in order to study the effects of silver nano particles, magnetic field in corporation with barium, lithium and micronutrient fertilizers on wheat, an experiment was conducted at research farm of razavi research and technology institute in 2008. experiment carried out with eigth treatments based on randomized complete block design with four replications. treatments were including (t1) magnetic f...

The iron fertilization experiment LOHAFEX was conducted in a cold-core eddy in the Southern Atlantic Ocean during austral summer. Within a few days after fertilization, a phytoplankton bloom developed dominated by nano- and picoplankton groups. Unlike previously reported for other iron fertilization experiments, a diatom bloom was prevented by iron and silicate co-limitation. We used 18S rRNA g...

Fe and Mn (hydr)oxides are widely used as contaminant sorbents in water/wastewater systems but their potential use micronutrient fertilizers is still poorly known. In this research, four nano-metal (amorphous oxide (AMO), Fe-Mn binary (FMBO), two-line ferrihydrite (2L-Fh) goethite) were successfully synthesized completely characterized (infrared Mössbauer spectroscopy, X-ray diffraction particl...

sis usually involve chaotropic agents such as guanidinium chloride and (or) detergents for the dissociation of iron at an acidic pH from transferrin. Reduction is achieved with various reducing compounds such as ascorbic acid, hydroxylamine, thioglycolic acid, and others. Among these, ascorbic acid is unique in its property not only to reduce but also to chelate iron. This property appears to b...

Plant nutrition has a vital role in crop production. This study was performed to investigate the effects of different application methods some nutrients (nano Fe, Zn, and Ti), gibberellin on yield, morphophysiological grain protein white beans 2018 as factorial experiment randomized complete block design with four replications. Experimental factors included seed priming (hydropriming, priming, ...
