Abstract

This paper deals with an experiment carried out in pots with the aim of studying the fixation of P in a Dark Red Latosol, from the Municipality of Piracicaba, State of Sao Paulo, Brazil. The main conclusions were as follows: a) about 90% of the fixed P remained soluble in 0,05N H2SO4 solution; b) Fe and Al contributed to increase the quantities of fixed P; c) the pre-treatment of the soil with Ca(H2PO4)2. H2O decreased its capacity for fixing P.
