When we walked to the pits where earthworms were being cultivated through composting, Aunt Wu and Su Meilan were there as well.
They all looked a little uneasy, after all, they had been cultivating the plants using compost as instructed by Ning Jing.
Everything was fine a while ago, so why are all the earthworms gone this time?
If the farm doesn't do well, they'll definitely have to go back to working in the fields.
But working in the fields is nowhere near as easy as working at the farm. Not to mention, the hours are flexible. As long as it's not a shift, once you've finished what you're supposed to do, you can go home first.
Moreover, the work points you receive are the full amount. But when you go to work in the fields, the scorekeeper might not necessarily give you the full amount of work points.
Especially for women, if they can get you 8 work points, that's already considered good.
Compared to others, Aunt Wu was more agitated and uneasy.
After all, she's already so old, and she usually only gets a maximum of 6 work points when she works in the fields.
This job is so easy now; if she loses it, she'll cry her eyes out when she gets back.
“Ning Jing, believe me, I did everything you said, and I didn’t slack off at all.”
Seeing Ning Jing squatting beside the compost pile, clutching the soil in deep thought, Aunt Wu immediately became so anxious she almost cried as she explained to her.
"Aunt Wu, don't worry, let me see what the reason is."
Ning Jing turned around and comforted her, then brought over the soil from the pit next to her for comparison.
At first glance, the compost in the two pits looked no different.
However, it was quite obvious that in another compost pile, Ning Jing could easily see countless earthworms wriggling around inside just by digging around.
In the other pile of soil, not only were there very few earthworms when you dug them out, but they were also thin and long, looking like they were malnourished.
But how could the same composting method cause such a situation?
Ning Jing was completely baffled, staring at the two piles of manure, remaining silent for a moment.
Aunt Wu and the others dared not disturb Ning Jing's thoughts, and just stood aside anxiously.
Is it a problem with the soil?
After the consultants followed Tan Dingguo around the farm, they finally arrived at the pit where earthworms were being composted.
Seeing Ning Jing squatting by the pit in a daze, deep in thought, he couldn't help but ask softly what had happened.
Seeing the questioning look in Tan Dingguo's eyes, Wang Guihua had no choice but to recount what had happened.
Before Tan Dingguo's expression could change drastically, they heard Chen Daohui, who was standing behind them, say slowly.
Everyone, including Ning Jing, turned to look at Chen Daohui immediately.
He raised his hand and used his index finger to tap the glasses that had slipped down his nose.
Then he calmly said, "If you compost according to the usual ratio, and after each earthworm digging, you transport all the fertilizer from this pit to the field, then what about the newly dug soil?"
Can you guarantee that they were dug up from the same place?
Upon hearing Chen Daohui's words, Aunt Wu clapped her hands and said with a sudden realization, "Indeed, it wasn't dug from one place. The soil here was dug from the riverbank."
Because most of the soil on the hillside had been dug away, and the mud on the riverbank was also quite black, I figured I'd compost it all anyway, so I dug some mud from there for composting.
A glint flashed in Ning Jing's and Chen Daohui's eyes, and they said in unison, "The soil on the riverbank must have been polluted."
After they finished speaking, the two looked at each other again.
