In this Podcast Extra episode, John Kempf delivers his keynote address from "The Quality Edge: Market Differentiation Through Regenerative Wine Growing," an event hosted by Grgich Hills Estate in Rutherford, California. Speaking to an audience of professional wine growers, John explores how regenerative agriculture is becoming the ultimate differentiator in a crowded global market. He details how focusing on soil biology and plant physiology not only restores ecosystems but drives the production of wines with distinct character and superior quality that today's consumers demand.

Key Topics Discussed:

• Why wine grapes are one of the few crops where microbiome integrity translates directly to harvest quality and financial return.

• The "Rhizophagy Cycle" and how plant roots absorb entire microbial cells to extract nutrients.

• Recent discoveries that microbes act as "truckers", transporting lipids and nutrients into plants before returning to the soil.

• The concept of "quorum sensing" and how microbial communities behave as a superorganism once they reach a critical threshold of diversity.

• How trees and plants demonstrate intelligence and support one another through fungal networks, including the "Mother Tree" concept.

• The three major suppressors of soil biology: bare soil, high-salt fertilizers, and synthetic fungicides.

• Why synthetic fungicides are often more damaging to soil structure and biology than tillage or herbicides.

• Introduction to Pinion, a new biocontrol product from AEA that influences plant redox environments and activates immune pathways.

• The critical role of Manganese and Boron as bottlenecks for photosynthesis and sugar translocation.

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 .
