摘要

The acids soils require lime materials to increase their pH and base saturation percentage. Soil acidity correction practice is restricted to limestone use. There is little information regarding the effects of others materials on soil amendment. This laboratory experiment was carried out to evaluate the effect of different materials on Ultisol, Oxisol and Entisol pH, as corrective material to amend acidity of acid soils, compared to common application of calcium carbonate and steel slag. Therefore, an experiment was conducted in laboratory, involving soils incubation treatments for 100 days. The treatments consisted of four corrective agents: rock powder, MB- 4, poultry litter biochars, silicate and calcium carbonate, evaluated by the base saturation method, with correction levels from 40 to 80% for Ultisol and Entisol and from 20 to 80% for Oxisol and in three replicates. After the incubation period the soil samples were chemically analyzed. The results of this study confirmed the effectiveness of poultry litter biochar, MB-4, silicate and calcium carbonate for improving the chemical properties of Ultisol, Oxisol and Entisol. The results indicated that the improvements of soil characteristics are changed with variations in the amount of corrective agents added to the soil and time of incubation.The results showed that pH increased significantly with increasing application rates of correcting agents, reflecting the fact that the liming potential increased with increasing application rates of corrective materials. The sequence order of greater efficiency in the neutralization of the acidity of the soil was calcium carbonate > silicate > MB-4 >biochar.
