Organic nitrogen chemistry

Witryna1 sty 2013 · 1. Introduction. Organic nitrogen (N org) is an important constituent of soil organic matter (SOM) and, as such, plays a key role in soil N cycling and crop production.Indeed, the mineralization of N org produces microbe- and plant-available forms of N which, in turn, participate in reactions that yield N compounds of concern in … The Kjeldahl method or Kjeldahl digestion in analytical chemistry is a method for the quantitative determination of nitrogen contained in organic substances plus the nitrogen contained in the inorganic compounds ammonia and ammonium (NH3/NH4 ). Without modification, other forms of inorganic nitrogen, for instance nitrate, are not included in this measurement. Using an empirical relation between Kjeldahl nitrogen content and protein content it is an important method for anal…
