In this study, an experiment was conducted with the objective of evaluating the effect of dolomite and silicate on the chemical properties and nutrient availability in acid soils of Maynas, Iquitos. The experiment was developed using an incubation methodology in the Cañete laboratory. Different doses of amendments were applied: 2.5 t/ha, 5 t/ha and 10 t/ha of both dolomite and silicate, in addition to including a control treatment, represented by acid soil without amendments. The treatments were organized in a Complete Randomized Design (CRD) with three replications, resulting in 21 experimental units. Variables evaluated included soil chemical properties (pH, exchangeable acidity and effective cation Exchange capacity (E.C.E.C.)) and nutrient availability (phosphorus, calcium, potassium and magnesium). After three months of incubation, the results showed that both dolomite and silicate presented statistically similar behavior in terms of improvement of chemical properties. An increase in pH and C.I.C.E. was observed with increasing dosage, reaching values of up to 6.47 in pH and 7.76 mEq-g/100 g in C.I.C.E. with the application of 10 t/ha of amendment. In contrast, the exchangeable acidity of the soil decreased significantly, being reduced to 0.11 mEq-g/100 g with 10 t/ha. Regarding nutrient availability, it was evidenced that with the increase of the amendment dose up to 10 t/ha of dolomite and silicate, there was an increase in the concentration of cations, such as calcium (up to 1056.10 ppm) and magnesium (up to 254.60 ppm), as well as phosphorus, which reached 6.40 ppm.
