Metabolic change, tillering And root system of brachiaria Brizantha in response to Phosphorus and zinc nutrition
(Journal of Plant Nutrition, London, v. 37, n. 4, p. 509?519, fev. 2014, 2014)
Turbidity and dissolved organic matter as significant predictors of spatio-temporal dynamics of phosphorus in a large river-floodplain system
(John Wiley & Sons Ltd, 2018-09)
Phosphorus (P) inputs are increasing in river‐floodplain systems, but the factors whichinfluence the dynamics of this nutrient are not clear. To assess P dynamics in this kindof river, the main channel of the Middle Paraná ...
Phosphate fertilization and phosphorus forms in an Oxisol under no-till
(Universidade de São Paulo (USP), Escola Superior de Agricultura Luiz de Queiroz (ESALQ), 2010-08-01)
Em semeadura direta o fósforo (P) acumula-se na camada mais superficial do solo, mas os resíduos deixados na superfície liberam P e ácidos orgânicos, que podem melhorar a disponibilidade e a eficiência de fertilizantes ...

Ruzigrass affecting soil-phosphorus availability
(Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA), 2013-12-01)
The objective of this work was to evaluate the effectiveness of ruzigrass (Urochloaruziziensis) in enhancing soil-P availability in areas fertilized with soluble or reactive rock phosphates. The area had been cropped for ...
Dynamics of Phosphorus in sediments of a naturally acidic lake
(Elsevier, 2013-01)
The mechanisms which controls the fixation and/or release of P in sediment of an extremely acidic lake (pH = 2.0 to 3.0) and its response to the influence of eutrophic urban waste water were investigated. The results, in ...
