About Soil in Morrison County, Minnesota
Acidic Entisols in Morrison County
Morrison’s soil is dominated by Entisols, which are relatively young and undeveloped soils. With an average pH of 4.92, these grounds are significantly more acidic than the national median of 6.5 and the state average of 6.21.
High Sand for Easy Workability
The soil profile consists of 54.7% sand, 24.9% silt, and only 8.6% clay. This high sand content ensures the ground is easy to work but requires careful management to prevent rapid nutrient leaching.
Exceptional Organic Matter Levels
Organic matter is exceptionally high at 14.88%, well above the state average of 9.90%. This boost in carbon helps maintain an available water capacity of 0.200 in/in, keeping the soil productive despite its sandy texture.
Excessive Drainage Requires Water Management
The land is classified as excessively drained, meaning water moves through the profile very quickly. While this prevents pooling after heavy rains, it also makes the soil prone to drying out during peak Minnesota summers.
Cold-Hardy Gardening in Zone 4a
In Hardiness Zone 4a, cold-tolerant crops like raspberries and potatoes thrive in this high-organic, sandy environment. Residents should take advantage of this unique fertility and start a garden today.
