Sustainable Soil Management by Preston Sullivan is a practical ATTRA publication that helps growers understand the core principles of soil health and the steps needed to build and maintain healthy soils over time.
The publication explains that soil is far more than simply a growing medium for plants. Healthy soil functions as a living ecosystem made up of minerals, organic matter, water, air, fungi, bacteria, earthworms, and countless other organisms that work together to support plant growth and nutrient cycling. Managing soil health requires balancing all of these biological and physical processes in ways that support long-term productivity.
