Fertilization and liming, as well as the return of crop residues to the soil, are essential to prevent a rapid loss of organic carbon content from cultivated soils. Tropical and Temperate soils will likely respond differently to these amendments. An incubation study was designed to test the effects of corn, soybean, or no residue additons, with or without the addition of lime, on soil physical and chemical properties of two Oxisols (virgin and cultivated) from the Cerrados region of Brazili and a Mollisol and Inceptisol from Indiana. The soil properties measured at 0, 10, 20, 30, 60 and 90 days of incubation included organic carbon, pH, cation exchange capacity (CEC), water-stable aggregation, and water retention at -10, -33, and -100 kPa water potential. Carbon dioxide evolution was measured at short time intervals throughout the 90 days of incubation. The decrease in organic carbon content with time was in the order Inceptisol > Mollisol > Cultivated Oxisol > Virgin oxisol. Microbial activity, as measured by CO2 evolution rates, was almost twice as great in the Temperate soils as in the Tropical soils. The addition of lime and crop residues tended to decrease water retention capacity of the Virgin Oxisol, whereas the no residue treatment was not affected by lime. Lime did not affect water retention for any crops in the Cultivated Oxisol or in the Mollisol. Time of incubation had a positive effect on soil water-stable aggregation.
