What is formula for estimating soil nitrogen from soil organic carbon

[@chidiorieke6002]

Dear Ma, I have a question and need help: I have weighed 1.0153g of a sample and digested with 20 ml of acid mixture, then after digestion, distilled water water added to make up the volume to 250 ml. Then 25 ml of the sample solution was taken and titrated against 0.01 N EDTA and 0.2 ml of EDTA was used to get the end point, to calculate the Calcium content and the formula I should use

[@shantigoka1894]

Please take the same quantities as explained, such minute quantities may have calcium or magnesium only in traces

[@koushikdas9534]

Ma'am can you give me the reference of this methodology
