Application of Zinc Fertiliser Grade:-

Zinc (Zn) is an essential micronutrient but Zinc deficiency appears to be the most widespread and frequent micronutrient deficiency problem in crops worldwide particularly in countries such as India, China, Pakistan and Turkey where soils are low in available Zn, and cereals are the major source of calorie intake. It is, therefore, highly important to develop cost-effective and quick solutions to the Zn deficiency problem.

Zinc deficiency is common on many soil types including calcareous, heavy clay, alluvial, sandy soils and peats. It is especially common on soils low in organic matter and of high pH. Availability of zinc may be reduced by water logging and where root growth is restricted. Cool wet weather, low light intensity or high soil nitrogen, phosphorus or copper may intensify the deficiency.

Zinc is an essential micronutrient needed not only by people but also by crops. Almost half of the world’s cereal crops are deficient in zinc, leading to poor crop yields. Many agricultural countries around the world are affected by zinc deficiencies. In China, zinc deficiency occurs on around half of the agricultural soils, affecting mainly rice and maize.

In India, zinc-deficient soils occupy almost 50% of the agricultural area and are a critical constraint on yield, but crops are highly responsive to zinc fertilization.

In Turkey, major yield and quality benefits in wheat have been obtained with the widespread use of zinc fertilizers, where half of the cereal growing land is zinc-deficient.

Research has shown that areas with zinc-deficient soils are often regions with widespread zinc deficiency in humans.

A basic knowledge of the dynamics of Zn in soils, understanding of the uptake and transport of Zn in plant systems and characterizing the response of plants to Zn deficiency are essential steps in achieving sustainable solutions to the problem of Zn deficiency in plants and humans (Zinc in soils and crop nutrition), International Fertilizer Industry Association (IFA)and International Zinc Association (IZA).)

Zinc deficiency varies from year to year. Wet, cool, cloudy weather during the early growth season increases  the deficiency. Zinc deficiency in corn is occasionally noted in June, but the deficiency disappears after the  soils dry out and warm up. Crops on poorly drained organic soils show a deficiency probably because of  restricted root growth. Field and vegetable crops often  show differences in response to zinc fertilizer.  Dry edible beans, corn, onions, sorghum, snapbeans, spinach and sweet corn are the most responsive crops.

High soil phosphorus levels have been known to induce zinc deficiency, especially in responsive crops.

For years, the cause of this interaction was  suspected to be the formation of an insoluble zinc phosphate, which reduced the concentration of zinc in the soil solution to deficiency levels. Zinc phosphate has since been shown to be soluble in soil and is an  acceptable source of zinc when finely ground. High levels of phosphorus in plants have been shown to restrict zinc movement within the plant, resulting in accumulation in the roots and deficiency in the tops. Therefore, large applications of phosphorus fertilizer may contribute to  zinc deficiency in zinc-responsive crops.
Application of Zinc - Animal Feed Industry

Zinc oxide is a supplement that constitutes the main source of zinc in animal feed produced for consumption of poultry, cattle, swine, sheep and other livestock. It allows avoiding zinc deficiency, which leads to growth retardation;  skin diseases; a low rate of fertility and more.

Zinc sulphate is also used In the animal feed industry. It serves as a source of zinc, which comprises an essential mineral nutrient.

Manganese Sulphate is used in animal feed industry, as a nutrient and a dietary supplement.

In the field of veterinary medicineto prevent perosis in poultry.

Manganese Oxide is used as a mineral supplement in animal feeds. Manganese Oxide is also used in the pharmaceutical industry in medicines and vitamins.

Ferrous Sulphate, together with other iron compounds, is used to fortify feeds and to treat iron-deficiency anemia.

Application of Zinc -The Rubber Industry

The rubber industry in general, and tire manufacturers in particular, are the largest users of Zinc oxide, owing to its important chemical, physical and optical properties.

Since heat build-up is critical at the higher operating speeds of heavy-duty pneumatic tires (as compared with solid rubber tires) they carry high loadings of Zinc oxide for heat conductivity, as well as for reinforcement. The important role played by Zinc oxide in the rubber industry is expressed in various processes:

Zinc oxide provides a high degree of whiteness and tinting strength for rubber products such as tyre sidewalls, sheeting and surgical gloves, owing to its high brightness, refractive index and optimum particle size.

Application of Zinc - Plastics Industry

Zinc oxide imparts heat resistance and mechanical strength to acrylic composites. It also contributes to the formation and cure of epoxide resin. Adding Zinc oxide to epoxy resins cured with aliphatic polyamines imparts higher tensile strength and water resistance.

Furthermore, Zinc oxide imparts fire resistant properties to nylon fibers and moldings. It is also useful in the preparation of nylon polymers and in increasing their resistance. The formation of polyesters in the presence of Zinc oxide imparts higher viscosity and other improvements. It reacts with unsaturated polyesters to form higher viscosity and a thixotropic body.

It improves the dye ability of polyester fibers. Zinc oxide mixtures stabilize polyethylene against aging and ultraviolet radiation. Zinc oxideincreases the transparency of poly molding resin, and improves the color, tensile strength and vulcanization properties of polyolefins. It also affects the thermal stabilization of PVC, and imparts antistatic, fungi static and emulsion stability properties to vinyl polymers.

Applications in development for Zinc oxide stabilized polypropylene and high density polyethylene include safety helmets, stadium seating, insulation, pallets, bags, fiber and filament, agricultural and recreational equipment.

Zinc Dust provides hardness and low abrasion to the polyester resin molds that are used in the production of plastic parts. Zinc Dust is also used as a filler to increase impact strength, heat distortion temperature and thermal conductivity.
Application of Zinc - Glass and Ceramics Industry

The glass and ceramics industry is also a major user of Zinc oxide in glazes and enamels.

Zinc oxide tends to increase the chemical durability of silicate glass. It is used in phosphate glasses, chemically resistant glass wares, glass metal seals and certain fiber glass compositions. Zinc oxide is also used as a stabilizer for cadmium sulphide and cadmium selenite during heat treatment, allowing the glass to retain its yellow or red color.

Additionally, Zinc oxide is extensively used in enamels. It regulates the expansion coefficient, improves glaze and texture and also enhances opacity and whiteness. Furthermore, it is widely used in porcelain enamel frits, and in glazes for pottery and sanitary ware.

Application of Zinc -Paint and Coating Industry
Zinc oxide is a component in many formulations of durables and protective paints. One of its exceptional features is its opacity to ultraviolet light in the finished coatings, which improves weatherability. The oxide is not discolored by sulphur compounds in the atmosphere, as occurs in some lead pigments. It also protects the paint film from mildew, enhances resistance to abrasion and neutralizes the harmful acids formed by vehicle aging.

Zinc oxide, owing to its amphoteric nature, reacts with organic acids to form soaps that act as a dispersing agent.

Zinc metal powder (zinc dust) and zinc compounds have long been utilized for their anticorrosive properties in metal protective coatings, and presently comprise the basis of metal primers, such as zinc chromate primers.

Zinc dust paints are especially useful as primers for new or weathered galvanized iron. Such surfaces are difficult to protect because their reactivity with organic coatings leads to brittleness and lack of adhesion. Zinc dust paints, however, retain their flexibility and adherence on such surfaces for many years. Furthermore, they provide excellent protection to steel structures under normal atmospheric conditions, as well as to underwater steel surfaces (dams, the interior of fresh water tanks).
