60s: I have a store

Chapter 440 Carbon Nitrogen Ratio

Zhou Yimin brought expert Wang to the experimental field prepared in advance. For convenience, he also built a simple house in advance to store some things.

When he arrived at the field that Zhou Yimin was going to use for the experiment, Expert Wang saw that although the land was not large, it was very flat. There was also some fertilizer made from fermented chicken manure piled around it. Zhou Yimin had spent a lot of time and effort to get this from the old branch secretary.

"Expert Wang, this is the land we plan to use for the experiment." Zhou Yimin pointed at the field, his eyes full of anticipation.

Expert Wang walked around the field, carefully checked the condition of the soil, picked up the fertilizer beside him and smelled it, and had a preliminary understanding of Zhou Yimin's preparations.

“The preparations have been pretty solid.”

Expert Wang commented, “However, many details need to be considered in order for the experiment to be successful.”

The old branch secretary came with a few people, wanting to see if there was anything he could help with. He couldn't just let other experts do the digging themselves!
"Expert Wang, do you think there is anything else that needs to be improved?" Zhou Yimin asked?
Expert Wang replied: “Not yet.”

Zhou Yimin quickly took out his notebook and pointed out the parts he didn't understand to expert Wang one by one, like pouring beans.

Afterwards, expert Wang, Zhou Yimin and the old party secretary came to an open space in the village, which was temporarily used as a place for discussion.

Zhou Yimin, the old branch secretary and Zhou Zhiming were all amazed. It seemed that this expert Wang was really good.

Unlike in later generations, many experts are just eating shit and talking nonsense, which is completely useless. I really can't understand how they can become experts.

Therefore, in later generations, "expert" became a derogatory term.

The old Party Secretary suddenly asked, "Expert Wang, what do you think of my fermented chicken manure fertilizer?"

Although Zhou Yimin told him how to do it, he basically led the villagers to complete it, and he wanted to know if there was any room for improvement.

Expert Wang did not refuse: "If you want to know, take me to the place where you ferment?"

Since the fermented fertilizer is not far from here, it can be reached in a few minutes on foot.

Everyone came to the place where chicken manure fertilizer was stored. Expert Wang bent down, carefully observed the color and texture of the chicken manure, and even got close to smell it.

Then he picked up a shovel and turned over the chicken manure to check the inside.

After an inspection, Wang straightened up and said seriously: "Old Party Secretary, your chicken manure fermentation has a certain effect. It has been initially decomposed and there is no obvious pungent odor, which shows that the fermentation process is basically correct.

However, there are still many areas for improvement. First, the fermentation time can be extended a little bit, so that the fertilizer can be decomposed more thoroughly and the nutrients can be released more fully.

Secondly, during the fermentation process, you can add some materials such as straw and sawdust to adjust the carbon-nitrogen ratio and make the fermentation more uniform.

In addition, you can see that the humidity in this pile of chicken manure is not uniform. Some places are too wet, which will affect the activity of microorganisms.

It is important to control the humidity, keeping it at around 50% to 60% is more appropriate.”

The old branch secretary was a little confused. He didn't expect that there were still so many things that had not been done.

"Expert Wang, what did you just say about carbon?"

Expert Wang spoke a little too fast, so the old branch secretary didn't hear it clearly.

Zhou Yimin explained: "Old Party Secretary, it's the carbon-nitrogen ratio."

Expert Wang nodded and said, "Yimin, you are right. As for the carbon-nitrogen ratio, we can add straw at a ratio of thirty to one." "As for humidity, you can grab a handful of chicken manure with your hand and squeeze it tightly. There will be water stains between your fingers but no water will drip. When you release it, the chicken manure will clump together and fall to the ground and spread out. This is the right humidity."

There is no way. The old branch secretary and others are not familiar with this aspect. If they talk about the proportion, they will definitely not be clear. It is better to say it in plain words so that everyone can understand.

The old Party branch secretary suddenly realized and said gratefully: "Thanks to you, Expert Wang, for helping me understand so many things. Let's make improvements according to what you said."

After discussing chicken manure fertilizer with the old branch secretary, expert Wang, fully aware of the key role of soil quality in crop growth, decided to conduct a comprehensive inspection of Zhoujiazhuang's geology.

He first selected several representative points in different areas of the experimental field. He held a professional soil sampler, inserted it into the soil, then rotated the sampler, slowly pulled it out, and took out a complete tube of soil sample.

He carefully placed the samples into special sample bags and marked them.

Back at the makeshift laboratory, Expert Wang began a detailed analysis.

He first sieved the soil with a sieve to separate particles of different sizes and observe the texture of the soil.

Next, he took some soil and put it into a test tube, added specific chemical reagents, and detected the pH value of the soil by color changes.

At the same time, he also used precision instruments to measure the nutrient content of the soil, such as the proportions of nitrogen, phosphorus, potassium and other elements.

After a series of rigorous operations and analyses, expert Wang had a clear understanding of the soil conditions in Zhoujiazhuang, laying a solid foundation for the subsequent formulation of more precise planting and improvement plans.

Expert Wang said during the inspection: "The soil in Zhoujiazhuang is acidic, so we need to add some alkaline ingredients to the fertilizer to achieve an acid-base balance and provide a more suitable growth environment for crops."

As he spoke, he picked up a branch from the ground and drew a diagram on the soil, vividly explaining to Zhou Yimin and others the functions and proportions of various fertilizers.

Zhou Zhiming took out a notebook and kept writing down what Expert Wang said. He would not be able to remember everything if he just said it once, and with the notes, it would be convenient to ask questions later if he didn't understand.

Expert Wang feels that although Zhou Zhiming and his colleagues do not have a high level of education, they have a positive and adventurous mindset.

This reminded Expert Wang of the villages he had visited before. The villagers had lost hope in their difficult situations and were just numbly waiting for fate to take its course.

Time passed quickly, and before I knew it, it was getting dark.

Expert Wang then said, "Could you please help me build a bed here, Yimin?"

Here you can observe what is happening in the experimental field at any time.

Zhou Yimin quickly said, "Expert Wang, how can I let you sleep here? Come to my house! I have a spare room."

The old branch secretary also echoed.

In the end, there was no choice but for Expert Wang to agree.

Zhou Yimin looked around and saw that it was getting late, so he said, "Expert Wang, it's getting late now. Let's eat first. There's no rush for this kind of thing."

Expert Wang also understood and had no choice but to agree.

After having dinner at Zhou Yimin's home, expert Wang went for a walk in the village alone.

The moonlight sprinkled in the village, covering the entire village with a layer of silver gauze, and occasionally the villagers' laughter could be heard. Expert Wang walked along the path, feeling a lot of emotions in his heart.
