Chapter 625 How to judge the soil quality
The purpose of Shang Ruoting doing this was to check whether the soil in this area was the same, and then to check what kind of soil it was.
Although Zhang Xiaohong and Xu Lijie are not novices in agriculture, they have never heard of Shang Ruoting's method.
As they walked, they bent over and picked up a little soil in their hands to examine it.
However, Shang Ruoting's behavior was completely different from the other two. Zhang Xiaohong was a little puzzled when she saw her good sister walking more than ten meters away.
"Ruoting, Teacher Huang asked us to check the soil quality. How are we supposed to judge the soil quality if you just keep walking like this?"
Xu Lijie also looked puzzled.
Shang Ruoting stopped and explained, "I want to feel first whether the soil here is of the same type."
Zhang Xiaohong was even more confused: "Ruoting, could there be different types of soil in the same plot of land?"
Shang Ruoting patiently explained, "We should adapt to local conditions. I also think that we shouldn't be arbitrary in our actions. If the soil quality is different, wouldn't we suffer losses when we farm in the future?"
Zhang Xiaohong nodded, not quite understanding: "Okay then, Xu Lijie and I will experience it with you."
Shang Ruoting didn't say anything else. In her previous life, she had been to the southwest region. The land there was very special. Within one acre of land, there was sand and clay.
Of course, this situation does not exist everywhere. Shang Ruoting also feels that this era is different from later generations after all, so it is better to check carefully.
Xu Lijie also imitated Shang Ruoting and deliberately moved forward step by step.
Soon, she muttered, "Ruoting, we've walked so far, the ground I'm stepping on feels the same."
Shang Ruoting affirmed: "Yes, the places we have stepped on so far are all the same."
As she was speaking, Zhang Xiaohong exclaimed, "Ruoting, I'm here, come here quickly."
Shang Ruoting and Xu Lijie ran to Zhang Xiaohong's side.
Zhang Xiaohong pointed to her area and said, "Ruoting, Xu Lijie, take a good look at this place."
When Shang Ruoting came close to Zhang Xiaohong, she immediately felt something different.
The land here felt soft to the touch, completely different from where they had just walked.
So she squatted down, picked up a little soil and felt it carefully. At the same time, she found a dry branch and inserted it into the soil.
Pulling out the branch, she felt it again.
“This is loam.”
At this time, Xu Lijie and Zhang Xiaohong had also judged the soil quality.
"Ruoting, you are amazing. When we just walked into the experimental field, Xiaohong and I saw only clay. Now the land is really different." Xu Lijie's eyes were full of admiration for Shang Ruoting.
No wonder he became the top scorer in the national college entrance examination and is now the top student in their agronomy department.
Shang Ruoting's thinking and meticulousness are really beyond their reach.
The same goes for Zhang Xiaohong.
"Ruoting, thank goodness you reminded me, otherwise I would have reported to Teacher Huang that this is clay soil."
Shang Ruoting believed that this was due to her rich experience in her previous life, otherwise, she would not have thought of this.
The three continued to walk forward. After walking about two or three hundred meters, the soil changed again. It was clay, the same as when they first entered the experimental field.
Zhang Xiaohong excitedly shouted again: "Ruoting, the soil has become divided again."
"Yes, let's continue observing." Shang Ruoting said with a smile.
Just when everyone else had finished checking and went back to write a note for Teacher Huang, the three of them were still wandering around the experimental field.
Huang Baosen saw that so many classmates had returned, except Shang Ruoting and three others, but he did not seem to be very anxious.
When he first arrived here, he did not meet with his classmates immediately, but went to the experimental field to check the soil first.
As a result, I discovered the uniqueness of this land.
The entire land is made of clay on all sides, while a few acres in the middle are made of loam.
Although this is not the best land for experimental fields, the most important thing is to carry out planting according to local conditions.
Seeing the confident expressions of his classmates, Huang Baosen asked, "How is everyone's observation?"
A male student wearing glasses was the first to answer: "Teacher, I walked around and it's all clay."
Others also reported their findings, and their conclusions were the same as those of the boy with glasses.
Huang Baosen was obviously disappointed to see so many classmates making arbitrary conclusions. However, he did not announce the answer immediately. Instead, he wanted to hear the results of Shang Ruoting and others' research.
About an hour later, just when the students were getting a little impatient, the three people came back from a distance.
Huang Baosen asked in front of all the students: "What are the results of your inspection?"
Xu Lijie spoke first, "Teacher Huang, Ruoting is amazing. She even helped us find two different types of soil."
