Consequences of mixing Acacia mangium and Eucalyptus grandis trees on soil exploration by fine-roots down to a depth of 17 m
(Springer, 2018-03-01)
Fine-root functioning is a major driver of plant growth and strongly influences the global carbon cycle. While fine-root over-yielding has been shown in the upper soil layers of mixed-species forests relative to monospecific ...
Fine root isotropy in Eucalyptus grandis plantations. Towards the prediction of root length densities from root counts on trench walls
(Springer, 2010-09-01)
The objectives of the study were to assess changes in fine root anisotropy and specific root lengths throughout the development of Eucalyptus grandis ( W. Hill ex Maiden) plantations and to establish a predictive model of ...
Dynamics of soil exploration by fine roots down to a depth of 10 m throughout the entire rotation in Eucalyptus grandis plantations
(Frontiers Research Foundation, 2013-07-09)
Although highly weathered soils cover considerable areas in tropical regions, little is known about exploration by roots in deep soil layers. Intensively managed Eucalyptus plantations are simple forest ecosystems that can ...
Contrasting phenology of Eucalyptus grandis fine roots in upper and very deep soil layers in Brazil
(2017-12-01)
Background and aims: While the role of deep roots in major ecosystem services has been shown for tropical forests, there have been few direct measurements of fine root dynamics at depths of more than 2 m. The factors ...
Root and shoot interactions in a tropical integrated crop–livestock–forest system
(2020-05-01)
Integrated crop–livestock–forest systems (ICLFS) have potential advantages compared to monoculture, but most studies quantifying plant biomass in integrated production systems, have quantified only the aboveground component ...
Deep rooting of rainfed and irrigated orange trees in Brazil
(Springer, 2017-02-01)
Fine roots of orange trees reached a depth of approx. 6 m in a sandy tropical soil. Root area index was more responsive to irrigation than leaf area index. Although the crucial role of deep rooting on the hydraulic functioning ...
A fast exploration of very deep soil layers by Eucalyptus seedlings and clones in Brazil
(Elsevier B.V., 2016-04-15)
Although pioneer studies showed several decades ago that deep rooting is common in tropical forests, direct measurements of fine root distributions over the entire soil profile explored by the roots are still scarce. Our ...
Below-ground biomass and productivity of a grazed site and a neighbouring ungrazed exclosure in a grassland in central Argentina
(Wiley Blackwell Publishing, Inc, 2004-04)
We estimated the below-ground net plant productivity (BNPP) of different biomass components in an intensively and continuously 45-ha grazed site and in a neighbouring exclosure ungrazed for 16 years for a natural mountain ...
Consequences of clear-cutting and drought on fine root dynamics down to 17 m in coppice-managed eucalypt plantations
(2019-08-01)
Improving our understanding of the spatiotemporal dynamics of fine roots in deep soil layers is of utter importance to manage tropical planted forests in a context of climate change. Our study aimed to assess the effect ...
Fertilization increases the functional specialization of fine roots in deep soil layers for young Eucalyptus grandis trees
(2018-01-01)
Functional specialization of fine roots was found for Eucalyptus grandis trees at harvesting age (6 years) on tropical soils. Aiming to elucidate whether functional specialization is a ubiquitous feature of eucalypts, we ...
