Know Your Soil by Amigo Bob Cantisano

"Know Your Soil" is more than just a technical handbook—it reflects the lifetime of experience and passion of Amigo Bob Cantisano, one of America's greatest organic farming pioneers. Drawing on decades of consulting with growers, mentoring farmers, and shaping organic standards, Amigo distilled his hard-won knowledge into a practical guide for anyone serious about soil health.

The book demystifies soil chemistry and biology, showing readers how to interpret complex laboratory reports and translate them into on-the-ground practices. It offers clear, actionable advice for improving soil fertility by balancing major nutrients, fine-tuning micronutrients, and understanding the relationships between soil pH, trace minerals, and nutrient interactions.

Amigo’s work goes beyond the numbers—he shares insights into organic matter management, cover cropping, compost, compost teas, and the use of natural rock minerals, all grounded in his deep belief in regenerative practices. He also explains technical terms like Cation Exchange Capacity (CEC), Excess Lime Rate, and Estimated Nitrogen Release (ENR) in plain language, making soil science accessible to growers of all levels.

By blending scientific precision with the wisdom of a farmer-activist who dedicated his life to organic agriculture, "Know Your Soil" empowers readers to build healthier soils, more resilient crops, and profitable farms.
