Phosphorus (P) is one of the most important elements used in fertilizing soils tropical regions due to low efficiency phosphate fertilization. This work aimed fractionate inorganic P (Pi) different mineralogical compositions and relate these fractions with their respective buffer capacity (PBC) indicators. The were characterized physically, chemically mineralogically. Additionally, we evaluated...

The aim of the research was to determine the concentration of total protein and its fractions as well as the concentration of selected mineral components in the blood serum of male broiler chickens Cobb 500 fed diets with different cellulose content. Blood samples were collected for examination from the birds' pterygoid canal veins on their 42 day of age. There was no influence of cellulose pre...

Over the past decade, scientific studies have increasingly concentrated on effects of global phosphorus (P) scarcity food security. A comprehensive strategy that considers demand reduction and recycling possibilities is needed to address P scarcity. Reduced tillage along with crop residue retention could decrease fixation in soil, improve labile content enhance organic-P (Po) buildup its minera...

In this study, the influence of eutrophication on arsenic speciation in lake waters was investigated. Surface water samples (n=1-10) were collected from 18 lakes in Japan during July 2007 and February 2008. The lakes were classified into mesotrophic (7 lakes) and eutrophic (11 lakes) based on the total phosphate (T-P) and chlorophyll-a (Chl-a) concentrations in water column. Inorganic, methylat...

A laboratory incubation experiment was conducted during December, 2017 to March, 2018 in Department of Soil Science and Agricultural Chemistry, College Agriculture, Raichur, Karnataka, India study the fractionation phosphorus (P) black soil amended with different phosphatic fertilizers under submerged condition. The were kept subemerged condition for 90 days phophatic such as single super phosp...

Acid-soluble nucleotides of unifoliate leaves of Pinto bean plants (Phaseolus vulgaris L.) were determined at young, mature, and senescent stages of development. At least 25 components could be distinguished on the basis of inorganic phosphorus determinations and 37 or more fractions on the basis of (32)P labeling, with adenosine di- and triphosphates accounting for 60% of the total moles of nu...

Phosphorus losses by surface runoff from agricultural lands have been of public concern due to increasing P contamination to surface waters. Five representative commercial citrus groves (C1–C5) located in South Florida were studied to evaluate the relationships between P fractions in soils, surface runoff P, and soil phosphatase activity. A modified Hedley P sequential fractionation procedure w...
