About Soil in Kalkaska County, Michigan

Extremely Acidic Northern Forest Soils

Kalkaska County has a very low average pH of 3.88, making it one of the most acidic regions in the state. This is far below the national median of 6.5 and reflects the county's history of conifer forests and specialized soil development.

Balanced Texture for Northern Ground

The soil is comprised of 47.8% sand, 23.2% silt, and 15.9% clay. This creates a more substantial body than many other sandy Michigan counties, providing a better foundation for holding onto added nutrients.

Incredible Organic Matter and Water Storage

Organic matter is exceptionally high at 40.65%, which is double the state average. This results in a high available water capacity of 0.236 in/in, allowing the soil to retain significant moisture despite its high sand content.

Moisture-Retentive and Complex Soils

While drainage classes are not officially specified, the high organic matter and clay content suggest this soil holds water much longer than typical sands. This makes it a unique environment where drought resistance is naturally high.

Specialized Gardening in Zone 5b

The extreme acidity and high moisture are perfect for blueberries, rhododendrons, and other acid-loving plants in zone 5b. If you want to grow standard vegetables, significant soil amending will be the secret to your success.
