Basic Agriculture

Lore & Background

In the geological cross-section that serves as the game's world, soil layers are not merely decorative strata—they are the single most valuable real estate a dupes' settlement can claim. Before Basic Agriculture is researched, those dirt tiles are just obstacles to dig through. Afterward, every patch of loose, waterable soil becomes a potential field, and the dupes' relationship with the ground shifts from "get me out of here" to "get me to that plot."

The research itself is modest in scope: it teaches the basic biological cycle of seed, water, growth, and harvest. No exotic machinery is required, no pressurized hydroponic bays, no nutrient paste vats. A dupes simply needs a seed (gathered from the world's native flora or salvaged from the environment), a tilled or naturally loose soil tile, and a steady supply of liquid water. The plant cycles through visible growth stages—sprout, mid-growth, mature—and a dupes can then harvest the crop for food or for additional seeds to replant. It is, in the grand scheme of a colony struggling with oxygen, temperature, and pressure, almost deceptively simple.

Fans often describe unlocking Basic Agriculture as the emotional turning point of a run. The early game is a gauntlet of survival—keep the dupes breathing, keep them warm, keep them from suffocating in a CO₂ pocket. The moment the first seed goes into the ground and a dupes dutifully waters it, the colony starts to feel less like a lifeboat and more like a home. The little green sprout against the brown dirt is, for many players, the image that makes the rest of the build worth it.

In Their Own Story

The soil was cold and packed tight, the way all the dirt in this layer was. Mara knelt in the narrow trench she'd dug three tiles wide, pressing her thumb into the loose topsoil she'd raked free. Behind her, the colony hummed—pumps gurgling, a heat vent ticking, the low thrum of the oxygen generator that kept them from slowly suffocating in the dark.

She pulled the seed from her pocket. Small, dry, unremarkable. She'd pried it from a withered vine back in the upper biome, back when the air still tasted like rust and the light was just a pale smear through the rock above.

"Water's in the tank, third shelf," called Tomas from the corridor, not looking up from the wiring he was stripping.

Mara nodded. She made a little furrow with her fingers, dropped the seed in, patted the soil flat. Then she stood, brushed the dirt from her knees, and walked back toward the warm glow of the generator.

Three days later, a green thread poked up through the brown. Tomas was the first to notice. He stood very still for a long time, watching it, before he said, quietly, "We're actually going to eat something we grew."

Nobody laughed. Nobody needed to.

Reader's Guide

Basic Agriculture is a single Tier 1 research entry rather than a bundle of machine blueprints. Below is what it provides and how it fits into the broader agriculture system.

**Tier 1 – Basic Agriculture** Unlocks: The ability to plant seeds in soil tiles and grow crops through their full life cycle. Function: A dupes places a seed into a loose soil tile, waters it, and the plant progresses through visible growth stages (sprout → mid → mature). At maturity the dupes harvest the crop, which can be consumed as food or broken down for additional seeds. No dedicated machine is built; the "machine" here is the dupes' own labor combined with the soil tile itself.

**Practical notes for the guide reader:** - You need a source of seeds (native flora, gathered items, or later, harvested crops) before this research is useful. - Soil must be in a tile that can receive liquid water; sealed or compressed dirt won't work. - Dupes will automatically tend planted seeds once the research is complete—watering, harvesting—so you don't have to micromanage every sprout. - This tech is the prerequisite for any further food-production research (improved crops, hydroponics, or nutrient-processing machines in later tiers). - Plan your farm location with airflow and temperature in mind; a crop in a CO₂ pocket or a freezing pocket will stall or die, and dupes will still walk over to water it.

In short: one research, one new verb for your dupes ("plant"), and a permanent shift from foraging to farming.

Did You Know?

• Basic Agriculture does not require you to build a dedicated farming machine—the dupes simply use their hands and a soil tile, making it one of the few 'techs' in ONI that unlock a labor action rather than a constructible
• Crops grown under Basic Agriculture can be harvested for additional seeds, meaning a single found seed can, in theory, sustain an entire colony's food supply indefinitely if you manage the replanting cycle.
• The research sits at the very base of the agriculture branch, so it is a hard prerequisite for every later food-related tech; skip it and your dupes are stuck eating whatever the planet's biomes happen to provide.
• Because planting only requires a soil tile and water, early-game players can set up a tiny one-tile 'farm' in a corner of their base without any structural build, making it one of the cheapest quality-of-life upgrades av
