Abstract: The objective was to compile and analyze soil chemical parameters related to the use of different phosphorus sources and microbial inoculants. A sample of a Dystrophic Red-Yellow Latosol was collected in the 0–0.20 m layer, in an agricultural area at Fazenda Nascente, MT. Two arbuscular mycorrhizal fungi, Ceratobasidium sp. and Tulasnella sp. genera, and a Bacillus mixture containing Bacillus megaterium and Bacillus subtilis were tested as inoculants. The arbuscular mycorrhizal fungi were registered under SisGen number (A028072). At the end of the experiment, part of the soil was collected, sieved (sieve <2 mm) and dried to obtain air-dried fine soil for subsequent chemical analysis. There was a significant effect (p<0.001) for the phosphorus source on most variables, such as soil pH, P, K, Ca, Mg, S, H, V, Fe and Mn. No significant differences were observed for Al, MO, B, Cu and Zn. On the other hand, the inoculant did not show significant influence for most variables, except for Mg, which showed a significant difference (p<0.05). To maximize the benefits of applying phosphate rocks and inoculants, it is essential to consider the particularities of the soil, the compatibility of microorganisms with the crop and the need for adjustments in management practices.
