Therefore, an experiment was conducted to quantify the efficacy of foliar fertigation of ascorbic acid (vitamin-C) and zinc (Zn) on the physio-biochemical attributes of barley (Hordeum vulgare L. Genotype B-14011) grown in a saline environment. [unreliable medical source?] For omnivorous adults, more than one-third of dietary zinc can be provided by flesh foods, whereas for vegetarians, plant-based foods are the major dietary source. Ca and Fe contents were increased after the application of Ca at 3% and Fe at 1%. ... Zn is a microelement present in the human body; there is approximately 2-3 g of Zn in a 70-kg live weight human body. Micronutrient elements such as zinc, boron copper, iron, manganese, molybdenum, and chlorine are frequently responsible by the regulatory activity of the cell organelles, being nutrients that are absorbed and found in lower concentrations in plant tissues, they also contribute to supply the nutritional exigency of the plant.

Toxicity occurs when a nutrient is in excess of plant needs and decreases plant growth or quality. Using portable X-ray fluorescence spectrometry, we determined the elemental composition of sandy necrosols from a Corded Ware Culture (ca 2800-2500 BCE) graveyard, Chudeřín, Czech Republic. Zinc (Zn) is often the heavy metal involved. Soils in urban and suburban areas are transformed by human activities, they are characterized by a strong spatial heterogeneity resulting from the various inputs of exogenous materials and the mixing of original soil material, and they often hold pollutants that may be a threat to human health. (1999) found that a sufficient Zn supply could reduce Na accumulation and contributed to salt tolerance in tomato plants. Braz. Among these, salt stress plays a key role in limiting the growth and yield production of economically important agricultural crops. The results showed that the administration of Tagetes erecta efficiently protected albino rats against the lead caused injury, as revealed by some improvement in the enzymatic antioxidant (SOD, CAT and GPx), nonenzymatic antioxidant, Exposure of the source leaf of bean (Phaseolus vulgaris L. cv.

PScript5.dll Version 5.2 /DA (/Helv 0 Tf 0 g ) Our aim is to provide a complete, updated picture in order to orientate future research directions on this topic. the application of zinc oxide (ZnO) NPs in agricultural sciences [15,16]. Comparing the results with our work on the effect of Zn in gills, we conclude that when working in sublethal conditions (15 ppm) Zn toxicity would be bound to organs injury. The estimated world production of zinc is 7.1 million metric tons; the United States produces about 4% of Zinc (Zn) and silicon (Si) have singularly demonstrated the potential to ameliorate Cd toxicity and are important for agricultural production, human health, and environment in general.
