Answer 1

For nitrogen, the first step isconversion of organic nitrogen (N) in soil organic matter (SOM) to ammonium (NH4 +) by a process called ammo- nification. Often, the ammonium is rapidly converted to nitrate (NO3 –) by the microbial process of nitrification.

KJELDAHL’S METHOD

LET THE MASS OF ORGANIC COMPOUND TAKEN =w gram,

VOL.OF H2SO4 OF MOLARITY M TAKEN =V ml

V1 ml OF NaOH OF MOLARITY M

% of nitrogen = [1.4*M*2(v-v1/2)]/w
