yazd asfordi phosphate rock (pr) was partially acidulated at five levels (0, 40, 60, 80, 100%) for increasing the relative agronomic effectiveness (rae) of canola (brassica napus l.), var. rgs in two calcareous and non-calcareous soils. the partially acidulated phosphate rock (papr) was compared vs. the standard fertilizer (triple superphosphate) in two levels (50 and 100 mg p/kg). this study w...

Abstract In this study the wastewater treatment of a gas refinery was investigated by using an aerobic trickle bed filter bioreactor. Using a methanothrophic bacterium was the only difference of this experiment from the common aerobic wastewater treatment processes. In addition to reach the standards of wastewater treatments the other goal of using this special bacterium was the productio...

the high cost of fertilizers in farming systems, soil pollution and degradation of soil are factors that caused to full use of available renewable nutrient sources of plant (organic and biological) with optimal application of fertilizers in order to maintain fertility, structure, biological activity, exchange capacity and water-holding capacity of the water in soil. therefore, in recent years, ...

objective:   intractable epilepsy is a serious neurologic problem with different etiologies. decreased levels of pyridoxal phosphate in central spinal fluid level of patients with intractable epilepsy due to pyridoxine dependency epilepsy were reported. the aim of this study was to compare plasma pyridoxal 5´-phosphate level in patients with intractable and controlled epilepsy. materials   &   ...

in order to study on the effect of nitrogen, vermicompost and nitroxin biofertilizer on growth indices and phenology of sesame a field experiment was carried out at behbahan in summer of 2009. treatments were arranged in a factorial experiment based on rcbd with three replications. three rates of nitrogen fertilizer (50, 75 and 100% of region recommended nitrogen rate,) as a first factor, three...
