Biogenic nitric oxide source struengths

摘要

Emissions of nitric oxide (NO) were measured during the summer of 1995 from four crops, located at three different sites thoughout North Carolina. These sites were chosen to represent major physiographic regions of the southeast U.S., in an effort to compare fluxes from different agriculturally managed soils. Emission rates were determined using a dynamic flow-thourgh chamber system. In order to understand the NO flux from the different soil and crop types, measurements were made on corn and soybean cropos in the coastal region, tobacoco in the piedmont region, and corn in the upper piedmont region of North Carolina.
