About Soil in Chisago County, Minnesota
Chisago’s sandy, acidic profile
Chisago County has a pH of 5.53, making it more acidic than the state average of 6.21. This soil reflects the sandy glacial outwash plains found along the St. Croix River valley.
Sand-heavy soil structure
The soil is 61.0% sand, which creates a loose and easy-to-till texture. With only 9.5% clay and 27.6% silt, drainage is quick, but the soil has limited capacity to hold onto nutrients.
Modest organic matter levels
Organic matter sits at 7.64%, trailing the Minnesota average of 9.90%. The available water capacity of 0.172 in/in is also lower than the state benchmark, suggesting a need for consistent irrigation.
Fast-draining glacial plains
While official drainage classes are not listed, the high sand content ensures that water moves through the profile rapidly. This makes the land well-suited for development but challenging for water-intensive agriculture.
Garden tips for Zone 4b
Chisago’s Zone 4b climate is ideal for peppers and tomatoes if the sandy soil is enriched. Adding compost will help improve the 0.172 water capacity and support healthy root growth.
