The production of potassium nitrate has inspired both the military and agricultural sectors.

The military industry department was happy that they finally had the hope of producing gunpowder by themselves. To be honest, between potassium nitrate and sulfur, sulfur is easy to import, but potassium nitrate is difficult to make. The main reason is that the production of nitrate in Europe is limited, and this limited output is almost all used to make gunpowder. Now with potassium nitrate, the military industry department just sends a ship to Chile or Peru to bring a ship of sulfur back. There are many natural sulfur in this kind of crater in Chile and the Cologne Islands (volcanic islands) in Peru. It is enough to use hundreds of tons at a time to make gunpowder for a long time on the East Coast Navy and the Army.

In addition to the military industry, the agricultural department was also very happy. There is no other reason, because potassium nitrate is also a rare compound fertilizer (which also contains nitrogen and potassium), which has an incalculable effect on plant growth. Therefore, when the northern gunpowder plant first produced nitroso soil, Minister of Agriculture Jinkola was the only senior official at the level of the Central Committee to attend - he was looking at his future fertilizers.

On January 3, 1639, when the technicians and workers of the nitro earth workshop placed the pure white crystals in front of everyone, Jinkola was the first to run up and look carefully.

"Minister Jin, harvest 300 kilograms of pure potassium nitrate per mu of nitrate field." Zhang Zecheng, a former middle school chemistry teacher, said proudly. "The weather will heat up soon, and the nitrate field will enter a rapid production period. You can scrape the nitrate soil once every half a month, and the yield per mu will also increase. In summary, the annual output of these ten mu of nitrate fields is expected to reach 80-90 tons. If you are lucky, you can reach hundreds of tons. This is the power of science."

Behind him were two emigrants from the Ming Dynasty craftsmen who stood respectfully. These two former craftsmen were carrying a purse in their hands, with 300 yuan in cash in the purse. This was the bonus for the top rewarding them for the method of making nucleus soil. To be honest, the method they originally proposed to make nucleus soil is very primitive and crude. If they really wanted to collect nucleus soil according to their method, the efficiency would be scary. Fortunately, some chemistry teachers among the travelers knew the principle of the production of these nucleus soils and the role of nitric acid bacteria in the soil, so they made major improvements to their methods, which greatly improved the yield and speed of potassium nitrate.

"It's less than one hundred tons a year?" Jinkola was a little anxious when she heard this. "How can this be done? One hundred tons of potassium nitrate can make 120 tons of black gunpowder. This output is difficult to maintain the normal training of the navy and army and artillery, right? This won't happen! I need to increase the output! I'm still waiting to pull some potassium nitrate back as fertilizer."

After hearing Jin Kela's words, several officials from the chemistry department looked at each other, and finally Zhang Zecheng asked: "Minister Jin, did you not mention that you should use it as fertilizer when you first made the nitroso? Our factory produces gunpowder and does not produce fertilizer."

"Of course I know." Jinkola waved his hand impatiently and said, "You are not in charge of the country and don't know the price of firewood and rice. The total area of ​​domestic arable land has just reached 31,000 mu, of which Dongfang County has 10,000 mu of wheat, 3,000 mu of potatoes and 6,000 mu of soybeans; Ping'an County has 5,000 mu of rice; Hezhongbao has 5,000 mu of sorghum and 2,000 mu of wheat. According to the grain output last year, if there is no major natural disaster this year, about 7,500 tons of various types of food will be harvested, nearly half of which are potatoes. But do you think how much grain we have to consume every year?"

"How many?" Zhang Zecheng asked stupidly.

"After the new population of thousands, the total population in my country has been historically exceeded 30,000." Jinkola waved his right hand and his voice was inspiring: "Thirty thousand people, based on the two kilograms of grain each day, each person consumes 30 tons of grain a day, which is more than 10,000 tons a year. How big is the food shortage?"

"I'll take a break! Haven't we eliminated the threat of hunger for several years? I remember exporting grain to earn foreign exchange in the past two years." Zhang Zecheng was a little stupid, "How long has it been since we didn't have enough food?"

Hearing the food gap calculated by Jin Kela, Song Qiang, one of the chemical industry leaders who had been standing aside without saying a word, also asked in a question-filled tone: "Minister Jin, why has the food gap suddenly become so big? Hezhongbao and the local area are still using grain to make wine? If there is not enough food, how can people be allowed to use grain to make wine?"

Jinkola's face turned red, and deceiving the two chemical "otaku" did make him feel a little embarrassed. In fact, the East Coast region produces a large amount of fish and shrimp, coupled with the cheap beef imported from La Plata from time to time, as well as the large number of beef cattle, pigs, goats, poultry raised by farmers themselves, and the people of the East Coast do not need to consume two kilograms of grain every day, and the actual food may only be a little more than one kilogram.

However, after all, after being a senior official of the ministry for so many years, Jinkola quickly adjusted his emotions and said with a stern face: "You are really deaf ears and only know how much research is all day long. You don't look at it. How many people have suddenly increased in the country in the past two or three months? More than 2,000 French immigrants, more than 500 pirates, more than 1,000 Ming Dynasty immigrants, more than 800 French children and hundreds of indigenous Indians who have just been included in the country's rule, this is a full 5,000 population! The 5,000 population, which accounts for 20% of the original 25,000 population! There are 5,000 mouths all at once, how much food will be eaten? And now many high-yield areas that originally grow potatoes have been changed to low-yield areas that grow wheat, which further reduces grain output."

"And you also said that brewing wine in China is now a trend." Speaking of this, Jinkola was really a little bit gritted. He himself did not touch the wine, so he hated those who used precious grain to make wine. "Those people are also hateful, and good grain has been ruined by them! Especially in Hezhong Fort, relying on the high mountains and the emperor far away, he made wine with his life, and the good sorghum rice turned into alcohol! It is understandable to say that the demand for this strong wine is strong, but those who made wine purely to satisfy their appetite cannot forgive! I must find a way to suppress this unhealthy trend!"

Two chemical otakus automatically filtered some of Jinkola's words, and then met and calculated bitterly, feeling that according to what Jinkola said, the food for next year is really not enough to eat. No wonder he wanted to make fertilizer.

"Minister Jin, I understand what you mean." Zhang Zecheng nodded and asked, "How much fertilizer does your agricultural department need every year? Let me explain first that there is only potassium nitrate here, nothing else."

"I don't want to do it either. Give me 60 kilograms of potassium nitrate per acre of wheat fields, and supplemented with some struvite. I can increase the current wheat yield per mu to more than 400 kilograms." Jinkolamo said after estimating it.

However, his figure obviously scared the heads of the two chemical groups in front of him.

"60 kilograms per acre?" Zhang Zecheng murmured: "There are 10,000 acres of wheat fields in Dongfang County alone, which requires 600 tons. In addition to the other miscellaneous fields, we have to produce more than 1,000 tons of potassium nitrate a year to be enough for you to squander. More than 1,000 tons, how many nitrate fields do you need to satisfy your appetite? 1,000 acres? Or 2,000 acres? Let me take it!"

"There's no way." Jinkola spread her hands and said helplessly: "We are not many people engaged in agricultural production now. Even if I want to reclaim more land, I can't find enough manpower. Who said that our country's economy is so distorted? Everything is for industrial development, let's see how much our primary industry is squeezed? So, I'm here to find you today. Don't think I'm here to trouble you. The situation is really very serious now. There is only so much arable land, and I have to feed this many people. It's absolutely impossible not to find a way to increase grain yield."

"We can understand you, but the amount of potassium nitrate you need is too large, and we can't make so many." Zhang Zecheng explained, "Nothing else, even if we open a 2,000-acre nitrogen field, where can we find so many human, animal manure, urine and animal corpses? Without these things, it is difficult to make nitrogen. Moreover, if I guess well, a large amount of human, animal manure is needed to be applied to the fields as base fertilizer in agriculture, right? This is a big piece. Now there are less than 3,000 sheep, more than 900 cows, 700 military horses, and more than 500 pigs in China. Oh, by the way, plus a population of 30,000, how much feces are produced every day? How much is consumed?"

"What you said makes sense, but it's better to do it according to the scale of a thousand acres of nitro fields. After I go back, I will report this to the Executive Committee. I will try to get more people and funds to transfer you to you. Just build a large pig farm here, which can produce meat and manure. It's really a killing of two birds. In this way, you can expand the scale of nitro fields as soon as possible and produce more potassium nitrate." Jinkola thought for a while and said, "Also, after a winter, the public toilets in towns and rural household toilets in China should be cleaned. I will organize people to go to these places to pick up manure, concentrate them, part of them for fertilizer for farmland, and part of them for use in the nitro fields here. Wipe them, they are all good things! You have to organize people to pick them up!"

When Zhang Zecheng and Song Qiang saw that Jin Kela had a special liking for feces in public toilets, they felt a chill. This is so much. Others say that people in the chemical department are perverts, but now seeing the obsession of the decent member of Jin Da, Zhang and Song immediately knelt down.

On January 10, just one week after Jinkola left the gunpowder factory, more than 300 Koisan people were sent to Jishu Village, Ping'an Town. With them, they were two ships of stinky feces and a team of construction workers. The feces were transported for use in the nitro fields, while the construction team came to build the nitro fields and pig farms.

Jinkola really fulfilled his promise. It seemed that he was determined to fix fertilizers. Zhang Zecheng shook his head: Do whatever he wants. Anyway, the scale of the nitrate field is too large, and I look so glorious. "What you said makes sense, but it's better to do it according to the scale of a thousand acres of nitrate field. After I go back, I will report this to the Executive Committee. I will try to get more personnel and funds to transfer you to you. Just build a large pig farm here, which can produce meat and manure. It's really a one-off.

Two people. In this way, you can expand the scale of the nitrate field as soon as possible and produce more potassium nitrate." Jinkola said after thinking about it, "Also, after a winter, the public toilets in towns and rural household toilets in the country should be cleaned. I will organize people to go to these places to collect manure and concentrate them, part of them for fertilizer for farmland, and part of them transported to your nitrate fields. Wipe them, they are all good things! You have to organize people to pay them out quickly!"

Others say that people in the chemical department are perverts, but now seeing the obsession of the decent member of Jin Da, Zhang and Song immediately knelt down.
