The reading climbed.
The manager whistled.
“You didn't heat this?”
“No.”
“Nothing mechanical?”
“No.”
The boy opened his notebook.
“Temperature tells us whether decomposition is active.”
The manager wiped his forehead.
It was barely morning and he was already sweating.
“How often do you turn it?”
“Depends.”
“Of course.”
The boy ignored the sarcasm.
He showed him different piles.
One smelled earthy.
Another sour.
One remained pale and dry inside.
One had decomposed much more evenly.
The manager asked why.
The boy explained moisture.
Carbon.
Nitrogen.
Aeration.
Particle size.
He spoke cautiously.
Whenever the manager asked something beyond what he knew, the boy said so.
“I don't know.”
The manager noticed.
At first he interpreted it as weakness.
By the third hour he understood it was discipline.
The teenager did not need to sound certain.
He cared more about being accurate.
That made the manager increasingly uncomfortable about how confidently he had dismissed him.
They moved toward a row of black drums near the equipment shed.
“What are those?”
“Char.”
“You're burning my husks?”
“Some.”
“That defeats the point.”
“No.”
The boy showed him the low-oxygen system his father had built from the grandfather's original design.
The manager listened.
He did not understand all of it.
Neither did the boy.
But he understood enough to explain why partially carbonized material behaved differently from ash.
The manager rubbed a black fragment between his fingers.
“So this goes straight on the field?”
“Not usually.”
“Why?”
The boy smiled.
“Because everything I tried straight on the field when I was younger caused some kind of problem.”
The manager laughed.
“Finally something we agree on.”
The boy showed him records.
Plots with too much raw husk.
Plots where nitrogen shortage became obvious.
An over-charred section.
A compost pile that went anaerobic.
A treatment that seemed promising one year and disappointing the next.
The manager looked through the notebook more carefully this time.
“You kept all the failures.”
“Yes.”
“Why?”
The boy shrugged.
“They happened.”
Most adults the manager knew behaved differently.
They presented success cleanly.
They removed embarrassment from the story.
They made hindsight look like certainty.
The boy's notebook was the opposite.
Crossed-out assumptions.
Wrong guesses.
Bad results.
Questions.
The manager reached a page marked three years earlier.
RAW HUSK TOO THICK. CORN PALE. DO NOT REPEAT.
He looked up.
“You actually made it worse.”
“Yes.”
“For a whole season?”
“In that strip.”
“And you kept going.”
“Not the same way.”
The manager looked again at the thriving section.
The transformation suddenly seemed more impressive because it was not magical.
It had survived mistakes.
They reached the oldest experimental plot.
The boy's father joined them.
The manager looked toward him.
“You let him do this when he was nine?”
