BACKGROUND Phytic acid is a strong inhibitor of iron absorption from fortified foods. In adults, this inhibitory effect can be overcome by adding ascorbic acid with the iron fortificant or by using a "protected" iron compound such as NaFeEDTA. In addition, the use of NaFeEDTA as an iron fortificant has been reported to increase zinc absorption in adult women. No information is available on iron...

Objective:  In addition to the role of organic matter in plant nutrition, this material improves soil quality, physical structure, ventilation and water supply, and ease of penetration and expansion is rooted deep in the soil surface. Effects of organic matter due to climatic factors, soil characteristics may vary from region to region, resulting in organic materials management must be given to...

Abstract Sulfate-containing wastewater has a serious threat to the environment and human health. Microbial technology great potential for treatment of sulfate-containing wastewater. It was found that nano-photocatalysts could be used as extracellular electron donors promote growth metabolic activity non-photosynthetic microorganisms. However, also induce oxidative stress damage cells. Therefore...

drought stress is the most limiting factor of agricultural production through the world. to evaluate the effect of super absorbent and humic acid to reduce drought stress in sugar beet production, a strip split plot arrangement based on randomized complete block design with three replications was conducted at research field of faculty agriculture, ferdowsi university of mashhad, iran during gro...

organic compounds including seaweed extract were applied in organic production system and sustainable agriculture. one of these compounds is humic acid that was used widely in research and commercial programs. humic acid is an organic acid obtained from humus and other natural resources with hormonal effects and improving nutrient absorption, increasing root and shoot biomass. in order to inves...

Background: There are several causes leading to male infertility, like oxidative stress, and nutritional deficiency of trace elements i.e., selenium and zinc. The Zinc is the following only to iron as the most abundant element in the body. Although, Zinc is found in red meat, white meat, fish, and milk; the World Health Organization (WHO) approximates that one-third of world population is defic...

Zinc sulfate is an inorganic compound: the sulfate salt of zinc and a good source of zinc ions. The molecular 40 formula for zinc sulfate is ZnSO4. A graphic representation of the structure of zinc sulfate is shown in figure 1 41 (Pubchem, 2014). Zinc sulfate appears geologically as a white crumbly salt efflorescence known as “goslarite.” 42 Goslarite, the heptahydrate of zinc sulfate was first...
