Distribution of organic phosphorus in humus fractions has been studied. Maximum organic phosphorus has been fractionated with non-humus fraction, followed by β-humus, fulvic acid, humic acid and hymatomelanic acid. Humins did not contain phosphorus. Phosphorus associated with humus fraction is not interrelated except in case of fulvic acid and β humus which has significant negative correlation.
