Assessment of phosphorus availability in soil cultivated with ruzigrass
(Elsevier B.V., 2018-02-15)
Growing ruzigrass (Urochloa ruziziensis) in crop rotation systems has been suggested as a strategy to increase soil phosphorus (P) cycling and P availability. However, despite increased P lability shown in routine soil ...
Dynamics of phosphorus fractions in soils treated with dairy manure
(2020-01-01)
The evaluation of phosphorus (P) transformations in soil after application of manure or mineral P can improve soil management and optimise P use by plants. The objectives of the present study were to assess organic and ...
Can tropical grasses grown as cover crops improve soil phosphorus availability?
(Wiley-Blackwell, 2018-09-01)
Tropical grasses grown as cover crops can mobilize phosphorus (P) in soil and have been suggested as a tool to increase soil P cycling and bioavailability. The objective of this study was to evaluate the effect of tropical ...

Opportunities for mobilizing recalcitrant phosphorus from agricultural soils: a review
(Springer, 2018-06-01)
Phosphorus (P) fertilizer is usually applied in excess of plant requirement and accumulates in soils due to its strong adsorption, rapid precipitation and immobilisation into unavailable forms including organic moieties. ...
Cultivation affected the level of inorganic phosphorus more than the organic pool of the Pampas soils in Argentina
(Taylor & Francis, 2019-01)
The effects of land use on soil organic and inorganic phosphorus (P) stockswere assessed in the Pampas. Three hundred and eighty-six paired siteswidely distributed over an area of ca. 50 Mha were sampled. Land usetypesincluded ...
A kinetic model of phosphorus metabolism in growing goats
(2000-10-01)
The effect of increasing phosphorus (P) intake on P utilization was investigated in balance experiments using 12 Saanen goats, 4 to 5 mo of age and weighing 20 to 30 kg. The goats were given similar diets with various ...

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 ...
