18. Potassium, pH, and Precision Soil Sampling: John Breker Pt. 2

Ag Geek Speak

Join us for an enlightening discussion with John Breker from AGVISE Laboratories as he shares cutting-edge insights into managing soils with low and high pH, plus insights on managing soil potassium. Discover how variable rate applications and the precision of zone and grid sampling can pinpoint soil pH variability within your fields, leading to more practical and accurate lime applications.
The conversation then broadens to address high soil pH levels and the crucial role of potassium in crop yield. John discusses the impracticality of large-scale pH reduction with elemental sulfur, suggesting more viable solutions like banding phosphorus and using chelated zinc starters. Additionally, he highlights the often-overlooked importance of potassium management, particularly in regions with fluctuating wet and dry cycles. This episode underscores the necessity of precision soil management in identifying specific areas needing attention, whether it's pH or nutrient issues, and how these insights can transform your soil management practices.
