Improvement of phosphorus circulation in the soil is necessary to enhance phosphorus availability to plants. Phosphorus circulation activity is an index of soil's ability to supply soluble phosphorus from organic phosphorus in the soil solution. To understand the relationship among phosphorus circulation activity; bacterial biomass; pH; and Fe, Al, and Ca concentrations (described as mineral co...

Feeding bio-P removal Alkaline fermentation and P-recovery Increasing pH in sludge fermentation increases production of fatty acids needed to feed biological Premoval. Recovery of phosphorus and nitrogen as struvite enables further process optimisation. P-recovery Germany Adapting sludge treatment to optimise struvite recovery Appropriate management of the sludge thickening process can increase...

Phosphorus (P), an essential element required for crop growth has no substitute. The global food security depends on phosphorus availability in soil for crop production. World phosphorus reserves are fast depleting and with an annual increase of 2.3% in phosphorus demand, the current reserves will be exhausted in coming 50-100 years. India and other Western countries are forced to import phosph...

A new model has been developed for assessing the effects of multiple sources of phosphorus on the water quality and aquatic ecology in heterogeneous river systems. The Integrated Catchments model for Phosphorus (INCA-P) is a process-based, mass balance model that simulates the phosphorus dynamics in both the plant/soil system and the stream. The model simulates the spatial variations in phospho...

In the month of June in three distinct blocks Mayurbhanj district, twenty-seven soil samples were collected from nine different rice-growing areas at depths and analyzed. accordance to findings, soils found have low medium levels organic carbon be moderately acidic slightly nature. All under Non-saline condition Electrical Conductivity suitable for crops. The study that pH was main factor influ...

THE presence in bone of an enzy'me capable of hydrolysing organic esters of phosphoric acid to yield inorganic phosphate was demonstrated by Robison [1923]. A considerable body of evidence has since been brought forward by Robison and his co-workers in support of the suggestion that the bone enzyme is intimately concerned in the process of ossification in bone formation. It was suggested that t...

Rabbits and guinea pigs upon certain diets develop an extreme degeneration of the skeletal muscles (15, 22). The onset of these muscle lesions may be delayed or prevented by the inclusion of vegetable oils in the diet (21, 26, 31) or by vitamin E concentrates (23). In dystrophic muscle the creatine content is lower than normal and roughly proportional to the amount of pathological degeneration ...

The phosphoric acid compounds of the blood may be divided into three groups: protein, lipoid, and acid-soluble (1, 2, 3, 4). In the last are included those compounds that are not precipitated with the proteins and lipoids when the blood is treated with the usual acid protein precipitants. In plasma, this acid-soluble phosphorus seems to consist almost entirely of inorganic phosphate (3, 4, 5, 6...

AIM Active vitamin D (1,25-dihydroxyvitamin D₃), PTH, fibroblast growth factor-23 (FGF-23) and Klotho protein are key regulators of phosphate metabolism. Hyperphosphatemia and increased FGF-23 level in patients with end-stage renal disease are associated with increased morbidity and mortality. The relationships among key regulators of phosphate metabolism are still being investigated. FGF-23, t...

In the course of studies on the acid-soluble phosphorus compounds of liver and kidney, it became evident that the fraction comprising the nucleotides represented a complex mixture (1). In an attempt to isolate the individual nucleotides, methods designed to minimize the breakdown of labile phosphorus compounds were employed. The isolation of adenylic acid and of a material representing a mixtur...
