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 ...
Balanço de fósforo em 12 anos e estratégias de culturas anuais para acessar reservas de fósforo construídas ao longo de 15 anos por fontes orgânicas e mineral
(Universidade Federal de Santa MariaBrasilAgronomiaUFSMPrograma de Pós-Graduação em Ciência do SoloCentro de Ciências Rurais, 2022-10-31)
The agricultural production system of Brazil and other countries is highly dependent on
imports of phosphate fertilizers. The quantification and long-term impact of secondary P sources,
such as residues from livestock ...
Posição dos gotejadores e cobertura do solo com plástico, crescimento radicular, produtividade e qualidade do melão
(Universidade Federal de Santa MariaBRAgronomiaUFSMPrograma de Pós-Graduação em Agronomia, 2010-02-26)
Surface drip irrigation is widespread for the melon crop. To improve the efficiency of this system subsurface drip irrigation and plastic mulching can be used. These management practices can influence soil moisture, and ...
Root dynamics and survival in a nutrient-poor and species-rich woodland under a drying climate
(Springer, 2018-03-05)
Background and aims: In Australia’s Mediterranean hyperdiverse vegetation, species that produce cluster roots to mobilise poorly-available nutrients (e.g. Banksia spp.) are an important functional and structural component. ...
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 ...
Dinâmica do sistema radical de uma pastagem do bioma Pampa sob diferentes intervalos de pastejo
(Universidade Federal de Santa MariaBrasilCiências BiológicasUFSMPrograma de Pós-Graduação em AgrobiologiaCentro de Ciências Naturais e Exatas, 2019-12-18)
Currently in Brazil there are six different biomes, being the Pampa biome present only in Rio Grande do Sul. This biome has a very large diversity of grass species and other botanical families of interest. It occupies about ...
