Oregon's estuaries are important ecosystems for scientific study. Consequently, knowledge of what research has been conducted helps us identify benchmarks and plan new projects. A comprehensive bibliography of published research, technical reports, local documents, and data sets is one means of recording this knowledge. For these reasons, the Guin Library...
Four surface and three subsurface horizons of agriculturally
important Oregon soils were exposed to excessive volumes of anhydrous
ammonia and reequilibrated with the atmosphere for several
time periods prior to extraction with water. The carbon solubilized
was determined by a modified wet combustion technique. Nitrogen
in the soils, extracts, and...
