Agriculture Soil Science

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.

Analyzers

Product	Model	Measurements
G2103 Gas Concentration Analyzer The Picarro G2103 gas concentration analyzer provides precise, real-time measurement of ammonia (NH3) and water (H2O) vapor. It incorporates coated components in the critical gas pathway. This reduces the propensity of NH3 molecules to adhere to pathway surfaces, which improves measurement response time.	G2103	Ammonia (NH3)
