Can buying industrial potassium chloride from a soil fertilizer formula store be used as a corn-based fertilizer? Let's take a look.

First of all, let's be clear: industrial-grade potassium chloride can also be used as corn fertilizer.

In order to solve the problem of whether industrial potassium chloride can be used as a base fertilizer for corn, we should first clarify two small questions: first, whether corn is suitable for potassium chloride? Second, the difference between industrial potassium chloride and agricultural potassium chloride? After understanding these two small questions, I think it is not difficult to answer the above questions. Next, let's explain it for you.

Is corn suitable for potassium chloride?

The reason for clarifying this problem is that even the potassium chloride fertilizer used in agriculture can not be used as potash fertilizer in corn agricultural production if there is no chlorine in corn. So let's get this straight first. The issue of chlorine taboo has been discussed many times in previous articles. We have seen chlorine-avoiding crops such as sweet potatoes, watermelons, potatoes and grapes, such as tubers or fruit crops with high sugar content, but corn does not avoid chlorine. There have been many related research experiments in agricultural production.

What is the difference between industrial potassium chloride and agricultural potassium chloride?

With regard to industrial potassium chloride, its purity is basically more than 98%, which can be said to be very pure. It is mainly used in industry for the production of potassium hydroxide, potassium carbonate, potassium nitrate, potassium sulfate, potassium chlorate, potassium dihydrogen phosphate, potassium permanganate and so on. It is even used as potassium tablets in medicine to supplement potassium deficiency in the human body.

However, it is very different for potassium chloride used in agriculture, because the use of potassium chloride in agricultural production is to apply potassium chloride into the soil or foliage, which is far less stringent in terms of purity than industrial requirements. You can take a look at the purity mark on the agricultural potassium chloride bag. Generally, the imported chemical fertilizer bag is marked as (potassium oxide in agricultural fertilizer means potassium content > = 60%), which translates into potassium chloride content > = 98.8%. However, this is only imported potash fertilizer, and like the general domestic potash fertilizer, the potassium oxide content is more than 57%, and this purity is even lower. It's not nearly as pure as industrial grade.

From the above analysis, it is not difficult to see that industrial potassium chloride is only higher in purity and higher level of purification than agricultural potassium chloride. However, industrial-grade potassium chloride is far from needed in agricultural production, at least in terms of input and output. Industrial-grade potassium chloride is too expensive, and the purity of analytical pure potassium chloride used in our laboratory is 99.99%. This price is even higher, and if such potassium chloride is used in agricultural production, I am afraid farmers will lose money.
