Four dark-red latosols (Haplustox) were sampled at or near the "Centro de Pesquisa Agropecuaria dos Cerrados- CPAC - (Cerrados Agricultural Research Center), in Planaltina, DF, Brazil. A laboratory soil incubation study, at 35C and 0.25 bar water tension, was conducted to evaluate the effect of soil disturbance on N mineralization and to determine the suitability of an incubation procedure for estimating N mineralization in the field. Mineralization rates ranged from ranged 1,2 to 8,8 kg N ha wk over a twelve-week period. The data suggested that as long as is some degree soil aggregation, soil disturbance had no effect on mineralization. The amount of N mineralized during the incubation period in the laboratory showed a low a correlation with the N mineralization in the field. |
