| Abstract | Patterns of N release from the prunings of two tree species (Inga edulis and Centrosema macrocarpum) and one herbaceous legume (Colubrina glandulosa) in relation to Investigate Were the chemical Characteristics of the materials. Also, the soil N distribution in slash and burn WAS Following documented. Lignin + polyphenols to nitrogen ratio (L + PF: N) WAS better than coal to nitrogen ratio (C: N) as a predictor of the quantity of N release. In contrast to the exponential decay Assumptions of models, Were retarded mineralization rates in most cases. Slash and burn disturbance resulting in a mineral N flush in the first meter of soil; Some of This N leached below WAS one meter. |
