Insights from our 2020 Data

We analyzed trends from 148 soil samples from Boulder, Weld and Larimer counties in Colorado. We found: 1. Soil Health Scores tend to decrease with increasing pH, and increase with increasing water availability. 2. Loam and sandy-clay-loam soils tend to have higher Soil Health Scores than clay or sandy soil, but are relatively rare here. 3. Excessive phosphorus levels are a problem for growers using frequent manure amendments, especially organic growers and home gardeners. 4. Soil Health Scores and soil organic matter tend to increase as days of living cover increase. 5. Growers who test their soil in the fall tend to have higher Soil Health Scores than growers who test their soil in the spring.
