What do all those numbers on a soil test actually mean?
In this episode of the Orchard People podcast, Susan Poizner speaks with soil educator Ariel Agenbroad about how to read a soil test for fruit trees and how to interpret results like pH, organic matter, nitrogen, and electrical conductivity.
Extension Professor Ariel Agenbroad has been working with urban farmers, gardeners and community members for over 18 years through University of Idaho Extension. Her love of plants, people and the natural world shape her programs and her approach to education. She is currently involved with a community orchard at Spaulding Ranch, a one of a kind historic agricultural park owned by the City of Boise.
Together, they explore how soil tests can guide your decisions—without overcorrecting or rushing to “fix” your soil.
You’ll learn:
- how to interpret soil test results in context
- why pH matters for nutrient availability
- what organic matter levels really tell you
- why nitrogen is difficult to measure accurately
- how to build healthier soil over time
