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, ...

in order to study the effect of on-farm seed priming and two bio-fertilizers on emergence and yield characteristics of chickpea, a factorial experiment was conducted in a randomized complete block design in hamedan with three replications in 2013. the factors consisted of phosphate fertilizer (0, 50 and 100 percent of recommended) bio-fertilizer (mycorrhizae, barvar2, both of them and no-applic...

This article describes investigations on the phase development (T ≤ 1500℃) of phosphate-bonded Al2O3-MgAl2O4 high-temperature ceramics by a combination solid-state MAS NMR and X-ray diffraction analyses. The ceramic body was bonded with inorganic hydrogen orthophosphates (Al, Mg, Ca, Zr) total binder content 3 wt.% P2O5. binding mechanisms these could be extensively deduced analyses development...

The emergence of biological phosphate esters glycerol could have been a crucial step in the origin and evolution life on early Earth as phosphates today play central role biochemistry. We investigate here formation by employing various rock samples, salts, minerals potential catalysts to aid phosphorylation process. report synthesis including glycerol-1-phosphate, glycerol-2-phosphate, cyclic g...
