Simple methods are described that permit the use of either H3BO3 indicator solution or acidified filter disks to collect NH3 liberated by treatment of Kjeldahl digests with NaOH. These methods incorporate modifications to improve reliability, analyti

Agricultural and natural N cycling systems have been intensively studied via the stable isotope \U15\NN. Tracing N translocation over time by applying \U15\NN-tagged fertilizer has been used extensively. Our objective was to quantify fertilizer \U15\

A microwave digestion procedure recently proposed for total N analysis of soil using HF-HCl, H₃BO₃, and H₂O₂ was found to give much lower values than conventional Kjeldahl digestion in analysis of soil and plant samples and simple organic N c
