If a large amount of labor had been hired for the large-scale production of ammonia, the collective farms would have paid a huge price before the high grain yields brought about by the fertilisers. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Yang Mingzhi asked himself, that level of China is also the state to concentrate its efforts to build a large number of fertilizer factories, once such factories exist in a certain city, environmental pollution will follow, causing residents to complain. With the large output of chemical fertilizers, grain production has increased on a large scale. At the same time, such factories also feed a large number of workers because of the large demand for labor.

In order to produce one ton of ammonia, dozens of tons of logs are consumed in the whole process, and even if waste is controlled, the huge wood loss will make Ran worry.

Yang Mingzhi closed his eyes and thought about the technical difficulties mentioned by Ivanov.

Equipment problems are not a problem at the moment, the biggest problem is the raw materials.

"If we put a lot of charcoal into ammonia, our black powder production will be hindered," he asked. Therefore, we have to expand charcoal firing, and we have to build some more supporting factories. ”

"In addition to the consumption of charcoal, the consumption of nitric acid has also increased. We lack saltpeter here, and we only rely on human and animal manure to make nitrate to further produce nitrate, which is now almost at the limit. ”

Yang Mingzhi was stunned, "Could it be that 30,000 people and pee every day is not enough for those nitrifying bacteria to be busy?" ”

It was interesting to say this, and Ivanov's tense face cracked. "The chief is right, we produce gunpowder, picric acid and hydrazine nitrate, and we need more raw materials to produce more. Now that we have a plan to mass produce chemical fertilizer, we need a lot of charcoal, a lot of nitrate, but we don't lack sulfur. ”

"Oh? Why we are not short of sulfur. ”

"Because there's a sulphur mine in this swamp! There are also hot springs there! As he spoke, Ivanov pointed in the direction of the target.

Yang Mingzhi suddenly remembered at this time that there was a hot spring in the swamp! It was an underground hot eye, surrounded by a lot of sulfur.

The Eighth Route Army, which was fighting a fierce battle with devils on this plane, had no choice but to find a way by themselves because the Chongqing authorities did not pay the Eighth Route and there was no ammunition supply.

The most produced is naturally hand grenades, but these "border made" have a huge disadvantage, that is, the explosion power is not large enough. Why? Lack of sulfuric acid! Why is there a lack of sulfuric acid? Because of the lack of sulfur.

Because of the geographical convenience, God has given the swamp a hot eye, and with a sufficient supply of sulfur, the black powder produced is even more powerful.

Ivanov continued: "If the governor especially wants a high yield of potatoes, we make ammonia, urea, which are nitrogen fertilizers. Due to the local soil characteristics, I am afraid that a variety of fertilizers are needed, such as potash. If we make potassium sulfate, we can also make potatoes more productive. ”

"Potassium sulfate? Potassium fertilizer? Yang Mingzhi never thought of this, he has always simply believed that as long as synthetic ammonia is made, grain production will be increasing. Where does potash come from?

Ivanov smiled: "Naturally, it is plant ash, and the residue after burning is simply mixed into the soil to be potash." But since we have sulfur, it's perfectly possible to make more efficient potassium sulfate. In order to obtain these materials, we should indeed look at the habitats of migratory birds. ”

This man's remarks reminded Yang Mingzhi that the Pripet Marsh is very huge, and many times the winters here are not unbearable, and the climate is relatively warm and humid. This winter's rare cold snap caused temperatures to drop below -10 degrees Celsius, which has never been seen here before.

A large number of migratory birds spend the winter, and the fish in the wetlands provide them with a lot of food, leaving droppings behind, and the warm summer is also a habitat for a large number of birds, and eventually there are many areas of guano in the swamp.

Ivanov put forward the idea of using guano!

"The climate here is usually humid, and the environment doesn't allow guano to turn into struvite stone, but there is a lot of nitrate and potassium in the densely packed soil of guano. Finding them to further mass-produce nitrate will allow us to expand our weapons production capacity. We can even use the special soil there to change the soil structure directly on our current arable land, so that food production will increase. ”

The biggest problem of peat soils is the lack of nutrients, and the production teams of the collective farms are now ploughing the ground in the first place of work in the process of clearing new farmland, adding the ashes of burning manure and charcoal to the muddy new world, and then sowing the potato tubers. Even so, the soil is still starved of nutrients, and the increase in potato yield will not be significant.

"Even if we pull all the soil back from the habitat of migratory birds, it would be more efficient to spread fertilizer directly." Yang Mingzhi said.

The creation of a fertilizer plant is a must, the project has already been decided, and everyone, including the Novgomel City Committee, knows about it and supports it. Belarus has a large number of forests, among which the tall Korean pine is abundant, and its wood is hard and dense, and the charcoal produced is of very high quality.

The economic level of Belarus has been so low that most of the region is underdeveloped, and a large number of Korean pines up to 50 meters tall with trunks of one meter in diameter abound. Yang Mingzhi summed it up, so the weight of such a tree must be dozens of tons. If you simply calculate an account, if you produce one ton of ammonia, you only need to consume one tree to complete it, and the damage to the environment is not so tragic.

As for the bird droppings and hot spring sulfur mentioned by Ivanov, these can be exploited, but the first thing to solve is the problem of synthetic ammonia.

This closed-door meeting between the two men lasted until late at night, not so much about the establishment of a fertilizer plant, but as a discussion between the "two chemists" on a series of issues.

From fertilizers, weapons materials, and even agriculture, it has become a topic of discussion. Finding a soulmate in this remote swamp was undoubtedly a gift to Ivanov, an old pedant.

No matter how many difficulties there are, a fertilizer plant has to be built. Because in view of the current state of arable land in Novgomel, the demand for chemical fertilizers is only 100 tons, and the future demand for chemical fertilizers is not huge, mixed with organic and inorganic traditional fertilizers such as plant ash and human and animal manure.

The population base here is only 30,000, even if one person has to eat one kilogram of potatoes a day, 60,000 catties a day is enough, and the actual demand is less than this. Even according to the minimum yield of 2,000 catties per mu of potatoes, Novgomel can eat 30 mu of yield a day, and at least 1,800 mu is needed to maintain this productivity.

When it comes to calculating economic accounts, Yerenkina is an expert. She has at hand information on the current state of cultivated land and the average grain yield per mu in Novgomel.

Yang Mingzhi knows that in fact, the villagers' development of the land has been going on in the past few months, coupled with the current large-scale production campaign and military reclamation, the grain output of the horse grain harvest season in April will increase a lot year-on-year, and by June, the output will explode.

In Yang Mingzhi's understanding, the yield of potatoes per mu was four or five thousand catties, which could be achieved in the Qing Dynasty, and later the farmers of New China used special fertilizers on a large scale, coupled with the perfect potato detoxification process, and the yield of one ton per mu was normal.

In fact, Maozi has long regarded potatoes as a staple food, and their potato varieties are excellent. However, the barren peat soil of the marshland is unusable, and the grain production is really terrible.
