Trace Element Composition of Selected Fertilizers Used in Chile: Phosphorus Fertilizers as a Source of Long-Term Soil Contamination
(TAYLOR & FRANCIS INC, 2009)
Anthropogenic activities like agriculture have resulted in increased concentrations of some trace elements of toxicological and environmental concern in soils. Application of fertilizers has been one of the major inputs ...
Availability of phosphorus in soil and straw in successive tropical grasses crop fertilized with different phosphates
(2016-01-01)
Objective: The aim of this study was to evaluate the availability of P in soil and straw during successive tropical grasses crop fertilized with different phosphates. The crops were grown in 18 dm-3 pots for 50 days. ...
Soil P Diffusion and Availability Modified by Controlled-Release P Fertilizers
(Springer, 2020-11-24)
Slow-release fertilizers have been proposed as tools to increase P fertilizer use efficiency in tropical acidic soils with high P adsorption, low P availability, and mobility. However, results have been controversial since ...
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. ...
Radionuclides, heavy metals and fluorine incidence at Tapira phosphate rocks, Brazil, and their industrial (by) products
(Elsevier B.V., 2006-01-01)
Inorganic phosphate fertilizers may contain radionuclides, heavy metals and fluorine. This paper presents the possible environmental hazards from Tapira phosphate rocks and their (by) products (Brazil) utilized as phosphate ...

Mercury contamination of soil as the result of long-term phosphate fertilizer production
(Bulletin of Environmental Contamination and Toxicology, 2008)
This study was aimed at determining the range and spatial distribution of mercury in a geographical area influenced by the emissions of phosphate fertilizers industries in Rio Grande, Brazil. The case study demonstrated ...
Formas de fósforo no solo sob utilização de estimulador microbiológico
(Universidade Tecnológica Federal do ParanáDois VizinhosBrasilAgronomiaUTFPR, 2017-06-20)
Phosphorus (P) is essential for plants, so the maintenance of their availability in the soil is fundamental, which occurs mainly with soluble mineral fertilization. However, the indiscriminate use of phosphate fertilization ...
Corn fertilization with triple superphosphate in a Typic Hapludox soil under the residual effect of alternative phosphorus sources
(2018-01-01)
In variable-charge soils, the use of alternative phosphorus sources may influence further soluble phosphate fertilization. This study aimed to evaluate phosphorus (P) availability for corn plants in response to triple ...
