Obtaining finely ground, homogeneous plant and soil samples for chemical analysis without cross contamination is a major concern when using direct combustion procedures for determination of total nitrogen (N), total carbon (C), and isotope-ratio analysis. A rollermilling device, using square glass bottles instead of round grinding bottles, was evaluated.(More)

The Meteorological And Range Safety Support (MARSS) system provides the Air Force and NASA safety and meteorological user communities at Cape Canaveral Air Force Station (CCAFS), Patrick Air Force Base (PAFB), NASA Kennedy Space Center (KSC), and Vandenberg Air Force Base (VAFB) with an integrated, responsive, and near real-time capability to analyze,(More)
Soil electrical conductivity (EC) is a useful indicator in managing agricultural systems, but tools for convenient and inexpensive measurements in the field are generally lacking. Handheld conductivity probes were designed to evaluate in-field naturally occurring and human-induced total soluble electrolyte levels in soil and water. The probes were used to(More)
