Accelerated Diffusion Methods for Inorganic‐Nitrogen Analysis of Soil Extracts and Water

Abstract The major limitation of diffusion methods for N analysis is the time required to obtain the results — typically from one to several days. Methods were developed that involve a much shorter period for diffusion. In these methods, 10‐ to 100‐mL samples of 2 or 4 M KCl soil extract or water we... View More
