Soil Scientist Career Guide,
Salary, Licence & Jobs 2026

Soil scientists are grouped under Soil and Plant Scientists (SOC 19-1013), where the BLS OEWS May 2025 median is $78,850 a year, about $37.91 an hour. Pay runs from $48,680 at the 10th percentile to $138,120 at the 90th, and soil scientists in senior research, federal or consulting roles, or leading survey programs, earn in the upper part of that range.

You earn a bachelor's degree in soil science, agronomy or environmental science with the required soil-science coursework, then gain field experience as a soil technician describing profiles and supporting surveys. Most soil scientists learn USDA soil taxonomy and GIS mapping, pursue the Certified Professional Soil Scientist (CPSS) credential and any state license their work requires, then advance into senior survey, research or program-lead roles.

A soil scientist studies and classifies soils and interprets what they mean for land use. That includes surveying and mapping soils, describing profiles in the field, assessing soil health, drainage and suitability, and advising on conservation, nutrient management, wetland delineation and development. Much of the profession works through or alongside USDA-NRCS, universities and environmental consultancies, combining fieldwork with GIS analysis and report writing.

It depends on the state and the work. The Certified Professional Soil Scientist (CPSS) credential from the Soil Science Society of America is a voluntary national standard, but several states license soil scientists — often for on-site wastewater, septic and land-use evaluations — with their own exams and experience requirements. Federal USDA-NRCS positions have specific coursework requirements rather than a license. Requirements should be checked state by state.

Both fall under SOC 19-1013 but differ in focus. A soil scientist studies the soil resource itself — classifying, mapping, surveying and assessing it, often for conservation, environmental or research purposes. An agronomist works with growers to raise crop yields through fertility, seed and crop-protection programs. Put simply, soil science centers on the land; agronomy centers on the crop grown on it, though the two overlap in nutrient and conservation work.

For people who like earth science, fieldwork and environmental work, yes: soil scientists earn a $78,850 median and can reach $138,120 in senior roles, and BLS projects 5.4% growth through 2034 with rising interest in soil health and carbon. It requires a science degree and, for some work, certification or a state license, and it blends outdoor survey work with GIS analysis and reporting, but the field is steady and mission-driven.
