Digging Deep: Understanding Soil Health and Fertility
In this episode of the Maine Farmcast, Dr. Colt Knight sits down with Dr. Jaime Garzon of UMaine Extension and Dr. Leandro Vieira from Louisiana State University to dig into what really makes soil healthy. The trio explores the critical relationship between soil fertility, structure, and biology, from pH and organic matter to microbial diversity and grazing management. Dr. Vieira shares his journey from a ranching family in southern Brazil to soil science research in the U.S., while Dr. Garzon explains how Maine’s acidic soils and high organic matter present both challenges and opportunities for producers.
Listeners will gain a deeper understanding of why soil testing is the foundation of any fertility plan, how overgrazing affects both root structure and soil integrity, and why balancing nutrients is essential for forage production. With practical examples, lively discussion, and even a few Florida field stories involving hurricanes, gators, and raccoons, this episode blends science and humor to help farmers manage their land more effectively, one soil sample at a time.
