Influence of the addition of phosphogypsum on some properties of ceramic tiles
(2018-06-30)
Phosphogypsum (PG) is a waste from phosphoric acid production, and this work evaluates the use of PG as an additive in ceramic manufacturing. Ceramic samples were produced by adding different concentrations of PG (5, 7.5, ...
Dolomite and phosphogypsum surface application effects on annual crops nutrition and yield
(Amer Soc Agronomy, 2008-03-01)
Brazil has extensive area with acid soils. Using phosphogypsum and soil acidity tolerant cultivars are alternatives to crop establishment in no-till system without previous limestone incorporation in many agricultural soils ...

Long-term effects of lime and phosphogypsum application on tropical no-till soybean-oat-sorghum rotation and soil chemical properties
(2016-03-01)
Root growth, nutrition and crop yield can be affected by soil chemical modifications caused by superficial limestone and phosphogypsum application in a no-till system. Using this approach, this study was conducted in ...
Sequential Chemical Extraction for a Phosphogypsum Environmental Impact Evaluation.
(AIP Publishing LLCNew York, 2013-05-06)
Phosphogypsum (PG) is gypsum generated during phosphoric acid production. PG is stocked in large stacks or accumulated in lakes; it contains heavy metals and naturally occurring radioactive elements. The metal contamination ...
Long-term effects of lime and phosphogypsum on soil carbon and nitrogen and physical attributes under tropical no-till
(2021-03-01)
Lime and phosphogypsum applications are well-established practices in weathered soils, and their surface application under no-till (NT) can affect soil physical attributes and C and N fractions. This study determined the ...
