Resumo: | Two laboratory experiments were carried out to evaluate the effects of sugar cane straw on soil acidity. Sugar cane straw residues were added on the surface of a Typic Harplortox in a polyvinyl chlorid (PVC) column at rates of 0, 20, 40, and 76 g kg-1, the soil was incubated to field capacity with distilled water and incubated for 0, 7, 14, 45, and 90 days. Soil samples were taken at 0-5, 5-10, 10-15, 15-20, and 20-25 cm depth. With the increase of sugar cane straw rates one verified the increase of soil pH CaCl2, and decrease of KCl exchangeable Al in the top 15cm soil layer. The contribution of organic compounds to Al detoxification incresead with increasing sugar cane straw rates. Wheat root elongation used as acid indicator plant increased with increasing sugar cane straw rates. Maximum root growth was about 15cm long in the soil after eight days for the highest sugar cane straw rate.
