this research carried out in the rafsanjan pistachio orchard to investigate the effect of n form, manure, k and fe on yield, nut quality and leaf mineral nutrients concentrations of pistacia vera l. cv. fandoghi grafted on badami-riz zarand rootstock. the experiment was as factorial with four factors including; manure (without manure and 10 kg tree-1 sheep manure), n form (ammonium sulfate and ...

Fog composition and deposition fluxes of fog water and fog solutes were measured in six radiation fog events in San Joaquin Valley, California during winter 1998/1999. Measurements made at 2 hr intervals with 0.30 m2 and 0.06 m2 Teflon deposition plates yielded excellent reproducibility (relative standard deviations of 3.8–6.0%) for water, nitrate, sulfate and ammonium. Water fluxes measured at...

Ammonium Nitrate (AN) prilling Process is nonlinear and non stationary in nature. Due to uncertainty created by nonlinear conditions like temperature rise due to exothermic reaction in the neutraliser, level in the evaporator, velocity of the cooling air in prilling tower, temperature and moisture content of prills and size of the prills. Due to these difficulties the degree of automation is qu...

In the crystal structure of the title salt, C7H12N2 (2+)·2NO3 (-), the nitrate ions are located in the vicinity of the protonated amine groups, accepting strong N-H⋯O hydrogen bonds. Each ammonium group is involved in a total of three such inter-actions with neighbouring nitrate ions, generating a three-dimensional network. In addition, there are π-π inter-actions between the aromatic rings of ...

to study the effect of nitrogen form and ph of nutrient solution on the uptake and concentration of fe, zn, cu and mn in roots and shoots of spinach plant, a factorial experiment was conducted with two factors including nutrient solution ph in three levels (4.5, 6.5 and 8.0) and nitrate to ammonium ratio of nutrient solution in five levels (100:0, 75:25, 50:50, 25:75 and 0:100). the experiment ...

A series of 2-arylquinazolines have been synthesized in moderate to excellent yields by one-pot tandem reaction of (2-aminophenyl)methanols, aldehydes and ceric ammonium nitrate (CAN). The utility of this transformation was demonstrated by its compatibility with a wide range of functional groups. Thus, the method represents a simple and practical procedure to access 2-arylquinazolines.

A carbon-Ferrier rearrangement on glycals has been performed by using ceric ammonium nitrate to obtain products in moderate to good yields with high selectivity. The versatility of this method has been demonstrated by applying it to differently protected glycals and by employing several nucleophiles. The obtained C-allyl glycoside has been utilized for the synthesis of a orthogonally protected ...

one of the important methods of plant propagation in large scale so as genetic manipulation and artificial seed production is somatic embryogenesis technique. the obtained results from this methods related to different factors including condition of culture medium. therefore, the aim of this study conduction were determining the role of molybdenum during carrot petiole somatic embryogenesis. at...

The estuarine nitrogen cycle can be substantially altered due to anthropogenic activities resulting in increased amounts of inorganic nitrogen (mainly nitrate). In the past, denitrification was considered to be the main ecosystem process removing reactive nitrogen from the estuarine ecosystem. However, recent reports on the contribution of dissimilatory nitrate reduction to ammonium (DNRA) to n...
