The Geospatial Laboratory for Soil Informatics primarily focuses on data analysis and collaborates with other laboratories on the Iowa State University campus for soil property measurements, many of which are here in our department. Within our laboratory, we house the following research equipment:

Laser Diffractometer

• Capable of measuring particle sizes between 0.01 – 3,500 μm.
• Particle size measured across 101 bins for a highly detailed measurement of the particle size distribution.
• Accuracy: 0.6%

Our lab offers sample analysis at a rate of $10.01/sample for Iowa State laboratories or $12.01/sample for external organizations. Before providing us with the samples, they should be prepared by drying, grinding, and passing the sample through a 2mm sieve. For inquiries about this particle size analysis, please contact millerba@iastate.edu.

Virtual Server

A server equipped with a 16 core Xeon processor, supporting specialized software that includes:

  • ArcGIS
  • R
  • SAS
  • Anaconda
  • Adobe Creative Cloud


Shared Resources

We readily cooperate with other labs for the collection and analysis of soil samples. Our department has an in-house Soil and Plant Analysis service lab. We also work with other labs for more specialized soil property measurements. One of our shared resources is a Giddings probe mounted on a truck.
