AbstractIt has been one a fractioning of the organic phosphates according to the Krivonosova (1972) method on the horizons of several andosoils of Canary Islands. Is has been distinguisshed between the organic phosphates bound to compounds no-specific of the soil, fulvic acids, humic acids and humine. The dates obtained are studied in function of the sample's depth, evolution grade, vegetation. pH, percentage of sand, clay, carbon, nitrogen, alumine, A1/A1 + Si ratio and active inorganic phosphates of Fe, Al y Ca.
