Agricultural Revolution
March 8, 1780, Versailles Palace, Cabinet Meeting Room.
The cabinet meeting had been in session for twenty minutes, but no one had spoken a word. Ever since the revised declaration, His Majesty hadn't called on anyone specifically to begin. They were all just exchanging glances, waiting for someone else to break the ice.
The reason the room had grown so frigid was the announcement from the Finance Ministry yesterday afternoon: this year's projected output.
Agricultural production totaled roughly 730 million francs. Commercial production came to about 2.3 billion francs. Projected tax revenue: 530 million francs.
Of course, natural disasters or war could cause yields to plummet. But that was true in normal years as well. Put another way, barring such catastrophes, output wouldn't deviate much from these figures.
"At this rate, someone might just kill themselves. Finance Minister, you start. I'm most curious about yesterday's projected output. Explain it. What in the world happened?"
"Yes, Your Majesty. The Finance Ministry estimates this year's harvest value at a total of 730 million francs. That's a 128% increase over last year's 320 million francs—an unprecedented surge."
"Anyone can see it's unprecedented. What I really want to know is why it jumped 128% in just two months."
"Yes. This is based on calculations by tax inspectors from the National Revenue Service and land surveyors. The tax inspectors attribute it primarily to drastic tax cuts igniting the desire for wealth accumulation, which spiked labor motivation. The land surveyors analyzed it as self-farming households—having hoarded more food than they could eat in the short term during prior shortages—forcing excessive land clearance to plant seeds before it spoiled. Given market conditions, the surveyors' view was deemed slightly more reasonable, leading to the conservative figure of 128%."
128%, huh.
"Less than I expected."
The increase was smaller than anticipated. He'd hoped for over 500%.
"It seems the early reclamation phase, seed instability, overzealous clearing, and lack of proficiency with new techniques are the main culprits. The tax inspectors noted this, offering an optimistic outlook: this year's projection might hover around 128%, but future output could exceed tenfold."
"Not entirely wrong."
A five- or tenfold jump in agricultural production might sound unrealistic, but it wasn't impossible. Even in the modern era, France—factories and all—boasted food self-sufficiency rates of 300-400%, a cheat code of a land. He'd seen satellite images: everything flat except the Swiss border. And in 18th-century France, agriculture was the backbone. Eighty percent of its 25 million people worked the land—fishing and dairy included, but still, at least 15 million farmed. Per land surveyors, about half the national territory was arable. Self-sufficiency rates—his pet project since last year—fluctuated wildly between 150% and 200%.
"Makes those reactionary forces who artificially engineered famines despite 200% self-sufficiency seem all the more impressive..."
"Your Majesty?"
"Nothing. Continue. A tenfold increase in agricultural output is inevitable."
"Your Majesty, per this year's calculations, France's food self-sufficiency stands at 273%. Tenfold would mean 2,730%—I'm not sure that's accurate."
Was it? Wait a second—close call on that miscalculation.
"Finance Minister, I meant tenfold compared to last year. Last year's rate was 120%, wasn't it? Not 2,730%—I said 1,200%."
"Even 1,200% is excessive. Mathematically possible, perhaps... but I doubt it could really happen."
A reasonable skepticism. Even if France ascended to heaven, 1,200% self-sufficiency bordered on delusion. But this was the 18th century. Methods to achieve that "delusion" abounded.
"I'll ask you all: what farming method did our nation use before? Labor Minister, you answer."
"Yes. This humble servant understands French peasants employed the three-field system: dividing land into thirds—one for food wheat, one for fodder barley, and one left fallow to restore fertility."
"That was then."
The three-field system: inefficient to the core. Its origins were lost to history—too ancient for records. Folks claimed it dated to Roman times, a venerable tradition... but to him, it was Stone Age stuff from millennia ago. If he'd been ignorant of agriculture, he might've jury-rigged some basic crop rotation. But he was modern.
"Indeed, Your Majesty. We no longer use outdated methods. Thanks to scholars from across Europe gathered at the Academy since the year before last, we've synthesized the continent's advanced techniques. We extracted the Norfolk system from English émigrés, then experimentally compressed it in the Academy's backyard to optimize combinations. All courtesy of Academy President Lavoisier's new systematic agriculture."
Mixed cropping and four-field rotation.
"The new system."
His 2,000-page gift, that was.
"Wheat from November to May, potatoes from June to early August, buckwheat from mid-August to mid-September, turnips from late September to November. For soil recovery, we broadcast hairy vetch with turnip seeds in early fall—harvested when wheat peaks—and interplant beans in spring. We don't yet know why vetch and beans restore fertility, but the Academy's chemists are analyzing it."
A tactic he'd used to persuade a 95% contrarian AI back when he was obsessed with chatbots.
"Your Majesty, I'm no farmer, but I've heard of Norfolk rotation. It's a four-year cycle, though. A detailed explanation from the Finance Minister would greatly aid the military's forage planning. I humbly request it."
"Supply Officer, your question is valid. Finance Minister, address it."
"Yes, Your Majesty. Norfolk rotation enables sustainable farming without depleting soil. But it's still rotation: turnips-barley-clover-wheat over four years falls short in absolute yield. Its virtue lies in three years of restorative fodder crops feeding livestock for manure, versus one year of human food. Yet even with higher per-unit output, farming once every four years effectively quarters production."
Not exactly a quarter, but inefficient all the same. Sustainable, yes—but short-term productivity was hellish. Low annual yields meant one bad harvest spelled doom. Still, three times stabler than three-field.
"French four-field is different. Root crop potatoes loosen soil and kill weeds. Buckwheat blankets the ground, smothering weeds and binding soil firmly. Turnips root deeply, tilling and clearing remnants. Then wheat thrives in that perfect tilth. Interplanted beans in spring-summer, vetch in fall-winter, ensure fodder self-sufficiency. Academy trials confirm 14-fold yield per acre over three-field."
Potatoes were tubers, not roots—but whatever. Verified, as the minister said. Potatoes till, buckwheat prevents erosion and decays fast for organics. Turnips deep-till, wheat follows. Potatoes, turnips, wheat consume phosphorus, nitrogen, potassium; buckwheat and beans supply them. Vetch provides all: phosphorus, potassium, nitrogen. Labor-intensive? Fertilizer-heavy? Pest-prone? Irrelevant. Public works turned cities into compost hubs via aqueducts. Seized tenant farms from nobility, clergy, and landlords became de facto freeholds. Serf emancipation and feudal abolition flooded fields with labor. Pests? Farmers torched stubble roots every May. Early detection by ample workers—who remembered tenant days—minimized outbreaks.
That was why 1,200% self-sufficiency made sense. France had been reformed for exactly that from the start.
