Su Xun nodded, then sneered again, shook his head and said: "Why, Your Highness is still insisting on this matter? Haha, I said that urine can never be used as fertilizer. If you continue to insist on this matter, It’s a complete waste of time.”
When Li Ke heard this, he just smiled lightly, raised the car curtain, and said to Su Xun: "Haha, is that so? Now Mr. Su still thinks I'm wasting my time?"
The car curtain was slowly lifted, and Su Xun looked out of the car window.
But just at this glance, everyone was dumbfounded.
"This...what? How is it possible?"
Su Xun stammered, dumbfounded, looking at the scene outside the car window, unable to recover for a long time.
Because at this moment, he suddenly saw that outside the car window was a large green wheat field full of vitality.
Su Xun had never seen such a wheat field in his whole life.
They are so vigorous, strong and full of vitality.
Even with just a glance, Su Xun could easily conclude that the yield of this wheat field must be 30% higher than that of ordinary wheat fields.
Then Su Xun hurriedly got out of the car and began to feel the impact of the wheat field on him up close.
Stroking the green wheat seedlings with her palms, Su Xun was so excited that she almost trembled all over.
He really couldn't believe that such a large wheat field was located in Kunyang, a bitter cold place in the north of the Great Wall.
After all, even the best fields in the south of the Yangtze River, which is like spring all year round, are just like this.
Suddenly, Su Xun seemed to have thought of something, and he quickly turned around and ran towards Li Ke who was beside him.
"Your Highness, I want to know how you did it?" Then there was a look of surprise on his face, and he said in surprise, "Is it because you used that urine fertilizer?"
However, after saying this, Su Xun shook his head again and again, and muttered: "No, it's impossible. Urine cannot be used as fertilizer. This has been a consensus for thousands of years..."
His expression became complicated again, and he murmured to himself: "But how can we explain this?"
Seeing Su Xun's expression, Li Ke couldn't help but shake his head and smile, and said softly: "That's right, Mr. Su, the reason why this wheat field is growing so well is actually because it uses the fertilizer I made with urine."
"In the past few days, I have asked people to apply urine fertilizer to the fields every day, but within four or five days, the growth of this wheat field has already exceeded that of nearby wheat fields."
Li Ke said with a smile: "Actually, I didn't know how effective this fertilizer was at the beginning, but now its effect is still obvious to all, so I decided to promote the use of this fertilizer on a large scale."
Hearing this, Su Xun's face suddenly changed, and he said very firmly: "That's natural. Such good fertilizer must be promoted and used. I believe it won't be long before my wheat fields in Kunyang are as prosperous as this one."
As he spoke, Su Xun had a look of longing on his face.
But as soon as he finished speaking, Li Ke's sigh came from the side.
"No!" Li Ke shook his head and said, "Mr. Su, you still think of the problem too simply. To be honest, I have calculated before that even if the entire city of Kunyang is used, the final fertilizer obtained will be It’s only enough to sustain the application of hundreds of acres of fields, so we still have to find other ways to get more fertilizer.”
Su Xun nodded with some disappointment, then suddenly thought of something, and said: "By the way, didn't you, Your Highness, pile up so much manure in the threshing floor in the east of the city? Couldn't that be used as well?"
Li Ke nodded, but immediately shook his head and said: "The manure can indeed be used, but the quantity is still too small. I have made rough calculations before. The manure plus urine fertilizer can only sustain less than 2,000 acres at most." The use of farmland, but if we include the 5,000 acres of cultivated land in the west of the city that will be reclaimed in the future, it is still far from enough."
Li Ke's words instantly seemed to pour cold water on Su Xun. He murmured: "Yes, what should we do?"
While Su Xun was deep in thought, Li Ke suddenly seemed to have thought of something and asked Su Xun excitedly: "Mr. Su, are there any large coal fields around Kunyang City?"
