Time Travel: After Seizing the Throne, I Lead the Ming Dynasty to Take Off

Hearing this voice, he immediately calmed down, retracted his gaze, and showed an embarrassed expression on his face: It seems... they are really the country bumpkins.

The three captains who led the team were also distracted and out of control.

Even at this moment, he coughed twice to ease the awkwardness, and then, in a pretentious manner, he scolded them: "How can you be so useless! I told you to be quiet! Remember to stay calm and follow the rules from now on!"

Afterwards, the large group of people followed the craftsman who led the way, leaving the area with lingering eyes and reluctance.

The group followed the road and went quite a distance deeper into the Alchemy Department.

Only then did they see a large group of houses appearing ahead. They thought they were finally reaching their real destination. Although everyone restrained themselves from speaking, they still subconsciously stretched their necks out of curiosity to look forward.

Everyone knows.

This is the highlight of the Alchemy Department.

One is the current emperor - the young emperor who is sometimes good and sometimes bad, with mixed reputations; the other is those Taoist masters - either they are cultivating immortality or they can refine elixirs, and they are very mysterious.

No matter which side.

They are all high-end players that ordinary people like them cannot come into contact with on a daily basis.

It is natural to be nervous at this time.

But what surprised everyone again was...

As the crowd approached, they found themselves in a place that was supposed to be solemn, sacred, and majestic...

It seemed as if... there was a faint sound of quarreling???

As everyone continued to move forward with growing curiosity, they gradually began to discern the specific content of the argument.

"Nitrogen fertilizer... I think it's... difficult!"

"It's too difficult! There are multiple conditions involved in making nitrogen fertilizer that we can't achieve."

"First of all, although the air contains a large amount of nitrogen, it is difficult to purify and separate the nitrogen. Secondly, there is hydrogen."

"Hydrogen is a good option! First, remove the impurities from the coal, then react it with water vapor and oxygen at high temperatures to produce synthesis gas containing carbon monoxide and hydrogen. Using copper as a catalyst can further react the carbon monoxide and water vapor."

“The hardest part is not here yet.”

"The catalytic conditions for the reaction of nitrogen and hydrogen to produce ammonia are high temperature and high pressure, and an extremely sealed container is required to provide the reaction environment."

"..."

Everyone heard the sound of quarreling.

They are the core figures of the Alchemy Department today, including Zhang Yuqing, Liu Yuanran, Ma Rui... and other genuine "disciples of the emperor".

Zhang Yuqing and his team had basically finalized the process of batch steelmaking before the New Year. After receiving Zhu Yunhuan's approval, a stable smelting process has gradually been formed within the Alchemy Department.

In the future, these technical experts will not need to worry too much, and their focus will naturally shift to other topics.

And the current topic.

It's fertilizer.

Agricultural productivity is the foundation of everything today.

One way to improve agricultural productivity is to increase crop yields.

The second is to rely on the fertility of the soil, which is related to subsequent development and the increase in the upper limit of production.

Historically, before the 19th century, both Eastern and Western countries could only rely on natural fertilizers such as animal manure and wood ash. It was not until the 19th century that the American chemist Liebig proposed the theory of mineral nutrition: plant growth depends on minerals (such as nitrogen, phosphorus, and potassium).

From then on, the fertilizer industry began to emerge.

The terrifying effects of chemical fertilizers can be illustrated with just one statistic: the emergence and development of chemical fertilizers increased the human population from 1.6 billion to 6 billion in the 20th century!

Now, it’s not long before the new crop of sweet potatoes starts growing.

Wang Yingxin was also sent out to investigate and record agricultural conditions in various places.

In order to meet future needs, Zhu Yunhuan left the research topic of "fertilizer" to the hard-working people in the Alchemy Bureau, and then became a hands-off manager.
