Part 1 of a 1/2 day training gave a broad overview and introduction to some basic soil characteristics: phases (solid, liquid, gas), texture, density, structure, reaction (pH), plant-water relationships, organic matter, and nutrients.  PART TWO   /   OUTDOOR DEMO

After some classroom discussion we went head out to into the ECHO Farm where we looked at soil profiles with different soil horizons to point out textural, color, density, and structural differences. Participants practiced determining soil texture by feel.

Special thanks to Dr. Landon Darilek for giving this presentation at the ECHO Asia Small Farm Resource Center in Chiang Mai, Thailand on 26 June 2020.
