Phosphorus in Antarctic surface marine sediments - chemical speciation in Admiralty Bay
(Oxford, 2013-06-11)
This study describes the relation of the phosphorus chemical speciation in surface sediments with input processes in Admiralty Bay, King George Island, Antarctica. The sediments were analysed with a sequential extraction ...
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. ...
