The application of silicates to soils can result in increased soil cation exchange capacity (CEC), displace anions, especially H2PO4– (diacid phosphate), neutralize the pH and Al toxicity and, in general, increase the nutrient availability to plants. However, calcium silicates may be less efficient than calcium carbonates. To evaluate the effect of calcium carbonate substitution by calcium silicate on the soil chemical properties, especially on phosphorus availability, four experiments were conducted in an entirely randomized design with four replications, in a […]
