Thus, plots where grasses were inoculated in the crop rotation had 31.2% lower P content compared to non-inoculated plots, as well as decreases of 17.4% and 6.6% for K and CEC, respectively. Meanwhile, for m%, inoculated plots had higher values, with an \begin{table}

Still within this layer, P content was considered low, except at P\({}_{2}\)O\({}_{5}\) rates of 30 and 240 kg ha\({}^{-1}\), where it reached medium levels. CEC was high, OM was at medium levels, and pH was low. As shown in Table 17, referring to the 0.10-0.20 m soil layer, aluminum saturation (m%) was significantly influenced by the interaction between phosphorus rates and inoculation. Higher m% values were observed in non-inoculated plots at 0 and 240 kg ha\({}^{-1}\) of P\({}_{2}\)O\({}_{5}\), while inoculated plots showed increased m% at intermediate rates (particularly 120 kg ha\({}^{-1}\)). These results underscore the nuanced effects of inoculation and fertilization depth-wise. Across this layer, potassium (K) was the only attribute significantly reduced by inoculation (by 10%), while organic matter (OM) content increased by 9.1%. Other attributes were not significantly affected. The P content was still considered low, CEC remained high, OM showed medium levels, and pH was classified as low. The interaction between P\({}_{2}\)O\({}_{5}\) doses and inoculation with _A. brasilense_ significantly affected soil aluminum saturation in the 0.10 to 0.20 m layer. In the absence of inoculation, aluminum saturation remained constant across all P\({}_{2}\)O\({}_{5}\) doses, averaging approximately 7.5%. However, in inoculated areas, there was a quadratic response, with the highest aluminum saturation observed at the 120 kg ha\({}^{-1}\) P\({}_{2}\)O\({}_{5}\) dose (9.7%), and the lowest at the 240 kg ha\({}^{-1}\) dose (3.7%). These results suggest that inoculation with _A. brasilense_ alters the aluminum dynamics in the soil profile under different phosphorus fertilization levels (Table 18). Additionally, as shown in Table 17, for phosphorus rates in non-inoculated areas (breakdown), a positive exponential adjustment was found for P content (Figure 7), whereas no adjustment was observed in inoculated areas.
