Thanks. I continually recommend this book to anyone wanting to understand transforming family trajectory with a bucket of fertilizer, genetics, and simple agronomy.

To all proponents of #agroecology in Africa: Read this excellent book on four mothers heartbreaking choices between providing food, health and education to their children. All to be financed by a few bags of maize! 🙏🏻 Cry and review: amazon.com/Last-Hunger-Seaso…

The Last Hunger Season: A Year in an African Farm Community on the Brink of Change

At 4:00 am, Leonida Wanyama lit a lantern in her house made of sticks and mud. She was up long before the sun to begin her farm work, as usual. But this would be no ordinary day, this second Friday...

Let me post (with permission) two excellent slides @cropdetective (of @Woodrill and @UofGuelphOAC ) presented in a webinar this week. Same site, hybrids for 10 yrs. Until we better learn how to predict N needs by year in rainfed agriculture, efficiency of usage will remain modest

Do you think microbes in your manure, compost, or in their extracts, will help your soil? Think again. They often don’t adapt well to the soil’s habitats and don’t compete well with native microbes. My latest... csanr.wsu.edu/a-problem-with…

Corn on the left: 40 lbs N at planting + 170 lbs at V10. Corn on the right: 40 lbs N at planting + 170 lbs at V5. Greater tip back on the left and yield estimates as much as 30 bu/A lower. Highlights the importance of N timing and negatives of waiting too long. Southeast, IN.

No chance to remove CO2 from the atmosphere by sequestering carbon in arable land! Cropland soils have the lowest C stock. Let's conserve the C stock in the soils of other biomes! #CO2 #sequestration #soil #carbon #cropland #Vegetation

#Yara is implementing further curtailments which will take its total European #ammonia capacity utilisation to around 35%. With this, Yara will have curtailed an annual capacity equivalent of 3.1m tonnes ammonia &4m tonnes finished products across its production system in Europe.

We recently published a paper by Philip White, reviewing the role of Boron as a plant nutrient. It's free for Society Members to download: fertiliser-society.org/store…

Boron and Plant Nutrition

Boron (B) is generally present in both the soil solution and plant tissue water, as either boric acid (B(OH)3) or borate (B(OH)4-). Boric acid has a pKa of 8.92-9.24. Hence, boric acid is the major...

So they can only ship to non-humid locations? And why don’t they use an auger? So bizarre to see.

I was mesmerized watching them unload this barge of Urea- this could be headed to one of our #rice or #corn fields today!! They can unload one of these barges in 3 hours. #VTARAgTour
