Hydrologic regulation of plant rooting depth
(National Academy of Sciences, 2017-10-03)
Plant rooting depth affects ecosystem resilience to environmental stress such as drought. Deep roots connect deep soil/groundwater to the atmosphere, thus influencing the hydrologic cycle and climate. Deep roots enhance ...
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 ...
Root distribution of 'Valencia' orange under traveler gun irrigation
(Empresa Brasil Pesq AgropecBrasiliaBrasil, 2007)
Variation in biomass allocation and root functional parameters in response to fire history in Brazilian savannas
(2021-01-01)
Fire is a fundamental ecological factor in savannas because it affects vegetation dynamics and ecosystem functioning. However, the effects of fire on below-ground compartments, including biomass and root traits, and their ...
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 ...
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 ...
Dry matter production of shoots and root density of two cultivars of Lablab purpureus (L.) Sweet
(Fundação Estudos Agrarios Luiz Queiroz (fealq), 2001-01-01)
This experiment was conducted in green house conditions to evaluate the DM accumulation in the shoots and in the roots of two cultivars of Lablab purpureus (L.) Sweet. A 2x3 factorial (two cultivars and three evaluation ...

(Fundação Estudos Agrarios Luiz Queiroz (fealq), 2001-01-01)
This experiment was conducted in green house conditions to evaluate the DM accumulation in the shoots and in the roots of two cultivars of Lablab purpureus (L.) Sweet. A 2x3 factorial (two cultivars and three evaluation ...
Estimations of rooting depths and sources of plant-available water (PAW) in flatland petrocalcic soils under different land uses
(Elsevier, 2020-03)
Plant-available water (PAW) is one of the most important issues in productive landscapes around the world. Besides climatic conditions, it depends on several factors, among them, land uses, the rooting and water table ...
