an experiment was conducted to evaluate the effect of replacing dietary limestone with mashhad power plant calcium-waste in combination with available phosphorus level on growth performance, tibial strength and blood alkaline phosphatase activity in broiler chickens. three hundred and eighty four male broiler chickens were used in a complete randomized design experiment with a 4×2 factorial arr...

kochia scoparia is a salt resistant plant that can be used in producing forage in the areas with salt water and soil resources. one of the problems which produce the forage plants in these areas decreases the function and quality of the forage in irrigation condition with salt water. therefore, using the chemical fertilizers can be considered as a useful solution. this study was conducted to ev...

Seventy Two sediments from four stations (Anzali, Tonekabon, Noshahr and Amirabad), located in Caspian Sea-Iranian coast were examined on the basis of P-fractionation in autumn and winter of 2013-2014. Several forms of the phosphorus in sediment were separated and extracted according to sequential extraction method. Then the extracted phosphorus in each fraction was determined by UV–Vis spectro...
