How to do foliar fertilization well?

Zinc sulfate, manganese sulfate monohydrate, copper sulphate pentahydrate and other microelements fertilizers produced by Rech Chemical all belongs to efficient water soluble fertilizer, which are widely used as a foliar fertilizer. The effects of foliar fertilizer not only associated with fertilizer sorts, but also do with the fertilization methods.

1. Foliar fertilizers species should be selected with some targets. When basic fertilizer is full enough, trace elements can be applied in foliar fertilization.

2. Suitable acidity. Generally, PH 5 ~ 8 is required.

3. The concentration of foliar fertilizer should be considered based on the type of crops
4. Foliar fertilizer with better solubility.

5. Foliar fertilizer should be used as soon as possible and not kept for too long.

6. It’s better sprayed and strengthened in the critical period of crop growth. For example, gramineous crops such as wheat, rice, their root absorbing ability abate in late growth period, foliar fertilization can supply nutrition and increase grain number and grain weight.

In total, trace-elements as zinc sulfate, manganese sulfate, such foliar fertilizers are widely applied by farmers for quickly absorb ability and high efficiency.
 

Magnesium Sulfate Ore on Mars.

Do you know there’s magnesium sulfate ore on Mars?

Today, news from Baidu occasionally comes to my eyes that Opportunity discover bright bands of minerals on the Mars’s surface. The introduction in this news involves the magnesium sulfate.

Because my company engages in sulfate industry and produce magnesium sulfate, as long as I  catch the familiar things with my products, I want to know everything clearly .So I read the article carefully one more time . Through reading, I have known that minerals on the Mars discovered by Opportunity may be gypsum. However gypsum is formed by the function of water when settled. This discovery proved that water historically exists in rock fracture of surface of Mars. The opportunity also found that the bedrock ground contains magnesium sulfate and ferric sulfate mineral calcium composition. These substances formation also need the participation of water.

Now, you know, magnesium sulfate ore not only exist on the earth but also on Mars.

Summing up the usages of two main sulfate products

In order to let our customers have a clear understanding for the usages of zinc sulfate and ferrous sulfate, today we sum up the usages as follows for your reference:

Zinc sulfate: Zincs sulfate can be widely used as feed additive, agricultural fertilizer and mineral processing materials. Zinc sulfate can be divided as powder and granule from the appearance, and zinc sulfate also can be divided as zinc sulfate monohydrate and zinc sulfate heptahydrate from molecular formula.

Generally speaking, zinc sulfate monohydrate powder is used as feed additive, and granule is used as fertilizer for the character of slow release. However, I have to point out that if you purchase zinc sulfate for agricultural use by foliar spraying, then zinc sulfate powder is better than the granule.

Absolutely, zinc sulfate can also be used as dying industry and electroplating industry.

Ferrous sulfate: Just like zinc sulfate, ferrous sulfate also can be used as feed additive, agricultural fertilizer and dying agent. Besides that, ferrous sulfate plays an important role in waste water treatment industry and in cement industry. 

Controlling Ferrous Ions In Ferrous Solution Is Very Important To Coating

While coating, do well control the amount of ferrous ion in solution. If few ferrous ions in solution , add ferrous sulfate to supple the vacancy. If ferrous appear insufficient, the brightness of coating will be bad; if ferrous content keeps more than l. 5 g/l, the coating surface will take black.

When too few ferrous ion in solution, usually add ferrous sulfate to make up. Because ferrous ion can make the micro leveling effect in zn-based alloying. Sufficient ferrous ion in zinc ferrous nickel lighting solution will help to update the coating’s brightness. General content is 0.6 ~ 0.8 g/L.

The right amount of ferrous sulfate is 0.05 ~ 0.1 g/L per 16 hours. And it should be chemical pure grade because industrial grade is not pure enough and often contains copper ion or nitrate radical ion.


The methods of ferrous sulfate adding :
Dissolve it it in hot water and complex with sodium potassium tartrate tetrahydrate .Then it’s ready to be add in. Remember the amount of sodium potassium tartrate tetrahydrate is 4 ~ 5 times of ferrous sulfate.
