| Calcium silicate when applied to the soil may cause changes in the chemical soil since it is a source of silicon, calcium and magnesium. The objective of this study was to evaluate the effect of calcium silicate on the chemical properties of an Oxisol. The experiment was conducted in a greenhouse with a randomized complete block design, with five doses of calcium silicate (0, 1.2, 2.4, 4.8 and 9.6 t ha-1) and four replicates. We evaluated the soil chemical properties. Silicon fertilization increases the content of Si, Ca and Mg, pH values, and SB and V%, and reduces the potential acidity (H + Al) of the soil. |
