  ABSTRACT: The forms of organic “Po” and inorganic “Pi” phosphorus in the soil, in addition to being influenced by phosphate fertilization, can also be in- fluenced by different soil management systems and cover crops. There- fore, the objective of this work was to evaluate the influence of soil mana- gement systems, cultivated with successions of crops in the forms of “Po” and “Pi”. The experiment consisted of two soil preparation systems (Direct Planting System—SPD and Traditional Planting—PRT) and two crop successions (soy/beans and Corn/corn + brachiaria), being evaluated in two layers (0 - 10 and 10 - 20 cm). The use of crop successions promoted the greatest accumulation of total phosphorus in organic forms, both in SPD and PRT. There was no difference between systems for total Po forms in the two layers and labile “Po” in the 0 - 10 cm layer. However, in the 10 - 20 cm layer, the PRT obtained the highest levels of labile “Po”. The inorganic forms of total phosphorus were higher in the 0 - 10 cm layer compared to the 10 - 20 cm layer in both systems evaluated. The SPD promoted higher levels of labile “Pi” in the 0 - 10 cm deep layer. As for PRT, there are higher levels of labile “Pi” in the 10 - 20 cm layer of the soil compared to SPD.
