Abstract

Total nitrogen in twelve fertilisers was determined by three methods. Coefficients of variation obtained from replicate analysis showed that the modified comprehensive nitrogen method produced the most precise results. The method is suitable for determining total nitrogen in fertilisers containing unknown nitrogen sources and a large proportion of chloride to nitrate.
