Soil chromatography is an incredible photographic process that reveals the mineral and organic composition of soil through intricate patterns. Originally developed by scientist Ehrenfried Pfeiffer, this technique helps visualize soil health in a way that is both scientific and artistic.

In this workshop, you will learn the cultural and scientific history of soil chromatography, review the process for making these remarkable images including safe handling of photochemistry, make a chromatogram you can take home, and learn how to interpret the results. This will be a hands-on learning experience.

This is a fun opportunity to blend art, science, and nature in a creative and educational experience. Space is limited, so reserve your spot now!

Overview
Soil chromatography is a photographic process that uses photochemistry to create images of mineral and organic components found in soil. This process was originally developed by soil scientist and biodynamic farming advocate Ehrenfried Pfeiffer to give farmers an accessible way to test soil health. In addition to visually demonstrating soil health, the resulting images, called chromatograms, create stunning patterns.
