Agriculture & Soil Science

How can we help you?

Agricultural soil science examines soil as a manageable natural resource affecting the development of plants responsible for food and fiber. Soil traits and related agricultural activities may influence, or be influenced by, greenhouse gas concentrations. With soil’s integral role in cycles such as nitrogen (N) and carbon (C), this science often seeks to measure soil flux—the exchange of gases between soil and the atmosphere—of methane (CH₄), carbon dioxide (CO₂), and nitrous oxide (N₂O). Monitoring methods include chamber techniques, micrometeorological approaches, satellite observations, and airborne surveys.
