Barret was one of the most remarkable students I've taught in 40 years at @Universityofmaryland. A pioneer in subaqueous barb mccarthy. My alma mater, @MichiganStateUniversity, is lucky to have nabbed him!

Getting started on FoodShotGlobal #sulfur to Protein project in Africa. Soil fertility to enhance methionine. Conducted "job interview" over soft drinks in tiny roadside shop. #Beans and #groundnuts are in bloom, so hope to do #onfarmtrials with foliar Epsom Salts next week.

Thanks @IsaacChavulau of Tiyeni, for showing me a few of the 1000’s smallholder farmers who have adopted their permanent deep-dug bed system, with contour-tied furrows and compost in planting holes. Video starts in standard ridged field and pans to Tiyeni photos.app.goo.gl/Smd8tDkdjJsRus…

Many #African ag #soils have a root-restrictive #plowpan at ~10-30 cm depth, often caused by annual tillage on wet soils. #Foodproduction is constrained by #water & ##nutrients available in 0-20 cm of soil.

Deeply loosened permanent planting beds require double the labor in year1, but are #notill (and no-step) thereafter. Crop yields are doubled in the first growing season and for years after, while labor is lower due to no tillage or ridge construction.

Sadly, yesterday #regenerativeagriculture lost a pioneer: Dave Brandt died in an accident. He was down to earth but looked to the stars. I gave #soilhealth talks to ~200 farmers at Dave's field day in 2015. Here's him showing his 30 yr #notill soil after 3" rain. Let us carry on!

Beautiful! Transitioning to #Organic #Grain (NIFA)-corn bioassays 3 years of transition strategies. Amazing #soillife compared to tilled bare soil. Timing & equipment adjustment! #PlantingGreen into Vetch-Rye #CoverCrop for Organic Corn youtu.be/Ju167AaO4rA via YouTube

Was worried about the long vetch vines wrapping around the planter wheels, but this wasn't a problem. Here's a close-up of the planter action (which was followed by rolling). Regenerative Organic Corn No-till Planting Green without Chemicals youtu.be/nc9WbjVyzZo via YouTube

ORGANIC REGENERATIVE FARMING #2: Soil Mulched & Full of Life as Organic ... youtu.be/qkbJikFpaF4 via YouTube 10 days after no-till planting in high biomass living cover crop, corn emerges through protective mulch. No rain but soil is moist, full of visible life. Feels right.

Stopping by the mailroom I saw this sign of a #soilartist hidden someplace in old HJ Patterson Hall! 🎨Beltsville silt loam tan, glauconite green, old #soilsurvey sample jars? Reminds me of when I found a handmade beta version of the Munsell #soilcolor book from the 1920s Bureau

#3 in #regenerativeag #organic corn without chemicals or tillage. Progressing nicely. youtube.com/watch?v=sg_MIe… Organic crop follows 4 transition strategies. But everything has to be right. Shot footage at the nearest (& best) of 4 farms. Corn at other sites looks fair to failure.

We often overlook the life beneath our feet. But tiny animals like dung beetles keep soil healthy and our food systems strong. 🌱 As #COP16Colombia begins, let's push leaders to #ActForOurPlanet and protect the life which sustains us. 🌍 #NaturesTechnicians

Removed from gas 50 years ago, legacy #lead still contaminates #forest #soils near roads. Tires also emit zinc to contaminate such soils. Zinc, not lead, bio-accumulated in #earthworms. College of Agriculture & Natural Resources Journal of Environmental Quality doi.org/10.1002/jeq2.2…
