Interviews include noted golf course superintendents, industry experts, agronomists and business people. These conversations are designed to inform and entertain. EarthWorks has been a leader in the discussion of Biological Soil Management and has been producing professional grade carbon based fertilizers for over 30 years. Each year over 15,000 soil tests are performed by the companies agronomists and all of this builds the focus of The EarthWorks Podcast.

Lawrence explains how humic substances moved from being poorly understood and difficult to label to becoming widely used for improving nutrient bioavailability and fertilizer performance. The discussion explores rhizophagy, the process through which plants cultivate microbes, bring them into their roots, extract nutrients, and release them back into the soil to repeat the cycle. Lawrence and Joel also examine the importance of enzymes, trace elements, carbon diversity, micronization, and complex product formulations in creating biologically active soils and longer-lasting turf responses. The central message is that reducing fertilizer inputs requires more than simply applying less product. It requires changing the soil system so microbes, chemistry, and physical soil conditions work together more efficiently.
