Abstract: We investigated the chemical and biochemical composition, residue decomposition, and mineralization rate of leguminous (Cajanus cajan, Crotalaria spectabilis, and Lablab purpureus) and spontaneous vegetation in two experimental coffee systems in south- east Brazil. The nitrogen (N) content of the shoot biomass varied from 19.3 to 45.7 g kg?1 , and phosphorus (P) content ranged from 1.6 to 3.8 g kg?1 . C. cajan contained the greatest values of N and P, whereas spontaneous plants had the lowest values. In both areas, spontaneous vegetation had the greatest values of carbon (C) / P, C/N, polyphenol/N, and (lignin + polyphenol) / N ratios. Decomposition rate increased in the order C. cajan < C. spectabilis < L. purpureus < spontaneous vegetation. There was no correlation between the chemical and biochemical composition and the decom- position rate under field conditions. However, the cumulative carbon dioxide (C-CO2 ) produced by the residues under laboratory conditions was correlated positively with initial contents of N and P and negatively with polyphenol/N and (lignin + polyphe- nol) / N ratio (P < 0.01) throughout the sampling period. The low nutrient content, especially for N, of spontaneous vegetation is compensated by the greater decomposi- tion rate under natural conditions than that of introduced species. Management of the spontaneous plants is therefore an attractive alternative for sustainable agriculture. |
