Example Data Frame for available micronutrient cations in soils
Description
User is advised to prepare the data as suggested in the example to get the content of available micronutrient cations in soil based on atomic absorption spectrophotometer (AAS) reading.
Usage
df_DTPA_Micro
Format
Data frame with Mass of soil sample (g) in the first column, Volume of extractant solution (mL) in the second column, Volume of aliquot of the extract (mL) in the third column, Volume of final solution fed to AAS (mL) in the fourth column, Concentration of the micronutrient cation (mg/L) in final solution (test sample) as obtained from the AAS in the fifth column, Concentration of the micronutrient cation (mg/L) in the blank solution as obtained from the AAS in the sixth column. Write the following notations on the spreadsheet:
Mass_Soil - for Mass of soil sample (g)
Vol_Extractant - for Volume of extractant solution (mL)
Vol_Aliquot - for Volume of aliquot of the extract (mL)
Vol_Final - for Volume of final solution fed to AAS (mL)
AAS_Sample for Concentration of the micronutrient cation (mg/L) in final solution (test sample) as obtained from the AAS
AAS_Blank for Concentration of the micronutrient cation (mg/L) in the blank solution as obtained from the AAS
In case of no additional dilution after extraction, the values of Vol_Aliquot and Vol_Final should be put as 1.
