Management practices, such as tillage and cropping diversification, influence soil phosphorus (P) dynamics. The aim was to evaluate the long-term effect of tillage systems (no tillage, NT; vertical tillage, VT; conventional tillage, CT) on total (TP) and extractable (Pe) soil P distribution under different crop sequences (corn–wheat/soybean, C–W/S; wheat/soybean, W/S; corn–corn, C–C; soybean–soybean, S–S). TP and Pe were measured up to 50 cm deep. The TP distribution was associated to soil organic carbon (SOC) (r =.89, p
