"Luxury? How can it be extravagant, isn't it just some fertilizer? Yang Yuanzhao said casually, in his opinion, the use of chemical fertilizer as the base fertilizer, for the planting and production of crops, has a great role in promoting, which in later generations, is already common sense that everyone knows, so in Baotou also implemented this, before cotton, is because of the use of a large number of chemical fertilizers, which has obtained huge economic benefits.

John smiled bitterly and asked, "But, Mr. Yang, do you know how much it takes to invest 6 million acres of land to use chemical fertilizers?" ”

The input of chemical fertilizer, just John knew that the 20 acres of land at Yale University back then, just the investment of chemical fertilizer, was more than 1,000 US dollars, you know, 20 acres of land, even if all the yields, the benefits will not exceed 15 US dollars per mu, 50 US dollars at once, so that Yale University in addition to a small batch of practical research, can not be promoted at all, it is completely more than worth the loss, but from the Pacific island countries guano, An acre of land is invested at a maximum of 0.25 US dollars, which has a huge market in the United States, and many ocean-going cargo ships, along the Pacific Ocean, used to pull guano.

The United States can pull guano, but China can't, the Pacific Ocean is too far away from China, just the transportation cost, it will be as high as a certain distance, plus China's poverty, guano 0.25 US dollars, in exchange for silver ocean, that is, five jiao, such an investment, there is no labor insurance willingness.

"Yes, Mr. Yang, according to the average value of 45 kilograms of urea per mu, at least 45 US dollars, 6 million mu, even if it is large-scale production, if it is halved, this investment will be as high as 150 million US dollars, this is definitely an astronomical amount, you are sure Baotou can get it!"

"How big can it be, $1 per acre, the total investment is only more than 6 million, which is no problem at all!"

"What an acre of land, a dollar, how can fertilizer be so cheap!"

"How could it not, I imported it for 50 kilograms for a dollar!" Yang Yuanzhao smiled slightly, in this era, the dollar is still quite valuable, and the thing directly linked to gold, the dollar dollar, is here

"Yes, how can urea be so cheap, I remember that more than 40 kilograms of fertilizer were applied to an acre of land, as if when I left, the price of fertilizer was one dollar per kilogram."

"That's how cheap I bought it anyway." Yang Yuanzhao was stunned for a moment, after he got urea from Shanghai, he directly used urea as the basic product, with the help of the all-in-one machine production, the previous more than 20,000 acres, almost 1 million kilograms of urea, calculated, that is, 1,000 tons, which is in the all-in-one machine upgrade today, that is, a period of output, but now, more than 6 million mu, or according to 50 kilograms, is close to 300 million kilograms, that is, more than 300,000 tons, this number is too huge, his all-in-one machine day and night, It also takes a long time to be able to produce, this problem seems to be ignored, it seems that the synthetic ammonia project must speed up the progress, at least to ensure the production of fertilizer in Baotou.

In John's heart, it seems to be overturning the river and the sea, the chemical fertilizer is synthesized with natural saltpeter, because of the important proportion of saltpeter in arms and explosives, the price of natural saltpeter is quite expensive, is it possible that someone has mastered a more advanced synthesis method and does not use natural saltpeter?

The same doubts flashed in everyone's hearts, but Yang Yuanzhao kept silent after that, thinking of the global recruitment of German and American workers, 2,000 people were recruited to China at once, and the large buildings under construction in Baotou, it can be seen that the investment is very large, and the amount of work is quite high, perhaps, in China, there are really a lot of secrets.

A few miles, it was soon gone, Xiao Han had already come over and reported the situation to Yang Yue, and Yang Yue was also at the door early.

To be honest, the first time they saw this agricultural research institute, John and the others were first disappointed, after all, the large steel frame, 15 meters high, covering an area of tens of thousands of square meters, and the ordinary three-story building in front of them, formed a huge contrast.

Although this three-story small building is also made of cement and has a steel skeleton, there is a comparison, and the gap is too big, and it doesn't look like it's very advanced.

"Kate!" Seeing Yang Yue come out, John also said excitedly, as a former friend, he had a lot to say. Other people don't have much contact with Yang Yue, but in a foreign country, in a completely unfamiliar place, when they see their former classmates, the feeling in their hearts is very different, and everyone asks each other, mainly about their own development. Most of the development that can come to China is not so smooth, especially John, although he is engaged in related industries, but he is gradually distancing himself from the research of agriculture itself.

"I'll take you, go to see the place of work, the door is not the place to chat, simply take everyone to see the dormitory, 5 people, even if it is a plus person, the three-story building is also completely lived, now, with the support of Yang Yuanzhao, the real yàn district has begun a major transformation, the establishment of a real glass greenhouse, plastic greenhouse, as a temporary equipment, in the previous Baotou insufficient preparation situation, it can be regarded as a successful role, but the real research, what is needed is the constant temperature control.

Now Baotou's power is very tight, but after the arrival of Truss, this power tension will get a huge change, as long as the 6000 horsepower steam engine, the transformation into a generator is successful, electricity will no longer be a bottleneck, but become a new source of power, in this case, Yang Yuanzhao also began to consider air conditioning, fans, and modern machines, in the application of real greenhouses, constant temperature or precise temperature control, is the key to an agricultural real room, glass greenhouse in a certain degree dù, It is even possible to control the concentration of carbon dioxide, which is the key to high agricultural yields.

Now, the construction of the glass thermostat has begun, and the reserved air conditioning space has also been completed, just waiting for the electricity to be in place.

Yang Yuanzhao first took everyone to visit, it is this glass greenhouse, so tall, this is everyone's first impression, the greenhouse, a full 5 meters high, all are huge glass structures, it looks like a beautiful crystal palace.

"This is the future main research institute, a total of 13 acres, including three 7 small and 10 different glass greenhouses, and 10 different agricultural products can be planted at the same time, but it has not yet been completed, we can do a simple study over there." The direction that Yang Yuanzhao pointed to, there is a little smaller, about half an acre of glass greenhouse, which is specially designed for Yang Yue, not only has perfect control, but also has air conditioning, Yang Yuanzhao's home air conditioner, also got to this era, in the past, this is just a small air conditioner of 2 horses, but in this era, it is the most cutting-edge

Entering this real room, there are agricultural research equipment that they are all familiar with, of course, there are some things they don't particularly understand.

"What is this?" John looked at a machine he didn't recognize, it seemed that Yang Yue had worked here before, and there were still things on it that had not been cleaned up.

"This is my current research project, this is to study the effect of acid and alkali on plants, as well as the absorption efficiency of fertilizers, etc., so far some results have been produced, the absorption rate of urea has increased by 15, if the use of foliar top dressing, the use of urea efficiency will be improved!"

The efficiency of urea, this is the research that Yale University has been doing, the effect of urea is too good, as a fertilizer, he almost has the advantages of being difficult to replace, but hovering in front of him, it is a very real problem, his value is raised, on the one hand, it is necessary to study how to reduce his cost of the method, on the other hand, is to study the way to strengthen its effect, reduce the number of urea per mu, this fixed process dù above, reduce the overall input cost.

John's very clear is that urea was first discovered by the Germans, and then the technology spread to the United States, and now the most popular fertilizer in the whole United States, of course, is only limited to the research of the agricultural college, and this fertilizer will greatly increase the yield of plants, but the cost is too high.

John from the hands of Yang Yue, took over the real yàn record, the earliest record was half a year ago, at that time, Yang Yue had begun to study urea, but only recorded some numbers jù, to two months later, with most of the numbers jù out, Yang Yuanzhao began to go deeper, he tried at least 17 different fertilization methods, and finally the results included root fertilization and foliar fertilization, all of which were topdressing with different proportions of urea solution, and the effect was OK, it can be seen, Yang Yue's research has made a breakthrough, even above Yale.

John was silent all of a sudden, back then, when he was in school, his grades were not inferior to Yang Yue, and even in some aspects, he was still above Yang Yue, when he heard that Yang Yue had returned to China, he was worried that Yang Yue would sink, after all, the Qing Kingdom in his eyes at that time did not have scientific soil at all, maybe after this year, when he saw Yang Yue again, Yang Yue had become an authentic landlord.

But fate is changeable, Yang Yue, who returned to China, can do what he likes and conduct agricultural research, but in the United States, he has to use his professional knowledge to cooperate with his agricultural machinery to deceive consumers in order to make a living.

Although the others didn't speak, they were more or less thinking the same way in their hearts, trying their best to understand the results that Yang Yue had achieved, and then continuing to study, they were all high-achieving students who graduated from Yale, no one was much worse than others, there was no reason why Yang Yue did it, they couldn't do it.
