Soil Scientists - Main Soil Scientists Soil scientists develop methods to protect and manage soil.
Soil scientists look at all aspects of soil use, but especially at how it affects plant growth.
They study the physics, chemistry, microbiology, mineralogy, and fertility of soil. In addition, they study and change how soil is managed while growing crops. This includes how soils respond to fertilizer and crop rotation. Some soil scientists conduct soil surveys, where they classify and map soils. Using the results of their studies, soil scientists provide information to farmers and other landowners about the best use of land.
