For a long time, mineral requirements of goats have been extrapolated from those of cattle and sheep. To date advances in goat nutritional research allow more specific mineral recommendations. Endogenous losses of calcium and phosphorus might be more related to dry matter intake than to the bodyweight. True absorption coefficient of P is probably higher for goats (70–75%) than for other ruminan...

Agricultural drainage water continues to impact watersheds and their receiving water bodies. One approach to mitigate this problem is to use surrounding natural wetlands. Our objectives were to determine the effect of iron (Fe)-rich groundwater on phosphorus (P) removal and nutrient absorption by the utilization of the iron plaque on the root surface of Glyceria spiculosa (Fr. Schmidt.) Rosh. T...

from the last few years, the inclusion of microbial phytase in poultry diets has increased significantly, mainly in response to heightened concerns over phosphorus pollution of the environment and as cheaper means to make phosphorus available to birds from phytate. phytate is the major form of phosphorus, abundantly found in cereal grains, beans and oilseed meals used in poultry diet but the mo...

introduction cultivated sunflower is one of the largest oilseed crops in the world. sunflower seed is the third largest source of vegetable oil worldwide, following soybean and canola. nitrogen is one of the most important elements for crops to achieve optimum yields and quality. phosphorus (p), next to nitrogen, is often the most limiting nutrient for crop and forage production. phosphorus ava...

December 2 of this year became a memorable day in human history when NASA held a press conference to declare an epoch-making finding. Felisa Wolfe-Simon, a NASA astrobiologist at the US Geological Survey, led a team investigating a bacterium that can sustain its growth by replacing phosphorus with arsenic, an element generally harmful to living organisms. Her report was published online in the ...

Sulphate assimilation provides reduced sulphur for the synthesis of cysteine, methionine, and numerous other essential metabolites and secondary compounds. The key step in the pathway is the reduction of activated sulphate, adenosine 5'-phosphosulphate (APS), to sulphite catalysed by APS reductase (APR). In the present study, [(35)S]sulphur flux from external sulphate into glutathione (GSH) and...

Chiral ferrocene derivatives belong to privileged ligand classes for asymmetric transition metal catalysed reactions. Hetero-bidentate phosphane ligands are hybrid ligands, which combine the properties of phosphorus with those of other donor atoms. This feature creates further asymmetry around the metal centre, which may be helpful for increasing the stereoinduction. Therefore, hetero-bidentate...
