Formas de fósforo no solo após o cultivo de braquiária e tremoço branco
(2013-08-01)
Phosphorus is one of the major factor that limits agricultural productivity in most tropical soils. The objective of this study was to assess P transformations and availability in a soil cropped to brachiaria (Urochloa ...
Biogenic calcium phosphate transformation in soils over millennial time scales
(SPRINGER HEIDELBERG, 2009)
Changes in bioavailability of phosphorus (P) during pedogenesis and ecosystem development have been shown for geogenic calcium phosphate (Ca-P). However, very little is known about long-term changes of biogenic Ca-P in ...

Dynamics of phosphorus fractions in soils treated with dairy manure
(2020-01-01)
The evaluation of phosphorus (P) transformations in soil after application of manure or mineral P can improve soil management and optimise P use by plants. The objectives of the present study were to assess organic and ...
Transferência de fósforo em pequenas bacias hidrográficas com predomínio de sistema plantio direto precário
(Universidade Federal de Santa MariaBRAgronomiaUFSMPrograma de Pós-Graduação em Ciência do Solo, 2014-03-21)
Agricultural activities generate impacts on the environment and require constant study and monitoring to enhance our understanding about the ways and degree of contamination resulting therefrom. The main objective of this ...
Phosphorus transformation in poultry litter and litter-treated Oxisol of Brazil assessed by 31P-NMR and wet chemical fractionation
(Revista Brasileira de Ciência do Solo, 2017)
Phytoplankton-based water quality metrics: Feasibility of their use in a Neotropical shallow lake
(Csiro Publishing, 2018-05)
Urban lakes constitute important recreational areas, but often they are eutrophicated. In this study we discuss the utility of 12 ecological quality metrics to test whether they: (1) can be applied to Neotropical lakes; ...
