Soil Nutrition Handbook: Understanding soil and soil reports

Soil Nutrition Handbook
Understanding Soil, Soil Tests, and the Foundations of Soil Fertility

Healthy soils don't happen by accident. They are built through understanding, observation, and informed management.

In Soil Nutrition Handbook, regenerative agriculture pioneers Mark Shepard and Gary Zimmer provide a practical guide to understanding soil health, interpreting soil test reports, and making better fertility decisions. Designed for farmers, ranchers, gardeners, and land stewards, this concise handbook distills decades of experience into an easy-to-use resource for improving soil function and agricultural productivity.

Readers will learn how to evaluate key indicators such as soil pH, cation exchange capacity (CEC), base saturation, organic matter, and nutrient balance, while gaining a deeper understanding of how minerals influence crop performance, livestock health, and long-term farm resilience.

Unlike conventional fertility guides that focus primarily on N-P-K recommendations, this handbook explores the principles of balanced soil fertility, regenerative soil management, and biological farming, helping readers understand the relationships between calcium, magnesium, phosphorus, potassium, sulfur, and essential trace minerals.

Whether you're reviewing your first soil test or refining an established fertility program, Soil Nutrition Handbook provides practical, immediately applicable guidance for building healthier soils, healthier crops, and more profitable farms.
