Soil Quality in Marion County

via SoilByCounty

Acidic Silt Loams in Marion County

Marion County is dominated by Alfisols with a pH of 6.19, which is notably more acidic than the national median of 6.5. This silt loam profile is a staple of the region, though it may need lime to boost performance for certain crops.

Fine Texture and Nutrient Storage

The soil consists of 56.7% silt and 25.5% clay, making it very fine-textured and excellent for nutrient storage. Because it only contains 16.7% sand, it can be prone to compaction and may feel slick when wet.

Competitive Water Capacity

At 3.06%, the organic matter is lower than the Iowa state average but still significantly better than the national average. The available water capacity of 0.194 inches per inch is nearly identical to the state average of 0.195.

Navigating Poor Drainage and Saturation

Rated as poorly drained with a hydrologic group C/D, this soil struggles to move water and often remains saturated. These conditions are challenging for basements but excellent for moisture-loving plants and wetland restoration.

Powerhouse Soil for Diverse Crops

Hardiness zone 5b allows for a diverse garden of squashes, beans, and orchard fruits. Despite the heavy drainage, this moisture-retentive soil is a powerhouse if you manage the water levels correctly.

Lawn Care in Marion County

via LawnByCounty

Excellent Conditions in Zone 5b

With a lawn difficulty score of 81.3, Marion County offers some of the best growing conditions in Iowa. It outpaces the state average of 77.2 and the national median of 50.0, rewarding gardeners with high success rates.

Warm Summers and Ample Rain

The county experiences 20 extreme heat days per year, which is higher than the state average and requires extra summer vigilance. However, 36.9 inches of annual precipitation and 3,279 growing degree days provide strong support for rapid turf development.

Managing Silt Loam Drainage

The soil is a silt loam with a 6.19 pH, but it is classified as poorly drained. Homeowners should consider core aeration or surface grading to prevent water from pooling and suffocating grass roots during wet seasons.

Brief and Manageable Droughts

Only 5 weeks of drought occurred over the last year, showing that severe dry spells are rare in Marion County. While 100% of the area is currently abnormally dry, the soil's moisture-retention properties help protect turf from immediate damage.

Long Growing Season Ahead

The frost-free period runs from April 20 to October 19, providing a very generous timeframe for seeding. Choose heat-tolerant cool-season blends to help your lawn withstand the 20 days of peak summer heat.
