Use of pulp mill inorganic wastes as alternative liming materials
Cabral, F.; Ribeiro, H.M.; Hilário, L.; Machado, L.; Vasconcelos, E.A laboratory aerobic incubation study was performed during 18 weeks under controlled conditions to assess the effects of applying different doses of pulp mill inorganic wastes on the physical–chemical properties of an acid Dystric Cambissol. Three different inorganic wastes were tested – wood ash, dregs and grits, and an agriculture limestone was used as reference. Results showed that increasing the dose applie...
Effects of harrowing and fertilisation on understory vegetation and timber prod...
Carneiro, M.; Fabião, António; Martins, M.C.; Fabião, André; Silva, M. Abrantes; Hilário, L.; Lousã, M.; Madeira, M.Harrowing and fertilisation are common practices at middle rotation in Eucalyptus globulus Labill. plantations in Central Portugal. In order to clarify the effects of such practices on understory vegetation and timber production, a field trial was installed in a 5-year-old first rotation eucalyptus plantation, in a region with mixed oceanic and Mediterranean climatic influences. Four treatments that involved ha...

Does harvest residue management influence biomass and nutrient accumulation in ...
Fabião, António; Carneiro, M.; Serrão, V.; Madeira, M.; Balsemão, I.; Hilário, L.The effect of harvest residue management options on biomass and nutrient accumulation in understory vegetation, as well as the contribution of understory to nutrient cycling, were assessed during the early rotation stage of a Eucalyptus globulus Labill. plantation in Central Portugal. The effects of residue management options on early tree growth were also evaluated. Treatments established at the time of planta...
Species richness and biomass of understory vegetation in a Eucalyptus globulus ...
Fabião, António; Carneiro, M.; Martins, M.C.; Cerveira, C.; Santos, C.; Nogueira, C.; Lousã, M.; Hilário, L.; Madeira, M.The aim of this study was to assess the effect of different slash management practices on understory biodiversity and biomass in Eucalyptus globulus coppices in Central Portugal. The experiment consisted of four treatments: (a) removal of slash (R), (b) broadcast over the soil (S), (c) as in S but concentrating woody residues between tree rows (W) and (d) incorporation of slash into soil by harrowing (I). Under...
Fertilidade de solos afectados por práticas de silvicultura intensiva : 2. Efei...
Azevedo, António; Madeira, M.; Hilário, L.; Marques, P.Os efeitos da gestão dos resíduos de abate (folhas, cascas, raminhos e ramos) e da sua composição química nas dinâmicas do P, Ca, Mg e K, foram estudados em plantações de Eucalyptus globulus, instaladas em Arenossolos na região Centro de Portugal. Os tratamentos consistiram na redistribuição dos resíduos de abate na superfície do solo (S) e na sua incorporação por gradagem (I). A mobilidade dos nutrientes foi, ...

Azevedo, António; Madeira, M.; Hilário, L.; Marques, P.Estudou-se o efeito da gestão dos resíduos de abate (folhas, cascas e ramos), nas dinâmicas do C e do N, em plantações adultas de Eucalyptus globulus, estabelecidas em Arenossolos na região Centro de Portugal (39º 15’ N, 8º 59’ W). Os tratamentos consistiram na redistribuição dos resíduos de abate na superfície do solo (S) e na sua incorporação por gradagem (I). O posicionamento dos resíduos no solo influenciou...
