The mill paid on the twenty-ninth. Janelle knew because Gary texted her a picture of the propane ticket at 8:02 that morning, no words, the delivery man's thumb in the corner of the frame.
The forward came back on the first. On the fifth it rained half an inch onto ground that was soft on top and still frozen at six inches, and the tile on County 14 ran thin and clear, and SE-0611 was on the station board again like nothing had ever happened to it.
FORWARD LOT 41 T: NITRATE, SO4, CA, MG.
Not K. K was never on the forward. K was her.
She filled bottle A and bottle B at the lip, read 1.8 C off the thermometer, and wrote HOLD-BY 2/19 on the tape in grease pencil. On the bench she checked the K box herself. The planner had pushed a mid-year supplemental onto FY2048 Monday, an amendment line in the middle of a budget that had been open since July: LAB ADD-ON SUBLINE: $150.00. Somebody in Springfield had found thirty dollars in February. Nobody finds thirty dollars in February for inflation. She did not know whether it was because of her, and she was not going to call Springfield to find out.
$11.00. Subline: $139.00.
Dale read the numbers out at 1:40 the way he read everything, like a box score.
SE-0611: NO3-N 9.2. SO4 31. CA 64. MG 22. K 2.6.
"Two point six," he said. "Baseline's two. You've got maybe one more wet week where you can tell."
"Then it's gone."
"From the pipe."
Three hours, white. The planner didn't flag anything. It was the first sample in three months nobody had to argue about, and she sat in the truck afterward with the heater on and didn't put it in gear for a minute.
16. FORWARD BACK. MILL PAID THE 29TH. K 2.6, MY $11. HOURS WHITE. ONE MORE WET WEEK TO SEE IT.
Dale stayed late Wednesdays because his wife had choir. She brought the protocol on paper because he would not read anything on a screen that was longer than a text.
Page one, top line, the way Kuhl had told her: THIS IS NOT A VALIDATED METHOD.
He read all four pages with a red pen. The radiator under the window knocked twice. He did not say anything until the end.
"You've got one site."
"I've got fourteen."
"You've got one pile and fourteen fields it went on. That's one event." He tapped the page. "A method is something somebody who doesn't like you can do on a different pile and get the same answer."
He circled DETECTION WINDOW: 7 WEEKS. "Seven weeks on silty clay loam in a wet November. What's it on sand? What's it in a dry spring?"
"I don't know."
"Then write that."
He put three things in the margin. A field blank every run, deionized water through the same kind of bottle, so nobody could say her bottles were dirty. A duplicate on every fifth outlet. A hold-time study: K at day one, day seven, day fourteen in the locker.
"Because bottle B sat fourteen days raw," he said. "No filter, no acid. Filter it at the lip and acidify it, K sits still for six months and nobody argues. Raw tile water with any clay in it, the clay gives K back into the bottle while it sits. That's what YardDesk says if they've got a chemist."
"It ran clear on the fifth."
"Then make clear count. Filter one at the lip, point-four-five, nitric vial. Leave one raw. If raw and filtered match at fourteen days, the clay didn't do it." He handed the pen back. "And get a second district. Somebody whose mill blends."
She typed it in the truck under the yard light. The planner offered to fill in SCOPE. What it offered was APPLICABLE TO ALL AG LIME LOTS. She deleted that a letter at a time and typed: TESTED ON ONE EVENT. PEKIN YARD. SILTY CLAY LOAM. NOV 2047 TO FEB 2048.
She ran the hold-time study the next week because it was the one Dale said would hurt her. Three bottles off SE-0611 at the same pour, February twentieth, 2.0 C at the lip, the water running thin and clear the way it had on the fifth. Bottle one to the bench the same afternoon. Bottle two she pushed through a 0.45 syringe filter at the lip and capped over the nitric vial, her thumb numb on the plunger. Bottle three raw, the way bottle B had gone. Two and three into the locker on the shelf where bottle B had sat in December, the logger clipped to the rack so the planner could see the temperature every ten minutes and nobody could say later that it hadn't.
Day zero, 2.4. Day seven, raw 2.4, filtered 2.4. Day fourteen, raw 2.5, filtered 2.4.
Dale looked at the third number a long time. "Point one is inside the instrument," he said. "Write it as no change. Don't write it as proof."
She wrote: NO CHANGE DETECTED, DAY 0 TO DAY 14, RAW VS FILTERED, N=1. The planner flagged N=1 in yellow without being asked, which was the first time she'd agreed with it all year.
17. PROTOCOL, DALE'S RED PEN. ONE PILE IS ONE EVENT. BLANKS, DUPES, HOLD-TIME. NEEDS A SECOND DISTRICT.
The Mason County sampler was Ines Okafor. Janelle had met her once, at a bottle-handling training in 2045, and remembered her because she'd brought her own thermometer and argued with the instructor about it and been right.
Janelle called at lunch from the cab, phone propped on the dash against the windshield.
"You're the potash lady," Ines said. She was chewing something. "Your docket strip came through our feed. 'Technician's tracer sent to committee.' Everybody read it. You're a little famous in a way nobody wants."
"I need a second district. Somebody's mill that blends."
A pause. "Havana mill. I've got a lot cert from last fall says CALCITIC LIME, PROCESS FINES. I asked what process. Nobody could tell me what process."
"Did you run K?"
"Why would I run K. K's not on the forward." Then slower. "I've got four outlets on that lot. Sandy. Mason's all sand."
Sand was the thing Dale had circled. Janelle didn't say so.
"Field blank, a dupe every fifth, hold-time on one," she said. "Eleven bucks a bottle. If your subline's like mine, it's a hundred fifty."
"Ours is ninety. They didn't bump ours." Ines laughed, and it wasn't happy. "I'll do the next wet week. If my supervisor asks, I'm telling him it's your fault."
"It is."
"Send me the protocol. The one that says it isn't one."
She emailed it from the cab, subject NOT A METHOD (YET). The planner tagged the message EXTERNAL, CROSS-DISTRICT and asked if she wanted to log the call. She logged half an hour.
0.5 H: OUTSIDE FORWARD SCOPE.
Grey. She left it.
18. CALLED INES, MASON. HAVANA MILL, "PROCESS FINES." SAND. HER SUBLINE IS 90. HALF HOUR GREY.
Donna had the co-op probe, the chrome one with the T handle, and a paper grocery bag with three sample bags inside, already labeled in marker: 0611 A, 0611 B, 0611 C.
Janelle had come because Donna asked her to come. Not to do it. She stood at the end rows with her hands in her coat pockets and her card in neither of them.
Donna paced it off from the 2046 soil map, the one that had been on the fridge under the seed-corn magnet, now folded in quarters and soft at the creases. Twenty steps in from the waterway. Ten cores per bag, zigzag, seven inches, the way the co-op sheet said. She pushed the probe in with her boot. It went in easy. The ground smelled like March, which is to say like a basement.
Gary watched from the shop door and didn't come out.
"Is that deep enough," Donna said.
"That's what the sheet says."
"I'm asking you."
"It's what they pulled in '46. Same depth, same number. That's what makes it yours."
Donna drove the bags to the co-op herself. Twenty-two dollars each on the farm account.
A week later, Friday, 3:40, she called. She didn't say hi.
"A, 201. B, 196. C, 188. It was 168."
"Twenty, thirty up. Like Dale said."
"The man at the counter says that's good. He says we can skip potash this year." A long breath down the line. "So it was fertilizer."
"It was fertilizer. It also wasn't lime. Both."
"I put the paper in the folder with the mill letter." Then: "Gary wants to know if they'll ever say it went on us."
"The committee meets Wednesday."
Donna hung up without saying goodbye, which was how she ended the calls she was satisfied with.
19. DONNA PULLED HER OWN. 168 TO 201, 196, 188. SKIP POTASH. HER PAPER, IN THE FOLDER WITH THE MILL LETTER.
The committee was three people on a screen in Springfield and one in the room, plus the planner, which chaired because nobody else wanted to. The agenda had her as item four of seven. Item three was a revised font for bottle labels. It ran eleven minutes.
She had ten. She used seven.
Page one first, out loud. This is not a validated method. Haskell from Springfield nodded at that, the first time anything on the screen moved.
Then the curve. 6.4 in December, 3.4 at the thaw, 2.6 in February. Hartsburg north flat beside it at 1.9, 2.0, 1.9, the control, the field the mill's ash never touched, so nobody could say it was just the weather. Then Ines's numbers, which had come in Monday: two of four sandy outlets on the Havana lot at 4.1 and 3.8 after the February rain. Field blank clean. Duplicates inside ten percent. Hold-time: same locker, same shelf, new pour, raw against filtered, day zero to day fourteen, flat. N=1. "Not bottle B," she said, because if she didn't say it somebody would say it for her.
The planner put a line on the shared screen under her last slide.
SECOND DISTRICT SIGNAL CONSISTENT. N=2 EVENTS.
Then a second line, in a different color, because it came from outside the district.
YARDDESK (MACKINAW MILL), FILED COMMENT: TRACER CONFOUNDED BY GROWER-APPLIED POTASH. NO GROWER APPLICATION RECORDS ATTACHED. REQUEST PROTOCOL BE TABLED.
The mill's agent had read the draft. Of course it had. She'd sent it to Ines with no lock on it, and Ines's district shared a feed with the docket.
She didn't answer it on the screen. She held up Donna's co-op sheet to the camera instead, the paper one, the soil test with the farm account number on it, 168 in 2046 and nothing applied since, and then the co-op's letter from December that said zero potash sold to fourteen of fourteen lot 41 T fields in the 2047 season.
"Those are the application records," she said. "They're on paper because the grower pulled them." Then the number Dale had worked out on the back of a lab tag. "Thirty parts per million on silty clay loam is a couple hundred pounds of K2O an acre. Most of it goes to the clay, not the test. At two ton of lime an acre, that's several percent potash in the lot. Nobody spreads that by accident. That's not process fines."
The planner took a photo of the sheet through the room camera and attached it to item four. Then it split YardDesk's comment in two. The SE-0611 half greyed out and went under a fold that said SUPERSEDED BY EXHIBIT. The other half stayed black.
FIELDS 2-14: OPEN. NO GROWER RECORDS ON FILE.
Haskell looked at the black half longer than the grey one. The co-op letter said the co-op sold none. There was another co-op in Delavan. Janelle had thought of that in December and hoped nobody else would.
Haskell unmuted.
"We can pilot this in 2049. Two districts, possibly four. Detection only."
"Meaning."
"Meaning a tracer hit flags a lot for review. It does not apportion a deduction to a field. The five-and-a-half rule stays. If we start allocating carbon by your numbers, every mill in the state litigates every bottle, and we don't have the hold-time data to survive that yet. You don't either. You have one hold-time study."
Which was fair. Which was also exactly the thing it had been for. Gary's five-and-a-half, taken off a field the ash had barely reached, so a field it had buried could pay less. That was why she'd started. Card one, line one.
The planner offered two buttons.
ACCEPT PILOT SCOPE AS PROPOSED. REQUEST REVISED SCOPE (DEFERS TO JUNE).
June was after planting. In June the tile would be dry and there'd be nothing in it to see. A pilot in 2049 meant bottles at the lips this fall, in two counties, maybe four, with blanks and dupes and a page one that said what it was, and thirteen farm accounts to ask for paper before then.
She pressed accept.
There was a comment box, so she typed in it.
TECHNICIAN REQUESTS ALLOCATION BE REVISITED AFTER HOLD-TIME DATA. MASON CO. SUBLINE IS $90.
Haskell read it. For a second she didn't say anything. Then: "Noted on both."
The planner moved to item five.
In the truck she wrote the card with the engine off.
20. COMMITTEE: PILOT 2049, DETECTION ONLY. NO ALLOCATION. TOOK IT. ASKED THEM TO COME BACK TO IT. TOLD THEM ABOUT INES'S 90 BUCKS.
Card five was full. She turned it over. On the back the kid had drawn a dog, or a cow, in purple, sometime in December. She left that and started card six.
Then she texted Gary, because Donna had asked the question and Gary had asked her to ask it.
They won't say it went on you. They'll say next time where it goes.
The dots came up and went away twice. At 4:51:
Donna says thats something.
At 4:52:
I say its not the same thing.
He was right. She put the phone face down on the seat and drove to Hartsburg north to look at a dry tile, because it was on the way, and because in October it would be running again.
