The P recommendations in Northeastern Brazil are based on research carried out in the decades of 70 and 80, being necessary a modernization in this recommendation, to focus the maximum capacity of P adsorption. Therefore, this work aimed to evaluate agroindustrial sugarcane characteristics in soils in function of phosphate fertilization. Five experiments were carried out at Pernambuco State Forest Zone Region. The soils were: Argisoil Yellow distrocoeso (PAdx); Latosoil Yellow distrofic (LAd); Argisoil Yellow distrofic (PAd); Gleisoil haplic eutrofic (GXve); and Espodosoil carbic duripanic (ESKo). The treatments consisted of seven P doses, determined in function of the maximum adsorption capacity of P. The experimental design was a completely randomized block, with four replications. The sugarcane variety RB863129 was used in PAd, LAd, GXve and EKo soils and RB855536 on PAd soil. The P fertilization increased agricultural and industrial productivities. Total recoverable sugar (ATR) values were not affected by phosphate fertilizer, being more elevated in soils with higher maximum adsorption capacity of P.
