nitrogen use efficiency (nue) is usually lower in paddy rice (oryza sativa l.) than in upland crops. for this reason, any attempt to improve nue through the use of different nitrogen (n) carriers, different rice cultivars, properly timed n application, the use of ni-trification and urease inhibitorsis of prime interest. moreover, zinc (zn) next to n seems to be the most important soil factor af...

The experiment was conducted in the lath house of Hawija Horticultural Station/ Horticulture Department/ Ministry Agriculture, during 2021 growing season on one-year-old lemon Transplants. (local species). This study to compare effect some sources iron and zinc their interaction vegetative growth characteristics Tranplants. included two factors: at four levels (control, ferrous sulfate, chelate...

A field experiment was carried out at the research station of College Agriculture, University Anbar, for spring season 2021-2022 to study effect adding organic fertilizer and spraying with zinc sulfate on two cultivars Solanum tuberosum L. The as a factorial within design completely randomized sectors (RCBD); first factor included composting transactions ten Control treatment, chemical fertiliz...

Zinc electrowinning is performed with the application of a current through insoluble electrodes (Pb-Ag), causing the electrolysis of zinc sulfate, with or without impurities, and zinc deposition on the cathode of aluminum. The impurities can reduce the current efficiency and increase the energy consumption in zinc electrolysis. In this work, the effect of nickel and magnesium on zinc electrodep...

A two-stage passive treatment approach was assessed at a bench-scale level using two Colorado Mining Influenced Waters (MIWs). The first-stage was a limestone drain with the purpose of removing iron and aluminum and mitigating the potential effects of mineral acidity. The second stage was a sulfate reducing bioreactor composed solely of 50% corn stover and 50% walnut shells by volume. The prima...

OBJECTIVE To evaluate the therapeutic and prophylactic effectiveness of oral zinc sulfate in recurrent aphthous stomatitis (RAS) in comparison with dapsone. METHODS A double-blind placebo controlled study, conducted in the Department of Dermatology, Baghdad Teaching Hospitals, Baghdad, Iraq between May 2005 and October 2006, in which 45 patients with RAS were recruited and divided into 3 equa...

The influence of chelate and mini-chelate effects on sulfate binding was explored for six amide-, amide/amine-, urea-, and urea/amine-based ligands. Two of the urea-based hosts were selective for SO4(2-) in water-mixed DMSO-d6 systems. Results indicated that the mini-chelate effect provided by a single urea group with two NH binding sites appears to provide enhanced binding over two amide group...

BACKGROUND Zinc is an essential micronutrient used in the form of zinc sulfate in fertilizers in the agriculture production system. Nitrogen-fixing microorganisms are also of considerable value in promoting soil fertility. OBJECTIVES This study aimed to investigate the degree of sensitivity to varying concentrations of zinc, in the form of ZnSO4, in different strains of Azotobacter chroococcu...
