Soil Intelligence

Soil information is essential for addressing critical agricultural, economic, ecological, and environmental challenges. Our work advances these efforts by integrating geospatial technologies, data analytics, and soil science. 

Soil Survey in Iowa

The Iowa Soil Survey documents the state’s diverse soils through detailed mapping and classification efforts. It provides data on soil properties, formation, and distribution to support research, land management, and conservation. This resource is vital for understanding Iowa’s agricultural potential and guiding sustainable land use practices.

Soil Resources of Iowa

Iowa’s soil resources are dominated by deep, fertile Mollisols formed under prairie vegetation and glacial deposits, making the state one of the most productive agricultural regions in the world. Variations in glacial till, loess, and alluvial parent materials create differences in drainage, texture, and erosion risk across the state. While these soils strongly support corn and soybean production, they are vulnerable to erosion, loss of organic matter, and nutrient runoff, necessitating the implementation of conservation practices to maintain long-term soil health.

Corn Suitability Ratings & Soil Interpretations

Perhaps one of the most heavily used soil interpretations in Iowa, this index synthesizes several soil properties to rate the inherent ability of soils to support crop productivity, with corn specifically in mind. The current version of this rating (CSR2) serves as the basis for assessing approximately $1 billion in taxes on agricultural land.

Soil Erosion & Conservation

Soil erosion and conservation are especially important in Iowa because the state’s highly productive soils are the foundation of its agricultural economy. Erosion from water and wind reduces a soil’s resiliency in supporting crop production through adverse weather and economic conditions. This information should guide conservation practices and sustainable land management to ensure the future productivity of Iowa’s agriculture.
