In this Podcast Extra episode, join John at Acres Eco Ag 2025, where he hosted a "Coffee with John Kempf" session, answering questions from the audience. In this episode, a wide range of topics are discussed, including:
The use of foliar-applied low-biuret urea to significantly reduce a crop's total nitrogen requirement .
The potential for amino acid forms of nitrogen to replace large amounts of conventional mineral nitrogen .
Why plants fail to absorb or metabolize calcium efficiently when soil boron levels are low .
Recommendations for conducting sap analysis every 7 to 10 days to identify nutrient needs .
Optimal spray timing and the "point of deliquescence" to keep droplets liquid on leaves longer .
The necessity of using clean water free of carbonates, such as rainwater or reverse osmosis water, for effective foliar sprays .
AEA's new product, Pinion, which stimulates the leaf microbiome and activates plant immune pathways .
Strategies for decompacting soil by building organic matter and mycorrhizal fungi rather than just chemical balancing .

About John Kempf John Kempf is the founder of Advancing Eco Agriculture (AEA). A top expert in biological and regenerative farming, John founded AEA in 2006 to help fellow farmers by providing the education, tools, and strategies that will have a global effect on the food supply and those who grow it.
Through intense study and the knowledge gleaned from many industry leaders, John is building a comprehensive systems-based approach to plant nutrition – a system solidly based on the sciences of plant physiology, mineral nutrition, and soil microbiology.
Support For This Show & Helping You Grow Since 2006, AEA has been on a mission to help growers become more resilient, efficient, and profitable with regenerative agriculture.
AEA works directly with growers to apply its unique line of liquid mineral crop nutrition products and biological inoculants. Informed by cutting-edge plant and soil data-gathering techniques, AEA’s science-based programs empower farm operations to meet the crop quality markers that matter the most.
AEA has created real and lasting change on millions of acres with its products and data-driven services by working hand-in-hand with growers to produce healthier soil, stronger crops, and higher profits.
Beyond working on the ground with growers, AEA leads in regenerative agriculture media and education, producing and distributing the popular and highly-regarded Regenerative Agriculture Podcast, inspiring webinars, and other educational content that serve as go-to resources for growers worldwide.
