micronutrient

 [mi″kro-noo´tre-ent]
a dietary element essential only in small quantities, such as selenium, copper, or manganese.

micronutrient

[-no̅o̅′trē·ənt]
any dietary element essential only in minute amounts for the normal physiological processes of the body, including vitamins and minerals or chemical elements such as zinc or iodine. Also called microelement, trace element.

micronutrient

Any of the necessary minor components of a well-balanced diet, including vitamins and minerals, which are ingested either in relatively large amounts (thus known as macrominerals) or in minimal amounts (known as trace minerals).

micronutrient

Clinical nutrition A minor and necessary component of a balanced diet–eg, vitamins, minerals. See Diet. Cf Macronutrient, Minerals, Non-nutritive dietary component, Vitamins.

micronutrient

any TRACE ELEMENT (e.g. zinc) or compound required in only minute amounts by organisms. Compare MACRONUTRIENT.

micronutrient,

n an organic compound such as a vitamin, or a chemical element such as zinc or iodine, that is essential only in small amounts for the normal physiologic processes of the body.

Regional Differences in White Wine Trace-Element Composition
As noted previously, only white wine trace-element concentrations are used here to discuss regional differences in composition.
Many studies suggest that wines can be fingerprinted with trace-element data at the vineyard level through to regional level (Latorre et al.
2) implies that similar geochemical processes are controlling trace-element behaviour in the wines.
An alternative explanation may be that areas with higher Degree Day values--warmer temperatures--yield greater evaporative losses leading to more water uptake by grapes, thus increasing trace-element concentrations in grapes.
