The control on zinc sulfate’s heavy metal content get further improved

Since July, southern of China has entered severe summer, and in the same months of the previous years, continuous heat weather usually directly affects the zinc sulfate factories ‘production. To some small -scale factories, they has to stop the production in the heated summer. There’s no exception this year too. As to Rech Chemical Co. Ltd, we still normally keep balance in production and sales. 

Better yet, on July 2, we received a sampling inspection report from a governmental third party testing center, which reports the important test indicators such as zinc sulfate's heavy metals content  lead, arsenic, cadmium content is 0.50 PPM, 0.01 PPM, 0.55 PPM, which not only much lower than national standard (national standard for lead, arsenic, cadmium: 10 PPM, 5 PPM, 10 PPM), but also improved forward much compared with our previous internal control indicators. 

Rech Chemical Co. Ltd’s product could show excellent quality in the test results, due to our severe purchasing standards on raw materials and constant seeking for technology improvement. The original test report on zinc sulfate’s heavy metals content released as follows:

What kinds of crops are zinc-like crops?

Many consultants call or email to Rech Chemical Co. Ltd: "Could I apply zinc fertilizer in rice or wheat or something else? How to use zinc fertilizer?"  Now Rech Chemical Co. Ltd explain to you what kinds of crops are zinc-like crops? What crops particularly need zinc fertilizer?

Zinc is one of such most important trace elements in vegetable and crops’ growth and development. Actually, zinc content in the soil is too less to meet the crop’ general needs in growth period. Extral zinc is commonly added by fertilization. It needs zinc supplementation especially in alkaline soil, like as north of China where soil PH is higher and effectiveness of the zinc reduces. Meantime, lots of crops have especial preference on some nutrients, but what kinds of crops are zinc-like crops? What crops particularly need zinc fertilizer?

Zinc-like crops: maize, rice, cotton, sorghum, Chinese cabbage, eggplant, beans, tomatoes, herbs, fruit, watermelon, flax, citrus, apple, peach, and leguminous vegetables and crops are zinc-like crops and most sensitive crops to zinc. Medium sensitive to zinc crops are such as potatoes, Onions, sugar beet and so on.

If you are the one who are growing zinc-like crops above, apply moderate amount of zinc fertilizer on them. Zinc fertilizer can not only increase yield and improve quality, but also may some help to prevention and treatment of viral diseases if scientifically use zinc fertilizer.
