Abstract
Being able to measure total nitrogen (TN) is important for following the nitrogen budget. In this chapter, we present the spectrophotometric method we use for determining TN. The method relies on oxidation and reduction steps, involving persulfate digestion of nitrogen compounds into nitrate followed by spectrophotometric determination.

There are three corrections for this chapter. On page 90, 12th line from top should read as ‘(see step 6) with ultrapure water (e.g., 0.1 ml’ instead of ‘(see step 6) with ultrapure water (e.g., 1 ml’.
