Tamm Review: Deep fine roots in forest ecosystems: Why dig deeper?
(2020-06-15)
While the number of studies dealing with fine root dynamics in deep soils layers (depth > 1 m) has increased sharply recently, the phenology, the morphology, the anatomy and the role of deep fine roots are still poorly ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
Influences of edaphoclimatic conditions on deep rooting and soil water availability in Brazilian Eucalyptus plantations
(2020-01-01)
Brazilian roundwood industry is one of the most important and productive in the world, with Eucalyptus plantations alone representing 73% of the total planted forests. Deep rooting in these plantations represents a more ...
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 ...
Importance of deep water uptake in tropical eucalypt forest
(Wiley-Blackwell, 2017-02-01)
1. Climate models predict that the frequency, intensity and duration of drought events will increase in tropical regions. Although water withdrawal from deep soil layers is generally considered to be an efficient adaptation ...
