The factors on which the retention of phosphorus by peat depends were studied on the basis of a material of 134 virgin peat samples. The coefficient k in the Freundlich adsorption isotherm y = kcn was used as an indicator of the phosphate sorption. The association of k with the sampling depth, the degree of decomposition, weight of volume, pH, extractable calcium, and the iron and aluminum dissolved by 0.1 N hydrochloric acid was treated. The acid-soluble aluminum gave with k a highly significant correlation which did not decrease when the effects of acid-soluble iron and the degree of humification were eliminated. The correlation between k and the acid-soluble iron was also highly significant although less close than the former association...
