Soil Scientists

We Dig Deeper

We promote the understanding and wise use of Minnesota's soil resources.

Established in 1973, the Minnesota Association of Professional Soil Scientists (MAPSS) is the only organization representing the professional interests of soil scientists in Minnesota. Our members consist of professional soil scientists, consultants, researchers, teachers and students, as well as those who just have an interest in soil.
