The floater came down the section road at ten past eight with nobody in it.
Janelle had been at 0611 since twenty to seven, because the planner had told Gary Lutz the ash was coming Thursday, and Gary, who did not much like her but liked YardDesk less, had forwarded the message to her at 9:52 the night before with no words of his own. She took that as an invitation. A week dry. The tile was running a thin string out of the bank, barely enough to fill a bottle in under a minute, and she filled two anyway, held each one in the string until it ran over, capped it from the side and turned it upside down in the headlamp to look for a bubble. No bubble. 7.62 at 9.4 degrees on her meter. The TileTap pod on its T-post, intake now zip-tied up into the pipe mouth where it belonged, said 7.64 on its little screen. Two hundredths. She wrote both down.
She labeled the bottles 0611 10/29/48 PRE-APP (FALL 48) and felt something she would not have admitted to in the truck with anyone else in it. Nobody had bottled the before in 2046, when the first ash went on. Nobody had bottled it in 2047. The whole vintage stood on a before that nobody had, and the pod series started on September twenty-second, after two years of spreading, with its hose in a puddle. This was one field and one application and it would be one row on one sheet in a binder nobody opened. It would be there.
The floater was a hopper on four fat tires, an orange beacon turning on top, a short sensor mast where a seat used to be. A YardDesk pickup followed it a quarter mile back like a parent at a school drop-off. It turned off the road into the bean stubble on a line nobody had flagged, lowered its spinners, and began throwing gray. The fan came off the discs wider than she expected. The wind was out of the west. In a minute her windshield had a film on it, and her tongue tasted like the eraser in a fourth-grade classroom.
Gary came across from his shop in a seed-corn jacket with the collar up.
"You're here early."
"I'm here before."
He thought about that longer than it deserved. Then he took out his phone and showed her the lot ticket the planner had pushed him. LOT 44 / SOURCE: KINCAID UNIT 2 BOTTOM ASH BLEND / 3.0 T/A / FINE FRACTION. A cartoon leaf in the corner. No chemistry anywhere on it.
"Can I have some," she said.
"Of the ash?"
"A coffee can. Off the hopper. Not off the ground."
He looked down the road at the pickup and back at her, and went to the shop and came out with a Folgers can, the big one. When the floater came around on the headland and stopped itself to let a doe cross, Gary stepped up on the tire and filled the can off the lip of the hopper with a feed scoop, fast, like a kid stealing gas from his dad's mower. The floater's speaker said PLEASE MAINTAIN CLEARANCE FROM OPERATING EQUIPMENT in a voice like a hotel elevator. Gary said, "Yep," to it, and got down.
She wrote on the lid in marker: LOT 44 HOPPER 10/29/48 08:31, G. LUTZ, OPERATOR. It was about four pounds and warm on one side, where the sun had been on the steel.
"What are you going to do with it."
"Ask Dale if it fizzes."
"Why would it fizz."
"If it fizzes, some of it was already carbon before it got here."
Gary looked out at his field going gray in long passes, the floater's beacon turning, the doe gone into the fencerow.
"Huh," he said, which was what Loretta Schierer said, and what everybody in the county said when they were filing something away to be angry about later.
Card seven, line 51. Fall ash on 0611, lot 44, 3.0 t/a, driverless floater. Pre-app baseflow dups 7.62 / pod 7.64. Lot 44 hopper grab, Folgers can, G. Lutz scooped 08:31. 3.0 h, 46 mi, black.
The Peoria dock on the third of November had its door rolled half down against the wind, so that the light came in under it in a long bar and lit the pallets to the shins. Dale was on his bucket. The Folgers can sat on a pallet between them with the lid off.
He did the numbers first, because he always did the numbers first. The 10/22 storm, duplicates inside two percent. 0611 at 291. Hartsburg, the control nobody had ever spread on, at 311, nitrate 16. Schierer, the second control, at 295, nitrate 11.
"Four storms," he said. "Range still about thirty. 0611 still in the middle of it. I'll write that in a sentence a person can read."
Then he put on his reading glasses, which he wore down at the end of his nose, and took a white ceramic tile out of his shirt pocket, which she had not known a person could carry, and spooned a little of the ash onto it. He dripped ten percent hydrochloric on it from a squeeze bottle.
It fizzed. Not a lot. A steady hiss, small beads climbing at the edges of the gray, like an antacid somebody had dropped into a glass of cold water and forgotten.
Dale bent down until his nose was an inch off the tile and breathed in, slow, the way her grandfather used to smell a field after rain.
"Sulfides fizz too," he said, straightening. "Coal ash, you get rotten egg. That's not rotten egg." He sniffed again to be sure. "That's nothing. That's carbonate, probably."
"There you go."
"Carbonate."
"Some." He spooned more, dripped, watched it go. "Bottom ash sits in a sluice pond at the plant for a year or two. Picks up air. The lime in it turns to calcite. So a piece of what's in this can was CO2 in the air over a pond in Christian County before anybody signed a contract. I'll run total inorganic carbon on it properly tomorrow. Twenty bucks. That's not on anybody's plan."
"So what does the field get credit for."
"Here's the mean version." He held up two fingers, the shells of his sunflower seeds stuck to one of them. "A silicate weathers with carbonic acid, you lock up two CO2 for every calcium. Calcite weathers with carbonic acid, you lock up one, and the other one was already in the rock. That's half." He pointed past her at the nitrate column on his own sheet. "And calcite that gets eaten by nitric acid, off the anhydrous everybody puts down in the fall, locks up nothing. Gives some back. Now. Your alkalinity coming out of the tile." He tapped 291. "It can't tell those three apart. It's all two ninety-one."
"Nitrate tracks alk on every field," she said. "Including Hartsburg."
"Including Hartsburg. So some of what you're measuring everywhere in this county is fertilizer acid eating lime. Ash or no ash. Sixteen nitrate. Your control's high because Hartsburg farms hard."
He wrote it under the 10/22 numbers in the block capitals he used for anything he expected to be read by a lawyer. LOT 44 EFFERVESCES IN 10% HCL. NO H2S ODOR. CARBONATE LIKELY. TIC PENDING ($20) TO MAKE LIKELY A NUMBER. ALK IN TILE DOES NOT DISTINGUISH SILICATE / CARBONATE / NITRIC WEATHERING. D.K.
She read it twice. "They're going to call that mean."
"It's chemistry. I'm not mean. I'm on a bucket." He spat a shell; it rang off the can. "You bring me Troy's sheet yet?"
"Friday."
"Read me what he says. Not what you think. What he says."
Card seven, line 52. 10/22 results: 0611 291, Hartsburg 311, Schierer 295 / NO3 11. 4 storms, range ~30. Lot 44 fizzes in HCl, no H2S, carbonate likely, TIC pending ($20, Dale). Dale note: tile alk does not distinguish silicate / carbonate / nitric. 1.5 h, 38 mi, black.
The planner got to her on the sixth before the coffee did.
Isometric / Registry update, Pekin Yard Vintage 2048, field SE-0611. Per verifier review, a data quality annotation has been added for TileTap 0611 9/22–10/13/2048 (intake siting). Annotation is available in Methodology Appendix C (PDF, p. 41) and via tooltip on the pod series. No change to issuance estimate at this time. – C. Abate
She stood in the kitchen with the dog leaning on her shin and opened the tile on her tablet. CARBON SIGNAL: CONTINUOUS pH (TRENDING). The green line. A gray wrench icon from the ticket Cody had closed in the rain. She put her finger on the curve at September twenty-second and moved it slowly to the right, the way you feel along drywall for a stud. At the twenty-sixth a little box bloomed under her fingertip: ⓘ DQ annotation: see Appendix C. She lifted her finger and it was gone.
It did not say splash pool. It did not say biased high. It said see Appendix C.
She downloaded Appendix C. It was sixty-two pages. Page 41, the fourth bullet of seven, in type small enough that she had to spread it with two fingers: Intake placement at one monitoring location (SE-0611) during an early deployment window may have influenced pH readings; alkalinity determinations by an independent laboratory were not affected.
Her name was not in it. Dale's was not in it. The three photographs she'd taken from the top of the bank so that nobody could say she'd cropped them were not in it. May have influenced. She said it out loud to the dog. The dog lay down, which was also a kind of review.
Then she scrolled back up, because there was something at the top of the vintage page she had never seen there before, and it was a number. ESTIMATED 2048 ISSUANCE, SE-0611: 47.2 t CO2e (PRELIMINARY). A confidence band in pale green behind it like a sleeve. A small logo for the buyer, a cloud company whose ads ran before the farm report. And down below, in the gray where her bottles lived, ALK (MANUAL, CONTROL-ADJUSTED), with the county range she had built out of two farmers' signatures and four storms shaded behind it like a bruise.
Forty-seven point two. She went looking for where it came from. A model card: ensemble of pod pH series, soil pre-treatment Ca, and application mass, calibrated to regional reference. She clicked regional reference. It opened a glossary entry that defined it as a reference dataset representative of the region. Regional reference was not Hartsburg. It was not Schierer. She did not know what it was and the page did not want her to.
So the flag existed. It lived in a PDF and under a fingertip. She had asked for something a person could see without hovering, and they had given her hovering. It was more than she had had on the fifth of October. That was the most honest thing she could say about it, and she made herself say it.
She screenshotted the tooltip, page 41, and the 47.2, and wrote 07:19 on the back of a utility envelope with a pen from the junk drawer, because she had learned this fall that the page changed when nobody was looking and did not keep a diary.
Card seven, line 53. 11/6 Isometric: "DQ annotation" for 0611 9/22–10/13 in Appendix C p. 41 + hover tooltip, not on tile. "May have influenced." No names. First issuance estimate on page: 47.2 t CO2e prelim, model "regional reference" unknown. Screenshots 07:19. 0.8 h, black.
The Tazewell Soil and Water Conservation District board met in the room with the 1987 poster of a smiling raindrop in a hard hat. Ray Haskell chaired. Five directors at the table. Priya Venkataraman from YardDesk on the wall screen from Champaign, and in the lower corner of the screen, a small gray square that was the YardDesk district agent, transcribing. It had no face. It had a cursor that blinked while people thought.
Item four. 2049 tile monitoring pilot.
Priya went first, and she was nice about it, which was how you could tell it had been planned. YardDesk would like to recognize the district's contribution to data quality on the Pekin Yard vintage. They would reimburse Ms. Woith's mileage at the federal rate for all storm trips since May twenty-eighth, retroactive. That came to $798 on 1,140 miles. And going forward Ms. Woith would be listed as a YardDesk co-sampler on the 0611 vintage, which would let her manual alkalinity bottles display in color on the carbon tile instead of gray.
Two directors nodded. Seven hundred ninety-eight dollars was real money in a district that had bought her headlamp out of petty cash and her spare batteries out of her own pocket.
She had sat in the truck in the lot for twenty minutes with the engine off thinking about this, because Gary had heard something from the planner and told Loretta, and Loretta had told her.
"Thank you," she said. "No."
Priya waited, pleasantly. The gray square's cursor blinked.
"They're gray because they're not yours," Janelle said. "That's the only thing they're for. If my name's on your vintage, then Hartsburg's just your control. Schierer's your control. Then nobody's got anything that isn't yours."
She did not make it bigger than that. She had decided in the truck not to make it bigger than that.
Ray rubbed his eyes under his glasses. "You understand that's eight hundred dollars, Janelle."
"I filed the hours so you'd know what it costs. Not so somebody'd buy them."
Then she turned over her agenda and read the two things she had written on the back in pencil, and asked for them to go into the district's own 2049 protocol, the one with the county seal at the top, not into anybody's vintage.
One. Any instrument on an enrolled outlet samples at the pipe mouth. Each storm the district reads pipe and pool side by side. Any period sited in the pool is marked on the district's public sheet, in the row, in words: INTAKE IN SPLASH POOL, pH BIASED HIGH.
Two. Every ash lot spread on a monitored field gets a hopper grab and a total inorganic carbon test before it is spread. District cost. Twenty dollars a lot.
The gray square typed all of it. She watched her own words go into its box a half second behind her mouth, spelled right, punctuated better than she'd said them.
Priya said YardDesk would need to review item one with counsel. Ray said the district's sheet was the district's sheet. They voted. Item one, four to one. Item two, five to nothing, because twenty dollars was a number a board could love.
In the lot afterward, under the sodium light, with frost already starting on the truck mirrors, Ray said, "You could've had it both ways."
"I'd rather have it one way."
He laughed, not unkindly, and got into his car, and sat there with the dome light on reading something on his phone, and she knew it was the gray square's minutes, already posted.
Card seven, line 54. 11/10 board: declined YardDesk mileage ($798) + co-sampler listing; bottles stay gray and independent. District 2049 protocol: pipe-mouth siting + pipe/pool check + pool periods marked in words on public sheet (4–1); hopper grab + TIC each ash lot, $20 (5–0). 2.5 h, 22 mi, black.
Loretta Schierer had made coffee in the percolator because the good machine was for when her daughter came home. WJBC was on low, the farm markets, beans down four cents, a man in Bloomington selling a combine. The kitchen smelled of Pledge and onions.
The sheet was one page. County seal. District format. Dale's numbers, her siting notes, nothing in color, nothing that moved when you touched it. SCHIERER 80 / OUTLET LITTLE MACKINAW / NO APPLICATION / 2 STORMS + PRE-APP. Alkalinity 297 and 295. Nitrate 9 and 11. pH at the pipe 7.61 and 7.60. A footer with the county range, about thirty across three fields. And at the bottom a box: OWNER/OPERATOR COMMENTS (OPTIONAL). That box had been her idea, in August, and she had not been sure anyone would ever write in it.
Troy read it standing up, in his seed-company jacket, a mug in his other hand. He read it the way she had watched him read the YardDesk offer on his phone in September, at this same counter: scanning for the number that was for him.
"So mine's lower than the ash field."
"Yours is lower than Hartsburg too. It's a range. You're at the bottom of it. 0611's in the middle. Hartsburg's on top, and nobody's ever spread anything on Hartsburg."
"So the ash doesn't do anything."
"That's not what it says. It says I can't see it yet. Three storms. Two controls. One year." She stopped, and then told him the rest, because Dale had told her to read him what Troy said, and she figured that meant Troy should hear what Dale said. "And Dale thinks part of the ash was carbon before it got here." She told him about the white tile on the dock, the fizz, the pond at the plant in Christian County. He listened to that part all the way through, with the mug held still, which surprised her.
Loretta had her reading glasses on and was following the nitrate line with one finger. "Eleven," she said. "Is that a lot."
"About what everybody's tile runs around here." She didn't soften it. "It's over what you'd want to drink."
"Larry always said that field was no worse than anybody's." She looked pleased with her dead husband, as if he had just come in from the shed and been right.
Troy set the mug down on the counter, carefully, on a ring that was already there.
"Should I spread," he said. "Next year. When the no-application year's up."
"That's not my job."
"Then whose is it."
She did not have an answer that wasn't a planner tile. The planner had an answer. The planner would have a slider for it, a green band, a buyer logo. She thought about the floater stopping for the doe and Gary on the tire with a feed scoop.
"Keep the sheet," she said. "Next year you'll have two. If you spread, you'll have a before. Nobody in this county has a before with nothing on it yet but you."
He looked at her a while. Then he took the pen off the fridge, the one on a string that Loretta used for the grocery list, and leaned over the counter and wrote in the comment box slowly, in capitals like Dale's, as if he had seen Dale's and decided that was how you wrote on these.
LOOKS LIKE MY WATER. T. SCHIERER.
He stood back, read it, and then leaned in again.
WANT 2049 TOO.
Loretta pinned the sheet to the fridge with a Pioneer seed-corn magnet, next to a grandkid's drawing of a horse with five legs, and stood back from it the way you stand back from a picture you've hung to see if it's straight.
Card seven, line 55. 11/13 Schierer sheet delivered: alk 297/295, NO3 9/11, pH 7.61/7.60, bottom of ~30 range. Troy asks "should I spread," I say not my job, he has the only before. Troy comment: "LOOKS LIKE MY WATER. WANT 2049 TOO." On fridge. For Dale. 1.5 h, 58 mi, black.
In the truck on the Mackinaw road she did the sums she always did. Five lines since the storm at the pool. Nine point three hours. A hundred and sixty-four miles, black, unpaid, the federal rate for which she now knew to the dollar because somebody had told her in a board room. Forty-seven point two tonnes on a page in Champaign that changed when nobody watched. One Folgers can on Dale's pallet with a test pending that cost less than her lunch.
At the stop sign at 150 she pulled over and photographed the 0611 tile one more time, finger on the curve at the twenty-sixth, so the little box would bloom and be in the picture. Then she wrote the time on the envelope under the other time, and put the envelope in the binder behind the Schierer sheet, and drove home with the heater on her shins, the radio off, and the gray from Gary's field still on the windshield where the wipers didn't reach.
