Gary Holtz's north quarter is the first field the mill trucks reach coming out of Pekin. It's been that way since the ash contract, and the field shows it. In April they spread the ash thick, and five months later, wherever the combine hasn't been through yet, it still looks like somebody floured it for a pie crust and quit.
Tuesday, the twenty-eighth of September, 10:20 in the morning. Gary meets her at the shed with his reading glasses pushed up on his forehead and his YardDesk statement printed, folded in thirds, already soft at the creases from being shown to people. He's shown it to his brother-in-law. He's shown it at the elevator. The statement credits the north quarter with a soil carbon gain the size of a good year, and the reason is on page two in a little chart: the pod in his outlet pool reads 7.9 and climbing. The fleet model reads high pH as weathering. It reads weathering as carbon taken out of the air and locked in the ground.
"Best field I've got, according to them," Gary says.
"Let's get some dirt," she says.
She probes where the white streak is whitest, a pale band right down the middle of a pass where the spreader must have stuttered. Then she walks forty feet off it into plain brown loam and probes again. She lays the two cores on the tailgate and takes the dropper bottle out of the door pocket. It's dilute acid, the same bottle she uses to acidify iron samples at the pipe.
One drop on the streak core and it boils. A tiny white boil. She drops again and it does it again.
One drop on the loam core. A faint tick, and that's all.
"That's the carbon," Gary says, pleased, the way you'd be pleased at a calf standing up.
"That's carbonate," she says. "That's all a fizz tells you. It's in the streak now." She almost says the rest, that it came in on the truck, and doesn't, because she doesn't know what the mill sent. A lot of ash leaves a plant as burnt lime, not limestone. Lime lying wet in a field for five months pulls CO2 out of the air and turns into carbonate that fizzes exactly like this. "Either it was carbonate at the mill and it just moved here, or some of it was lime and it took a little out of the air on your ground, once. Either way it's not what the pH is paying you for."
He looks at the fizz for a while. The wind turns a page of the statement on the tailgate and he flattens it with his palm.
"They paid me for it," he says.
"They paid you for the pH." She bags the cores in two zip bags and writes on masking tape with the carpenter's pencil: HOLTZ-ASH, HOLTZ-OFF. "I'll get Dale to split organic from inorganic. Then you can see which is which on paper, and you don't have to take my word or theirs."
The outlet pool is on the way out, a concrete splash box at the end of the main with the pod bolted in the pool where all four thousand YardDesk pods live. Dry week, low flow. The pod reads 7.92. She holds her meter in the stream at the pipe mouth, before the water has fallen into anything: 7.81. Even here the pool runs high. Even on Gary's field, which nobody is fighting about.
123. 9/28/49 HOLTZ ASH FIELD: STREAK CORE FIZZ HARD, OFF-STREAK FAINT. CARBONATE IN STREAK; ORIGIN PENDING (MILL CERT? δ13C?). 2 BAGS TO DALE (ORG vs INORG C). POOL 7.92 / PIPE 7.81. G.H. 'THEY PAID ME FOR IT.' 1.1 H, 31 MI, BLACK.
Gary walks her to the truck. He doesn't say anything else about it. He folds the statement back into thirds along the soft creases and puts it in his shirt pocket, and he doesn't take it out again.
Thursday, the thirtieth, 2:10 in the afternoon. The district office. Q3 closes at midnight. Ray has been walking the hall since lunch with a cold coffee, saying "midnight" to people as if it might be news to them.
A second email from Dr. Kerwin. Short, like the first.
The registry issues credits by vintage, the calendar year the removal is claimed in. For the 2049 vintage on these four fields, how many observer hours stand behind the district readings? Black and gray separately, if you keep them that way.
She does keep them that way, and that's the trouble.
She takes cards nine, ten and eleven out of the drawer. They're rubber-banded together, and the band has gone sticky and left a brown stripe across the top of nine. The spreadsheet is open in the other window. She doesn't use it. She adds the hours with a pencil on the back of a Casey's receipt, because she wants the number to come out of the cards and not out of something she could fix with a click.
The black hours are the ones the county bills somebody for. She adds them twice, the second time from the bottom up. 61.4.
The gray hours are unbilled: arguing with vendors, driving to outlets nobody pays for, kneeling in a ditch at four in the morning so a dash would be a number. Since August they've been on the front of the card with the rest. Before that she wrote them in pencil on the back, smaller, like a confession. 38.7.
Then she turns the cards over. On the backs of nine and ten, from spring, there are hours she wrote down and never added up, because adding them felt like sending a bill. She adds them now. 9.5.
Then she reads his question again. On these four fields. The 61.4 has Gary's ash field in it, and a dozen outlets that aren't any of the four, and two afternoons on the phone with the vendor that weren't about any field at all. Some of the spring backs are from March, before the four were even on her list. An auditor will split them himself if she doesn't, and he'll split them his way. She draws a fourth pencil column down the receipt and heads it OF WHICH ON THE FOUR and goes through the cards a third time, line by line, field name by field name. 44.2. 27.9. 3.1.
She could send the 61.4. It's the official number, and it makes the district look like a contractor with a meter, which is what the registry is paying for. The 38.7 makes her look like a woman with no evenings. The 9.5 makes her look like a woman who kept a secret diary about dirt.
She sends all of it, both columns, labeled, and one sentence under them:
Gray hours are real observations. They are unpaid, not unwitnessed.
She copies Ray. He shows up at her door ninety seconds later with the cold coffee, reads it off her screen, and says, "You're going to get me asked about overtime."
"Probably."
He reads it again. "Send it anyway."
"It's sent."
He nods. He looks at the receipt with the pencil columns on it. "Keep that," he says, and goes back to saying "midnight" to people.
124. 9/30/49 KERWIN ASKS HOURS PER 2049 VINTAGE. COUNTED FROM CARDS 9-11: BLACK 61.4, GRAY 38.7, SPRING BACK-OF-CARD 9.5; OF WHICH ON THE 4 FIELDS 44.2 / 27.9 / 3.1. SENT ALL, LABELED. 'UNPAID, NOT UNWITNESSED.' 0.9 H, GRAY.
She tapes the receipt to the back of card eleven. Gray hour, because counting your own hours for an auditor doesn't bill.
Tuesday, the fifth of October, 4:40 in the afternoon, Tremont. No bread this time. Ilene has moved on from zucchini to apples, and Janelle brings a grocery bag of them from the tree behind Ilene's garage. They're small and bruised and smell like cider already. Dale takes one, looks at it as if it might be a sample, and puts the bag under the counter. "Down payment," he says.
He's holding the sheet against his chest. That means it's interesting.
"Guess," he says.
"Ash is mostly inorganic."
He turns it around.
HOLTZ-ASH: TOTAL C 3.1%. INORGANIC (CARBONATE) C 2.6%. ORGANIC C 0.5%.
HOLTZ-OFF: TOTAL C 2.4%. INORGANIC 0.1%. ORGANIC 2.3%.
SCHAEFER #17 9/15 FILT: DISSOLVED FE 2.4 mg/L. SO4 236.
"Your ash streak has less organic carbon than the dirt beside it," Dale says. "It's white because it's carbonate. Somebody's paying for carbonate."
"Where'd it come from," she says. "Truck or air."
"This doesn't say." He taps the 2.6. "Ask the mill for the ash certificate on the April loads. Lime and loss on ignition. Or I send a split out for carbon isotopes. Ground limestone sits near zero. Carbonate that grew in the field from lime and air comes out ten, twenty-five below." He shrugs. "If some of it came out of the air, it's a one-time pickup. A fraction of what the pH is crediting him. Every fifteen minutes."
She writes MILL CERT on her hand.
She reads the top two lines a second time, then the third, which is the one that makes her sit down on the stool by the sink.
Ken's water, filtered and acidified at the pipe in a dry week, the way Dale asked for it, is carrying dissolved iron. Iron only stays dissolved in water that hasn't met air.
"Point four five filter," Dale says, watching her face. "Fine rust goes through that. Comes out on the ICP as dissolved. Two point four in a dry week, I'd bet reduced. But it's a bet." He opens a drawer and puts a little foil box on the counter next to the apples. Ferrous iron kit, phenanthroline, the kind that turns orange in a vial. "Read it at the pipe, five minutes. Then it's not a bet."
She puts it in her jacket pocket. One more gray minute per site. So in the middle of September, twenty-two days without rain, water was probably still coming out of the gray pocket under Ken's old splice reduced, egg-smelling, carrying iron and sulfate out the tile. The pocket didn't heal over the summer. At most it slowed down.
"Ken's pocket," she says.
"Is my retirement," Dale says, and bites the apple.
She photographs the sheet on the counter. The bag of apples is in the corner of the frame by accident, with a bruise showing. She looks at it on the phone and decides to keep that one.
125. 10/5/49 DALE: HOLTZ ASH TOT C 3.1 / INORG 2.6 / ORG 0.5; OFF-STREAK ORG 2.3. ASH = CARBONATE, NOT SOIL CARBON; ORIGIN PENDING. #17 9/15 FILT FE 2.4 (0.45, COLLOID POSSIBLE), SO4 236 DRY = POCKET LIKELY STILL REDUCING. FE(II) KIT AT PIPE NEXT. 0.6 H, 18 MI, BLACK (K.S. INV).
Black, half of it on Ken's invoice. Gary's half she'll eat. Nobody pays the district to tell a man his best field is mostly carbonate.
Saturday, the ninth, 2:30 in the morning. The planner said sixty percent for the second week, and for once it was being modest. It came in Friday night and hasn't let up. 1.3 inches by two. The gauge on the porch post has overflowed its inner tube into the outer one, which she has to pour off and measure in the kitchen with the flashlight in her teeth.
The sticky note is on the dash, written at supper so the 2am version of her can't argue: SCHIERER + BAUER. Under it, smaller, the reason, because she writes the reason now: 0611 had S6 + S7. BAUER NEEDS WET-SEASON FLUSH. 0611 gets the dash. She chose it, and the note says so.
Schierer, 3:15. No porch light. Loretta has given up on her or slept through it. The pipe is running full and loud, and inside the mouth the bracket shines in the headlamp, the pod clamped to it where Cody put it. She kneels on the feed sack. The feed sack has dried since September and is about to stop being dry.
Meter in the stream an inch from the pod's nose. 7.58. Rinse, again. 7.58.
On Troy's feed, thumb wet, three tries to wake the screen: pod 7.58.
No gap at all. She distrusts it for a second, the way you distrust a bathroom scale that reads exactly what you hoped. Then she looks at the bracket, at the water going past both probes in the same inch of pipe, and lets it be what it is. Same water, same minute, two instruments, same number. That's what a pod is supposed to do when somebody mounts it where the manual says.
Bauer, 4:20, the clay outlet near Delavan running murky. The water is cold on her wrist through the gap between glove and sleeve. Meter 7.72. Two bottles: one filtered through the syringe and acidified at the pipe with a drop from the dropper bottle, one raw. Masking tape, BAUER-S8. She sniffs the pipe mouth the way she would at Ken's. No egg. Wet clay, and corn residue going sour in the ditch. A control, smelling like a control.
She sits in the truck with the heater on her feet and writes the table on the clipboard under the dome light. Raw, no adjustments, a dash where she wasn't:
STORM 8: 0611 PIPE – / 0611 POD (POOL) 7.67 / SCHIERER METER 7.58 / SCHIERER POD 7.58 / HARTSBURG – / BAUER METER 7.72
126. 10/9/49 STORM 8 1.3 IN. SCHIERER METER 7.58 / POD (PIPE) 7.58 = PAIRED 3 OF 3. BAUER 7.72 + 2 BOTTLES (WET FLUSH). 0611 DASH (MY CHOICE, POD ALONE 7.67). 2.4 H, 61 MI, BLACK.
She drives home at five with the wipers on high and the radio on the overnight farm report, a man in Iowa reading hog futures in a voice like he's apologizing for them.
Monday, the eleventh, 9:05 in the morning, Schierer's lane. The ground is too wet to drive the field, so they walk it, her boots and a new pair.
Ticket 44817 updated on Sunday:
Pipe-mount pilot approved, 6 pods. Field calibration by YardDesk staff with independent meter. District readings displayed as attributed reference points only.
At the top, where it always is: Weight 0.6 (pending pilot).
The YardDesk staff is a kid named Devin Rauch out of the Peoria hub, twenty-four or so, polite, boots so new the tread is still sharp-edged and clean. He's carrying a meter in a hard case with the price sticker still on the lid. He asks her to show him the bracket, and she does. He photographs it from four angles with a tablet. Then he kneels at the pipe, opens the case, and looks into it for a long time.
"They didn't pack buffer," he says.
A meter with no buffer is a stick. You calibrate a pH meter every time, in two bottles of liquid whose pH somebody else has certified. Otherwise all it can tell you is that the water is wet.
She has pH 7 and pH 10 in the truck. They're the half-empty bottles with her initials on the caps in marker and the lot numbers under them. She walks back up the lane to get them. The walk takes six minutes each way in the mud, and she uses it to not say anything.
He calibrates his meter with her buffer, two points, slope 98 percent, which is fine. He puts the probe in the stream next to the pod. 7.61. Pod on the feed: 7.60. Her meter, because she can't not: 7.61.
"So it's independent," Devin says, looking at her bottles sitting on the feed sack. To his credit he laughs first.
"It's two probes that agree," she says. "If my pH 7 lot's off by three hundredths, now we're both wrong the same way. Write down whose buffer. That's the whole job."
He does. She watches him type it on the tablet: BUFFER: TAZEWELL SWCD (J.W.), LOT ON CAP. He reads the lot numbers off her caps and types those too. Nobody told him to.
"Can I get your number," he says, "for if they don't pack it next time?"
"They won't pack it next time either," she says, and gives it to him.
127. 10/11/49 YD PILOT APPROVED, 6 PODS, OWN METER. TECH D. RAUCH (HUMAN, PEORIA) BROUGHT NO BUFFER, USED MINE, LOGGED IT. HIS 7.61 / POD 7.60 / MINE 7.61. WEIGHT 0.6 'PENDING PILOT.' 1.0 H, 22 MI, GRAY.
Gray. The pilot is YardDesk's. The buffer was hers.
That night, kitchen table, the light over it. Card eleven, five new lines since Gary's field.
She reads 126 twice and puts the pencil down.
PAIRED 3 OF 3. Three of what? Storm 6 Schierer was a dash, her choice, the one she had to explain to Kerwin. Storm 7 was a pair, and storm 8 was a pair. Two storms. The third one she counted is Devin's this morning, which wasn't a storm and isn't on that line. She did the same thing on 120 and fixed it last month, after somebody pointed it out. It's the habit of wanting the number to be a little bigger than it is, and it got past her at three in the morning with the heater on her feet.
She doesn't erase it. She draws one line through 3 OF 3, the way the 7.4 got one line, and writes above it, small: STORMS 7, 8 = 2. It's the line Ochoa's pilot will quote, if anybody at YardDesk ever reads a card. It's the line Kerwin will quote, because Kerwin does.
The kitchen smells like apples from the bag on the counter and wet feed sack from the chair. The ticket is open at 0.6, pending a pilot calibrated with her buffer. Gary's statement is folded in his shirt pocket saying he grew a good year of carbon out of mill carbonate, and nobody has told YardDesk, and the pod in his pool is still reading 7.92 into the model every fifteen minutes. Ken's pocket is putting out iron in a dry week. Bauer smells like corn and clay. There's room at the bottom of card eleven for one more line, and card twelve is in the drawer, blank, with the rubber band waiting.
