Phosphorous is going to be plant nutrient that will limit the agricultural production in the next millennium. It is a major growth-limiting nutrient, and unlike the case of nitrogen, there is no large atmospheric source that can be made biologically available (Ezawa et al., 2002). As regards the role of P, it stimulate root development and growth, gives plant rapid and vigorous start leading to...

The separation and quantitation of phosphorous oxoanions have been investigated by non-suppressed ion chromatography (IC) with conductometric detection using a modified gluconate-borate buffer as eluent. Hypophosphite being coeluted with the injection peak, its previous oxidation into phosphate is necessary. The method was applied to the determination of hypophosphite and phosphate in several p...

in order to investigate the effects of biological and chemical phosphorous fertilizers and various proportions of maize and grass pea intercropping on yield and yield components of both crops, two experiments were conducted simultaneously in research farm of kerman university and commercial convention farm of bardsir-dashtkar in 2009-2010. the experimental design at two regions was randomized c...

to study the possible use of phytase and yeast (saccharomyces cervisiae) in corn-soy bean meal base diet with different levels of available phosphorous in arbor acers broiler chicks, an experiment was conducted with 264 day old chicks of an average weight of 44.6 grams each. a completely randomized design of 6 treatments and 4 replications (11 chicks per replicate) for periods of starter, growe...

For a long time, the only acceptable treatment for a white phosphorous burn was to keep it covered with water until a physician extracted the phosphorous. When the water dried up or ran-off, contact with air caused the burn to re-ignite. This is a serious problem, especially under battle conditions where water may by scarce or non-existent, and the ability to remove the victim quickly to a trea...

The objective of the present study was to establish an alkali extraction technology for FePO(4)-containing sewage sludge obtained from a wastewater treatment system that includes phosphorous removal by iron electrolysis. By clarifying the extraction properties of phosphorous, organic matter, and inorganic matter, conditions for alkali extraction were optimized. As a result, it was suggested tha...

We thank Metson et al. (1) for their addition to our paper (2). These authors raise an important point, and are definitely right in pointing out the global importance of phosphorous and the dominant role of the livestock industry in its use. Our omission of phosphorous from our calculations, which Metson et al. point out, joins several other important environmental costs of livestock husbandry ...

The experiment was made on a Lohmann Brown classic hybrid from 32 to 42 weeks of age. There were used feeds containing various levels of Ca, P or phytase: NC1 and NC2 were commercial recipes, NC3 was supplemented with Phyzyme (500 TFU/kg), NC4 was supplemented with monosodium phosphate and NC5 with dicalcium phosphate according to nutrient requirements (NRC 1998). There was tested the possibili...
