Zinc abundances of planetary nebulae

open access: yes, 2014
Zinc is a useful surrogate element for measuring Fe/H as, unlike iron, it is not depleted in the gas phase media. Zn/H and O/Zn ratios have been derived using the [Zn IV] emission line at 3.625um for a sample of nine Galactic planetary nebulae, seven of ...

Zinc Status in the Soils of Karnataka and Response of Horticultural Crops to Zinc Application : A Meta-analysis

open access: yesJournal of Horticultural Sciences, 2019
Zinc is considered as the fourth important yield limiting nutrient in India, after N, P, and K. From the regular soil analysis data, Indian soils (50%) are found to be deficient in Zn and the zinc deficiency is likely to increase in future.
