Chapter 73: The Harvest Before Winter
"3 tons of struvite… According to the average use of 15 kilograms per 666 square metres, the actual cultivated land area is definitely more than 66600 square metres, which is much larger than I expected."
On the way back, Chu Guang spoke his thoughts out loud while writing in his notebook with a pen.
"It seems that my speculation is correct. They should have applied some soilless cultivation techniques, and this part of the production capacity accounted for 15% to 30% of the total production capacity... or even more."
Brown Farm would make some manure itself and buy a little from other merchants. The actual cultivated area was probably larger than Chu Guang thought.
Before coming to this world, Chu Guang heard of a pipe-type soilless cultivation technique that could maximize the use of space and water resources. As long as the fertility was sufficient, the actual production could be ten times more than that of the usual land cultivation.
In the pre-war era of this world, there seemed to be a similar technology, and the use of space had been maximized. There were "skyscrapers" that integrated automatic seeding, cultivation, ripening, harvesting, assembly line transportation, and packaging and distribution being developed regardless of energy costs. Those facilities could really achieve more than tens of thousands of kilograms per 666 square meters.
It was called the computer numerical control (CNC) farming tower, which was regarded as the ultimate body of industrial farming technology.
Very cyberpunk.
Brown Farm’s energy was certainly not that luxurious, but since part of the electricity could be used for food, their electricity resources should not be in short supply.
In addition, they had been farming for at least a century, so they should've inherited a part of the technology and improved it to adapt to the wasteland environment.
At this moment, Chu Guang suddenly had an idea.
"Could it be… that they’ve planted some kind of energy crop?"
Brown Farm did not only grow green wheat. It was said that this stuff would ripen very quickly. After the harvest, there would be a chance to plant a round of shofar potatoes, beans, fruits and vegetables or other crops.
Perhaps the latter was the one that needed more fertility?
At the end of the 20th century, some people had used cash crops, by-products, or artificially cultivated special crops to produce ethanol and biodiesel. With the gradual maturity of this technology, these crops were sometimes specifically classified as "energy crops" depending on their uses.
Logically speaking, in the pre-war world that had mastered controllable fusion technology, similar technologies may be more advanced than he imagined.
However, in the era of major breakthroughs in nuclear fusion technology, the actual use of this energy crop should not be for the production of fossil fuel substitutes.
It was used as an industrial raw material.
"... Brown Farm itself did not have industrial capacity. Some of the cash crops it produces are used as fuel and partly sold to merchants from Boulder City to supply Boulder City's factories as industrial raw materials."
"The product is probably some kind of rubber, crude oil analogues or other hydrocarbons."
"Moreover, the consumption of fertility by this crop should not be small!"
Chu Guang wrote this line in his notes.
The gain from this transaction was greater than he had imagined.
Not only did they acquire the grains and tools in the wagon and the "order" for 3 tons of struvite in the spring of next year, but also the intelligence collected indirectly through transactions.
Especially since this information was impossible to collect when he was a scavenger.
After he went back, he could publish the background information on the official website for the players' reference.
While Chu Guang was analyzing the information, the players next to him were also whispering quietly.
"One kilogram of struvite can be exchanged for 10 kilograms of grain? I'm not mistaken, am I."
"You are wrong, it is 12 kilograms."
"I don't understand, is this green wheat too cheap, or are the stones we picked from the lake too valuable?"
"Maybe both? Maybe not... Wait, for how much do we buy the food from the warehouse?"
"It seems like 1 kilogram of green wheat costs 1 silver coin. I know what you want to say. 1 kilogram of struvite can only be exchanged for 2 copper coins, right?"
"Yes! Is this reasonable?"
