“…There are evidences that the older plantations of Eucalyptus cause a chemical and biological degradation to soils (Bargali et al 1993), what corroborate our results, once the eucalypt soil used in this study comes from an eucalypt plantation over 40 years old and had its physical, chemical and biological characteristics very different from those observed in forest soil.…”

“…An extensive literature deals with the impact of the eucalypt monoculture on soils (Bargali et al 1993), cycling of nutrients (Sankaran 1993;Bernhard-Reversat 1993), inhibition and competition with native vegetation (De Moral & Muller 1970), and also with allelopathic effect on soil microbial activity, as well as on legume tree nodulation (Moura et al 1996). The Brazilian rosewood (Dalbergia nigra) is an endangered legume tree species that occurs in Atlantic Forest and is largely found at Parque Estadual do Rio Doce (PERD) the largest preserved area of ecosystem in Minas Gerais State (MG).…”

Acta bot. bras. 15(3): 305-312. 2001 305 RESUMO -(Decomposição em laboratório de folhas de Dalbergia nigra e de Eucalyptus grandis em terra de mata e de eucaliptal). O objetivo foi acompanhar a decomposição de folhas de D. nigra e de E. grandis em laboratório, enterradas por 12 meses, em solo de Mata Atlântica e de eucaliptal com 40 anos de plantio. Os valores de pH obtidos para os solos de mata e de eucaliptal foram 5,61 e 4,47 e de alumínio 0,32 e 1,89mEqx100, respectivamente. Um grande número de microrganismos (fungos totais, solubilizadores de fosfato e de celulolí-ticos) foram encontrados no solo de mata. Uma perda de massa significativa foi observada após 4 meses de decomposição nas folhas de ambas espécies no solo de mata (30%), enquanto em solo de eucaliptal esta perda foi observada somente após 8 meses (40%). O conteúdo inicial de N e P em folhas de D. nigra é maior do que nas de E. grandis, embora os conteúdos de lignina e celulose sejam semelhantes. A razão C/N é maior nas folhas do eucalipto, indicando que sua degradação deve ser lenta. Apesar disto, não foram observadas diferenças significativas nas taxas de decomposição entre os tratamentos. Ocorreu uma perda significativa de P, lignina e celulose nos tratamentos. Estes resultados mostraram diferenças entre a decomposição de ambas as espécies e a influência do solo de mata e de eucaliptal no processo de decomposição.Palavras-chave -Dalbergia, Eucalyptus, ciclagem, decomposição ABSTRACT -(Laboratory decomposition of Dalbergia nigra and Eucalyptus grandis leaves in forest and eucalypt plantation soils). The objective was to evaluate the decomposition of D. nigra and E. grandis leaves under laboratory conditions when incubated in soils from Atlantic Forest and from a 40-year-old eucalypt plantation for a year. The obtained values of pH in forest and eucalypt plantation soils were 5.61 and 4.47 and for aluminum 0.32 and 1.89mEqx100, respectively. A great number of microorganisms (total fungi, phosphate solubilising and cellulolytic organisms) were found in forest soil. Litterbag study revealed a higher mass loss of the leaves in forest soil in the first four months (c. 30%). In the eucalypt plantation soils loss was observed only after eight months (c. 40%). The initial contents of N and P were greater in D. nigra than in E. grandis leaves, although lignin and cellulose contents were similar. The C/N ratio was higher in E. grandis indicating that its degradation could be slower. Nonetheless, there were no significant differences in the decay rates (k) among the treatments. Phosphorus, lignina and cellulose were lost at the end of the experiment in all treatments. The results show the differences between decomposition of both species and the influence of forest and eucalypt plantation soils in the decomposition process.

“…Being a winter deciduous tree, it produces a substantial quantity of litter fall in the winter season. The litter fall is an important input for replenishment of soil microbial substances and is one of the most imperative pathways for maintaining soil fertility of plantations 13,14 . The poplar tree provides enhanced availability of macro and micro nutrients in the soil by intensification of above-and below-ground organic matter inputs, nutrient cycling, checking soil erosion and fixing nitrogen.…”

“…There was a small decline in C storage in 0-10 cm soil at the grey sand site during the same period. Several studies in the tropics have suggested that decay of eucalypt residues results in smaller contributions to soil organic matter than does turnover of residues from other species (BernhardReversat 1987(BernhardReversat , 1993Wang et al 1991;Bargali et al 1993). The extent to which these conclusions apply to temperate forests is uncertain.…”
