The status of soil phosphate fractions and the ability of fungi to dissolve hardly soluble phosphates
(Elsevier B.V., 2005-05-01)
Brazilian soils predominantly consist of iron and aluminum oxides and have a low phosphorus content. The present study was carried out in order to assess the status of phosphate fractions in pasture, forest and agricultural ...

Phosphorus fractions as a function of the use of phosphate fertilizers in different soil classesFrações de fósforo em função do uso de fertilizantes fosfatados em distintas classes de solo
(2021-08-05)
Most Brazilian soils have low natural fertility. The main characteristic is phosphorus (P) deficiency and high P adsorption capacity. This creates the need to add phosphate mineral fertilizers, organic or organomineral. ...
In vivo measurements of control coefficients for hexokinase and glucose-6-phosphate dehydrogenase in Xenopus laevis oocytes
(2000)
Hexokinase and glucose-6-phosphate dehydrogenase activities were increased in Xenopus laevis oocytes by microinjection of commercial pure enzymes. The effect of increased fractional activities on glycogen synthesis or on ...
Interaction Study Between Humin and Phosphate: Possible Environmental Remediation for Domestic Wastewater
(2017-01-01)
The increase in demand for food due to the rapid population growth in recent years has raised the use of fertilizers, particularly phosphate salts. This fact has contributed to the excess amount of phosphorus species in ...
Quantitative microscopy characterization of hydrous niobium phosphate into bleached cellulose
(Pergamon-Elsevier B.V. Ltd, 2010-07-01)
In this research the spatial distribution characterization of niobium phosphate into bleached cellulose was carried out combining processing and images analysis obtained by SEM and statistical methodologies. The objective ...
Phosphorus Fractionation in Soil Cultivated with Sugarcane Fertilized by Filter Cake and Phosphate Sources
(2015-10-28)
Studies of phosphorus (P) forms in high-weathering soils, after long periods of phosphate fertilizer application associated with organic residues, are important to optimize P fertilization. This study aims to evaluate the ...
