Brown County features Entisols with a pH of 5.69, which is significantly more acidic than the national 6.5 median. This acidity is a defining characteristic of the region's rugged, forested hills. While it ranks lower with a 61.6 soil score, it is perfectly suited for native woodland ecology.

The State's Highest Silt Percentage

With a massive 68.6% silt content, this soil has a very fine, flour-like consistency. Combined with 15.2% clay and 16.2% sand, this soil is prone to erosion on the county's famous slopes. Careful ground cover management is required to keep this silty soil in place.

Vital Moisture for Steep Terrain

Available water capacity is high at 0.209, providing a critical reservoir for the county's dense forest cover. Organic matter stands at 2.40%, which is above the 2.0% national average despite being lower than the Indiana state average. This moisture retention is the lifeline for the local ecosystem during dry periods.

Managing Runoff in the Hills

Drainage data is limited, but the combination of high silt and steep topography typically leads to rapid surface runoff. Mulching and terracing are highly recommended for any local gardening projects. Protecting the soil surface is essential for maintaining the health of your land.
