What Soil Tests Miss: The Biology Driving Real Soil Fertility | Dr. Lance Gunderson

<p>If soil is the engine of agriculture, how do we measure its performance?</p><p>For decades, agriculture has treated soil like a chemistry set.</p><p>Measure nitrogen. Adjust phosphorus. Balance potassium.</p><p>But soil is not a sterile laboratory.</p><p>It is a living biological engine.</p><p>In this episode of <b>Soil Talks™ Podcast</b>, Brandon Kail sits down with <b>Dr. Lance Gunderson</b>, president of Regen Ag Lab and one of the most experienced soil microbiology interpreters in agriculture today.</p><p>With over <b>100,000 soil samples analyzed</b>, Lance explains why traditional soil tests often miss the most important part of soil function: <b>biology.</b></p><p>We break down:</p><p>• Why the soil microbiome controls nutrient availability<br />• The limits of conventional salt extraction soil tests<br />• How the <b>Haney Test</b> measures biological soil function<br />• Why fungal:bacterial ratios influence carbon storage and drought resilience<br />• The hidden role of <b>protozoa and microbial grazing</b> in nitrogen release<br />• The difference between <b>PLFA testing and DNA sequencing</b><br />• How growers can reduce fertilizer dependency through biological nutrient cycling</p><p>If soil is the engine of agriculture, this episode shows how to finally <b>look under the hood.</b></p><p>Because soil health isn't just chemistry.</p><p>It's biology, structure, water, and time working together.</p><hr /><p>🎧 Share, Like &amp; Subscribe to the <a rel="noopener noreferrer nofollow" href="https://www.youtube.com/playlist?list=PLEVD04wz0u2J9qqu3L0zcZ9V8_YVzpr81?sub_confirmation=1" target="_blank">Soil Talks™ Podcast </a><br />Hosted by <a rel="noopener noreferrer nofollow" href="www.rockymountainbioag.com" target="_blank">Rocky Mountain BioAg®</a></p><p>Contact Dr. Gunderson at <a rel="noopener noreferrer nofollow" href="https://regenaglab.com" target="_blank">https://regenaglab.com</a></p><p>Learn more with </p><p><a rel="noopener noreferrer nofollow" href="https://www.rockymountainbioag.com/collections/biological-beyond-organic-soil-health-courses/products/biological-beyond-organic-soil-health-course" target="_blank">The Biological...Beyond Organic® Fundamentals Course</a></p><hr /><p>#soilhealth #soilbiology #soilmicrobiome #soiltesting<br />#haney test #regenerative agriculture #soilfertility<br />#microbialnutrientcycling #plfasoiltesting #soilmicrobiology</p>
