Forest Litter Decomposition as Affected by Eucalyptus Stand Age and Topography in South-Eastern Brazil1

Abstract: -Forest litter decomposition is a major process in returning nutrients to soils and thus promoting wood productivity in the humid tropic. This study aimed to assess decomposition of eucalypt litter in the Rio Doce region, Brazil. Leaf litter was sampled under clonal eucalypt stands aged 2, 4 and 6 years on hillslopes and footslopes. Soil and soil+litter samples were incubated at two levels of soil moisture, temperature and fertilization. C-CO 2 emissions from soil measured during 106 days were higher at 32 °C … Show more

“…The highest values occurred in the WL component in the three studied plots. An average concentration of 487.5 g kg -1 C in Urograndis hybrid litter was found by Skorupa et al (2015). In this study, the mean C concentration in the litter was of 442.4 (± 20.1) g kg -1 in SR2, 443.6 (± 20.4) g kg -1 in R5, and 435.0 (± 21.7) g kg -1 in FR8.…”

“…The maintenance of forest stand production in Brazil has shown importance of maintaining environmental conservation. Some studies have focused on understanding the dynamics of growth Forests 2020, 11, 1097 2 of 18 and export of nutrients, since it is becoming important for the maintenance of soil fertility and to maintaining the productivity of the stands [7][8][9].…”

“…Atualmente, vários estudos têm se concentrado em entender a dinâmica da ciclagem de nutrientes via serapilheira, por sua relevância e elevada influência na manutenção da produtividade vegetal, tanto em plantios, como em florestas naturais de ecossistemas tropicais (Richards et al, 2010;Skorupa et al, 2015). Estudos de processos que regulam as atividades do solo em ecossistemas naturais podem fornecer informações importantes sobre opções de manejo, com a finalidade de manter a fertilidade do solo ao longo do tempo.…”

“…O estoque e a qualidade da serapilheira variam em função do material de origem do solo, da espécie vegetal, do tipo de cobertura florestal, do estágio sucessional da floresta e da época de coleta de amostras para avaliação do teor de nutrientes. Adicionalmente, condições edafoclimáticas, regime hídrico, sítio, capacidade produtiva e tipo de material genético, idade, topografia, sub-bosque, manejo silvicultural, tamanho de copa, bem como taxa de deposição e decomposição, distúrbios naturais como fogo e ataque de insetos, ou artificiais, como também remoção da serapilheira e cultivos sucessivos, influenciam no estoque e na qualidade da serapilheira (Vieira et al, 2009(Vieira et al, , 2013(Vieira et al, , 2014Schumacher et al, 2013;Skorupa et al, 2015;Villa et al, 2016).…”
