Rob Mikkelsen @RobSoil]

@DrLimnology Squandering valuable resources.

@FertilizerSoil Of course there will always be fertilizer imports in some of the 54 African conference countries. Did anyone suggest that each country be self sufficient within its borders?
