USES FOR ZINC SULFATE

1. Zinc sulphate is a kind of important abio-chemical material, which has sorts of function in the industrial field.

2. Zinc sulfate is mainly used in the production of man-made fibril concretion, and also used as intermediary dyed reagent in the dying field.

3. It works as fertilizer and animal feed. Zinc Sulphate functions as activator in the medicine industry.

4. Zinc sulfate can be used as feed additive to supply trace element, prevent and cure some diseases because of zinc deficiency and prevent premature death.

5. It also can increase appetite, control blood disorders and bone disease.

How does zinc sulfate dissolved well in water?

ccording to the national standard, the maximum of insoluble matter in zinc sulfate water is 0.05%, however some customers find that zinc sulfate powder cannot be completely soluble in water when testing by oneself, thus begin to doubt the zinc sulfate water-solubility. How does zinc sulfate dissolved well in water?

To make zinc sulfate more completely soluble in water, the tester should control the PH of zinc sulfate solution under 6. Conversely, if solution’s PH value keeps 7.5 or above, zinc sulfate could not well soluble in water. Therefore, to accurately test zinc sulfate water-solubility, one should appropriately add acid content in solution. In acidic solution, high-quality zinc sulfate ‘s water-solubility appears very obviously.

SAFETY

Zinc sulfate powder is an eye irritant. Ingestion of trace amounts is considered safe, and zinc sulfate is added to animal feed as a source of essential zinc, at rates of up to several hundred milligrams per kilogram of feed. Excess ingestion results in acute stomach distress, with nausea and vomiting appearing at 2-8 mg/Kg of body weight.

Rech Chemical Tell You How To Fertilize Potato Economic Effectiveness?

Potato is very favorite healthy food, and it is easy to plant.How To Fertilize Potato Economic Effectiveness? Please check the following aspects.

Topdressing is very important for sweet potato planting, for every 667㎡，apply 20-30 picul of people and livestock manure + 10-15kgs of ammonium bicarbonate  or 5kgs of urea ( 7-8kgs of 40% high effective compound fertilizer is the best) 7-10 days after intertilling; at the same time, 100-150kgs of plant ash + 25-30kgs of calcium superphosphate is needed. When rattan grows long,0.5kg of zinc sulfate with Zn 21.5% or 0.8kgs of compound zinc fertilizer + 50kgs of water is needed to spray, 0.5kgs of manganese sulfate is also ok. In the early October, 100g of monopotassium phosphate, 150g urea +50kgs of water are needed to be sprayed for 2-3 times.

Numerous branches are needed to be pinched. It can increase branches and leaves, so it’s important to control the branch growth.
Drain flooded fields and prevent against water logging.
The best time for harvest is in the mid-November, too early or too late will decrease the output, quality and the storage capacity.
Apply appropriate zinc sulfate or manganese sulfate will supply trace elements for sweet potato timely, and receive good harvest.
