Effects of Amending Phosphatic Fertilizers with Clinoptilolite Zeolite on Phosphorus Availability and Its Fractionation in an Acid Soil

Applied Sciences, 2020
Soils of the tropics are highly weathered, acidic, and low in phosphorus (P) because of high contents of Al and Fe. Satisfactory P supply is essential to ensure optimum soil and crop productivity.

Temporal Assessment of Phosphorus Speciation in a Model Ramsar Lake System in Asia

Hydrology
This study focused on monitoring phosphorus (P) concentrations in the water of the Ramsar site, Lake Vembanad, with a special focus on the mouths of the river bodies draining into the lake, a known hotspot for eutrophication.

Effects of phosphorus and organic fertilizers on phosphorus fractions in submerged soil [PDF]

Journal of soil science and plant nutrition, 2012
This study was conducted in order to evaluate effects of phosphorous fertilizer (PF)s from sources of triple superphosphate (TSP) and di-ammonium phosphate (DAP) and organic fertilizer (OF)s from sources of cow dung manure (CDM) and munici- pal solid waste compost (MSWC) on phosphorous (P) fractions include aluminium- P (Al-P), iron-P (Fe-P), Reductant

Geochemical Fractionation and Internal Loading of Phosphorus in Urban Lake Sediments in Coimbatore, Tamil Nadu, India [PDF]

Nature Environment and Pollution Technology
Phosphorus (P) is primarily released from sediments through the reduction of iron (Fe³⁺) oxides under anoxic conditions, leading to the dissolution of Fe-bound phosphorus and an increase in dissolved phosphorus in lake water. This study aimed to quantify

Modified Biochar—A Tool for Wastewater Treatment

Energies, 2020
Global deposits of concentrated phosphates, which are a necessary source for the production of phosphate fertilizers, are limited. These reserves keep getting thinner, and every day, large amounts of phosphorus end up in watercourses.

Changes in the Phosphorus in the Plasma Fractions in Avian Erythroblastosis

Poultry Science, 1969
Abstract IN THE terminal phases of avian erythroblastosis (Eb) the plasma α-lipoproteins are altered in a way which produces retardation and splitting of the α-lipoprotein bands on starch gel electrophoresis (Darcel, 1960; Merriman and Darcel, 1964, 1965). These changes may be duplicated by the addition of soaps and turpentines (Darcel et al., 1968),
