Description: The application of calcium carbonate micron particles in the planting furrow, because of the reduced particle size may favor a faster reaction in the soil and could provide increased pH and P availability for plants such as dry bean (Phaseolus vulgaris L.), potentially increasing yield. A field experiment was conducted for two consecutive years with the objective to evaluate the effect of the liquid calcium carbonate micron particle application in the planting furrow on soil properties (Ph, P, Ca, K and Al content and V) and on the yield components, grain yield, and concentration and content of P in dry bean. The experimental design was a randomized complete block scheme. The treatments consisted of six rates of calcium carbonate micron particles, that is, 0, 1.05, 2.10, 4.2, 8.4 and 12.6 kg ha-1 applied in the furrow at sowing of dry bean. Calcium carbonate increased the pH (from 4.8 to 5.3 at 0 to 0.10 m deep layer) and the P concentration in the soil (from 70 to 80 mg dm-3 at 0 to 0.10 m deep layer) until 30 days after application. The concentration of Ca, K and the base saturation of the soil were not affected by the addition of calcium carbonate. The concentration (from 4 to 4.3 g kg-1) and content (from 1,500 to 1,870 g ha-1) of P in the grain and grain yield (from 3,500 to 4,100 kg ha-1) of the dry beans increased with increasing concentration of calcium carbonate. The use of calcium carbonate micron particles in the sowing furrow is a new and effective practice that could increase crop yield in no-tillage system (NTS).
