Tian Ertong really wanted to talk to the old rich man, but Bai Haitang told him that if you are like this without any evidence, people will not admit it, but will go to the county magistrate to bite. If the old rich man gives some money to the county magistrate, it may be difficult for you to go to jail.

After hearing this powerful relationship, Tian Ertong gave up.

He promised that after the fight, he would look at the ground well and not leave a single step.

Bai Haitang came to the cave and deal with the water. What should I do? It has been integrated into the ground and cannot be drained. This will only strengthen nutrition and improve the plant's disease resistance.

Bai Haitang immediately thought of pure nitrogen and potassium sulfate. Only by integrating these two things into the ground can the plant's disease resistance be improved, and perhaps there is still some help.

This old rich man, Bai Haitang wants you to taste the power of modern chemistry, make you busy and let you know that you have messed up with the wrong person!

Bai Haitang found the crystals of potassium sulfate in the cave, which were colorless and transparent, and broke with a light touch, and then blended into the water, thus forming potassium fertilizer. Compound farm fertilizer had been added to the ground before, so there was no need to worry about the acidity of potassium fertilizer to destroy the soil.

It is a bit difficult to extract pure nitrogen.

Although the air contains a lot of nitrogen, it is necessary to pressurize and reduce the temperature to liquefy the air and evaporate the liquefied air. The liquid nitrogen is used to lower the boiling point than the liquid oxygen. Therefore, liquid nitrogen can first become a gas and separate it from the air.

But now, in the wild and backward pastoral countryside, there are no tools, and these are simply fantasy.

Nitrogen fertilizer can only be extracted from other aspects.

Bai Haitang thought about it, urea, ammonium water, ammonium salt, ammonium chloride, ammonium nitrate, and ammonium sulfate were mixed in a certain proportion and all became nitrogen fertilizers for agriculture!

And these materials can be found almost all in this mine!

The moment of my eyes suddenly became clear.

Bai Haitang had already prepared nitrogen and potassium fertilizers in one day. He sprinkled these into the ground in Hotan Ertong and sprinkled the acre of winter plum house.

"Sister-in-law, is this okay?" Tian Er didn't know what his sister-in-law got after a day of business, so that she could save the crops?

"I'll know in a few days." Bai Haitang was not 100% sure.

Tian Er and Tian Niu, as well as mother-in-law, took turns to guard against outsiders to make trouble again.

As the crops returned to their previous growth day by day, they were even more unable to guess Bai Haitang. They didn't know what method she used, and at the same time they also had a little more respect for her.

I don’t know where this wife is running all day long, but she always brings unexpected things.

A few days later, the crops in the field returned to their original growth.

Bai Haitang has not been idle these days. Old rich man, your unlucky day is coming, and it depends on how you rent it this year.

Bai Haitang found yellow natural sulfur in the mine cave.

Heat it carefully to obtain sulfur trioxide and sulfur dioxide, and then melt them into water, thus forming simple sulfuric acid...

Now, it is time to turn the raid. Bai Haitang diluted the sulfuric acid. Taking advantage of the darkness of the night and high winds, he quietly came to the unguarded old rich man's field and sprinkled the dilute sulfuric acid on the roots of the plant...

After a busy night, the next morning, Bai Haitang found that she couldn't straighten her waist. She turned out to be quite tired of doing bad things.

The next day, I looked around and saw that the old rich man’s land was withered and yellow. This scene was what once appeared in the white crabapple field.
