Example Data Frame for total nitrogen (N) and available or mineralizable N in soil
Description
User is advised to prepare the data as suggested in the example to get the total N (when soil is digested with concentrated sulphuric acid in the presence of digestion mixture); or available or mineralizable N (when soil is distilled with alkaline potassium permanganate solution) in soil
Usage
df_N_Boric
Format
Data frame with Mass of soil sample (g) in the first column, Volume of standard sulphuric acid solution (mL) consumed in titration with soil in the second column, Volume of standard sulphuric acid solution (mL) consumed in titration without soil (i.e., blank titration) in the third column, and Normality of standard sulphuric acid solution in the fourth column. Write the following notations on the spreadsheet:
Mass_Soil - for Mass of soil sample (g)
Vol_Sulphuric_Soil - for Volume of standard sulphuric acid solution (mL) consumed in titration with soil
Vol_Sulphuric_Blank - for Volume of standard sulphuric acid solution (mL) consumed in titration without soil (i.e., blank titration)
Normality_Sulphuric - for Normality of standard sulphuric acid solution
