Changes in soil phosphorus in different forest residue management
(INIA Uruguay y Facultad de Agronomía, Universidad de la República, 2012)
We analyze the short term effect of the harvest residues management on the Phosphorus (P) fractions of the soil. Four trials were installed in Northeast Argentina on Vertisols (S1), Mollisols (S2) and Entisols (S3 and S4). ...
Climate-driven changes in sedimentation rate influence phosphorus burial along continental margins of the northwestern Mediterranean
(Elsevier, 2018)
The burial of phosphorus (P) in continental margin sediments is a critical component of the marine reactive P budget, and thus an important factor in marine biological productivity. We determined downcore records of P from ...
Phosphorus fractions in soils of the mangrove, restinga and Atlantic forest ecosystems from Cardoso Island, Brazil
(Csiro Publishing, 2015-01-01)
The availability of phosphorus (P) for the growth of plants often depends on the solubilisation of inorganic phosphates (P fractions) in the soil. The aim of this study was to investigate soil P fractions in terms of ...
Sequential extraction of phosphorus in an Oxisol amended with biosolids in a long-term field experiment in Brazil
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
The continued growth of large cities is producing increasing volumes of urban sewage sludge. Disposing of this waste without damaging the environment requires careful management. The application of large quantities of ...
Fosforo e atividade da fosfatase acida em plantas de feijoeiro.
(Pesquisa Agropecuaria Brasileira, Brasilia, v.33, n.5, p.769-778, maio 1998., 1998)
Phosphorus reduction by sifting fish waste meal
(Universidade Federal de Santa Maria, 2014-10-01)
Fish meal is widely included in animal feed because it contains ideal essential amino acids profile, it is rich in energy, essential fatty acids, vitamins and minerals and with >80% apparent protein digestibility in peneid ...
Can tropical grasses grown as cover crops improve soil phosphorus availability?
(Wiley-Blackwell, 2018-09-01)
Tropical grasses grown as cover crops can mobilize phosphorus (P) in soil and have been suggested as a tool to increase soil P cycling and bioavailability. The objective of this study was to evaluate the effect of tropical ...
