MinnesotaSoil Scientist License Requirements

Soil scientists typically need a bachelor's degree in soil science, agronomy, earth science, or a related natural science. Programs should include significant coursework in pedology, soil morphology, soil chemistry, soil physics, and soil classification. A graduate degree may reduce experience requirements in some states.

The American Registry of Certified Professionals in Agronomy, Crops, and Soils (ARCPACS), now administered by the Soil Science Society of America (SSSA), provides the primary national certification for soil scientists. SSSA offers the Certified Professional Soil Scientist (CPSS) credential. Many licensing states accept or require ARCPACS/SSSA certification as part of the licensure process.

Professional experience requirements for soil scientists typically range from 3 to 5 years depending on the state. Qualifying experience includes soil mapping, classification, interpretation, investigation, and evaluation. A graduate degree may reduce the required years of experience by 1-2 years in some jurisdictions. At least a portion of the experience must be under supervision of a qualified soil scientist.

Approximately 15 states require licensure or certification for soil scientists. In states without licensure requirements, soil scientists may still practice but often obtain ARCPACS/SSSA certification for professional credibility. The specific credential title varies by state (CSS, PSS, PSC, SE, or PG-SS).

Soil scientists provide expertise in soil mapping and classification, wetland delineation, septic system site evaluation, environmental site assessment, land use planning, and erosion control. The specific scope of practice varies by state and may overlap with other licensed professions such as geologists, engineers, and environmental scientists.

CE Details

No CE explicitly required for state license renewal in Minnesota; SSSA CPSS certification maintenance requires 30 hours every 2 years

Regulatory Board

Soil scientist licenses must be renewed on schedule with the governing authority. Continuing education requirements vary by state, typically ranging from 10-24 hours per renewal period. Some states require specific topics such as soil science advances, environmental regulations, or wetland science. Maintaining SSSA certification may also require ongoing professional development.

Reciprocity Requirements

• •Active soil scientist license/certification in good standing from another state
• •Bachelor's degree or higher in soil science, agronomy, or related field
• •Meet Minnesota's education and experience requirements
• •Submit endorsement/comity application to the Minnesota Board of Architecture, Engineering, Land Surveying, Landscape Architecture, Geoscience and Interior Design (AELSLAGID)

States with soil scientist licensure may offer reciprocity or endorsement for practitioners holding licenses in other states. ARCPACS/SSSA certification is nationally recognized and portable across all states, providing a baseline of professional credibility regardless of state licensure requirements.
