ABSTRACT
Abstract The objected to evaluate the pH and soil base saturation (V) values, during 45 months after, surface application and without incorporation of the liming materials in deeper layers of soil. The experimental design was completely randomized blocks in split-plot with four replications. In the plots were studied the dolomitic limestone (DL) and micronized liming materials (MLM) - granulated micronized calcite (GMC) and dolomite (GMD), and carbonated suspension (CS). In the subplots were studied doses of all the liming materials aiming to increase V to 50, 70 and 90% besides of control treatment. We measured the pH and V values in 0-5, 5-10, 10-20, 20-40 and 40-60 cm soil layers over time (5, 15, 28, 37 and 45 months). The MLM were more efficient to increase and maintain the pH and V, over time, than DL. The doses of MLM aiming V to 50-70% increasing the pH and V of Typic Distrudept. Despite the MLM are more fineness than DL, the effectiveness for soil acidity control in subsoil were inefficient, because theses pH and V increases/maintains occurred just in 0-5 cm layer. However, the MLM present lower gap between the V estimated and obtained, in the 0-5 cm layer, than DL.
