Determination of total content of some microelements in soil using two digestion methods
Aqua regia and tri-acid digestion methods were applied for the analysis of some soil microelements. The total number of 243 soil samples was digested using the two different methods and total Iron, Manganese, Zinc, and Copper were measured in extracted solutions using atomic absorption spectrophotometer (AAS). The obtained results showed a strong correlation between two digestion methods of microelements, r=0.95, ... Read more
