Alchemy Factory Fertilizer Blueprint: Automate Early

Quick answer

The documented Alchemy Factory fertilizer blueprint is a community-designed module that automates fertilizer from plant ash (sage) and quicklime (stone). It outputs about 20 fertilizer per minute and, after feeding itself, supports roughly three nurseries. It requires at least one fuel-efficiency upgrade to self-fuel without jamming.

The module's two input chains

The design combines two sourced inputs. Plant ash comes only from sage, burned in a crucible. Quicklime powder comes from quicklime, which comes from stone: the quicklime step runs in a grinder (about 9 seconds) and the quicklime-powder step in a crucible (also about 9 seconds), giving a consistent build speed.

Both chains are steady, so the module's output is predictable — the key property for a reusable blueprint.

The output and the nursery ratio

Observed builds produce about 20 fertilizer per minute from three crucibles running plant ash at roughly 6.7 per minute each. A nursery consumes about 5 per minute (fertilizer used every 12 seconds), so one module supports four consumers minus itself — three nurseries in practice.

That 1:3 ratio is the planning rule when you scale farming: add one fertilizer module per three nurseries.

The fuel-efficiency requirement

The trap in this blueprint is the self-fuel loop. If the module burns wood into charcoal powder to feed itself, it will stutter and spill output unless you have at least one fuel-efficiency upgrade — preferably two. Without it, the wood-to-charcoal loop does not make enough fuel to sustain the build.

The same playthroughs advise keeping fertilizer production independent of fuel production: feed leftover planks from advanced fertilizer into relics or trash rather than into coke powder, so a fuel shortage never breaks farming.

Why it is called the key early design

Fertilizer underpins the entire farming side, and manual fertilizing eats the limited time each day. Automating it early removes a recurring manual task and frees your day for planning. The design is also a stepping stone: its stable base supports the later glass → blender → vitality potion path.

What is still unconfirmed

Exact machine counts, belt routing, and footprints for a published fertilizer blueprint, plus advanced-fertilizer bonus values, are 待确认. The chain, 20-per-minute output, and 12-second use rate come from community footage and should be re-checked against your own build.
