Fertilizer in Honeycomb: The World Beyond: the biomass-plus-horns recipe, where to find strider horns, how to make biomass, and how soil boosts yield.
Why yield is a system, not luck
Once your grow pods are watered, powered and bee-fed, the next lever is yield: how many flowers, fruits and crops each cycle actually gives you. The developers confirmed the lever exists back in Dev Update #9: changing the soil and fertilizing your plants lets you influence the quantity of flowers, fruits and crops you will be able to harvest. Two separate knobs, in other words. Soil is the medium you plant in, fertilizer is the consumable you apply, and both push harvest counts up.
Why should you care on day three of a fresh save? Because yield compounds. Every extra flower from an Allogamy pair is another processing run into hybrid seeds. Every extra fruit is food you did not have to forage. And fertilizer feeds directly into the launch build's strangest little economy: it is crafted from two ingredients that both come from letting nature do its thing, rotting plants and a deer-like alien politely dropping its horns. This guide covers the recipe, both ingredient farms, and the launch-week confusion around biomass that has players scratching their heads.
The fertilizer recipe: biomass plus horns
Player reports from the launch build are consistent on the recipe: fertilizer requires biomass and horns. That is the whole formula, no exotic Pass-zone reagent, which means you can start producing it surprisingly early if you know where the two halves come from. Biomass is the plant half, horns are the animal half, and each has one reliable source and one backup source worth knowing about.
A small honesty note before the details: the game is two days old as this guide goes up, and neither ingredient is documented in any official source with numbers attached. The recipe itself comes from Steam community threads, cross-checked against an official survey log that confirms the horn side of the story. Exact quantities per craft, and whether fertilizer grades or tiers exist, are not yet confirmed. What follows is everything the community has verified so far, flagged as such.
Horns: farming the Imperial Strider
Horns come from striders, the goat- or deer-like ungulates of Sota7. The official Headlands survey log describes the Imperial Strider as graceful and cautious, fleeing swiftly when threatened, and notes that its horns are shed naturally and worth collecting, with real value in crafting recipes. Read that again: shed naturally. You do not fight anything for this. The game has no lethal weapons at all, Hennessy is a pacifist bioengineer, and the strider drops its horns on the ground like a gift.
The practical farming route comes from player reports: strider nests are found near the volcano in the middle of the map, and horns lie on the ground around natural nests. Players also distinguish natural nests from artificial ones, which implies you can eventually build strider housing closer to home, though the ranching depth there is not yet mapped. Approach slowly and give the animals room; they are non-hostile but dislike you getting close right away, and a spooked strider is a strider between you and its nest. Sweep the nest area, grab what is shed, come back later.
Biomass: letting plants rot on purpose
Biomass is the byproduct of decay. According to player reports, it is produced after the usable plant parts reach zero percent, meaning you let picked flowers, fruit and other plant matter fully rot instead of processing or eating them. There is a second, faster source that matters more in practice: unplanting seeds also gives biomass. Given that launch players are drowning in seeds, one report mentions seven stacks of Sweet Tarax seeds, unplanting surplus is the efficient route. Your seed glut is a fertilizer mine.
Here is the launch-week pain point: players who disabled organic decay in the settings report confusion about where biomass comes from, which makes sense once you see the recipe. If rot is off, the slow route to biomass closes, and you are leaning entirely on unplanting seeds. That still works, but it is worth knowing before you flip the toggle that decay is not purely an annoyance; it is half of a crafting pipeline. If you plan to farm fertilizer seriously, either leave organic decay on or stockpile extra seeds to feed the biomass side.
Getting to know the striders
Since horns are half the recipe, the strider is worth a profile. The official Headlands survey log paints the Imperial Strider as an elegant, deer-like ungulate: bi-colored coat running deep chestnut brown to pale cream, white speckles on the shoulders and legs, upward-sweeping horns, a short dark mane and a long tufted tail. It nests within stone formations for cover, and its temperament is graceful and cautious, fleeing swiftly when threatened. The log's handling advice is approach slowly and give it room. A 2023 devlog described striders more casually as very relaxed fellows who like to chill, with the same caveat: do not get too close, they may run away.
None of this involves violence, because the game has none. Hennessy is a pacifist bioengineer, the only injector in the game tranquilizes rather than harms, and the strider's horns are shed naturally, picked up off the ground like fallen fruit. Survey Log #3 adds that the shed horns are worth collecting when found and hold real value in crafting recipes beyond fertilizer, so hoover up every one you see even before you need them. One naming note: player threads refer to the species loosely as the goat-like striders and mention Sage or Imperial variants; whether Sage Strider is a distinct subspecies in the launch build is not yet confirmed.
Soil types you will actually meet
The survey logs quietly document Sota7's soil diversity, and it reads like a preview of the soil-swap system. Sunbeam Lumus grows on loam-type soil in open clearings. Noon Nillow is tied to chalk-rich soil in the Pass. Earth Filoy favors clay-rich uplands and lakesides. Green Naga and Ebony Linter both come from marshes, ponds and wetlands, while Cobalt Sargent is a cave plant. When the developers said changing the soil influences harvest quantity, these habitat tags are almost certainly the vocabulary the mechanic uses.
Until the exact soil-swap UI is mapped, treat the fan-wiki best practices as your interim playbook: keep pods powered and watered, separate parent stock from hybrid output, and do not risk rare Pass specimens early. That last one matters for fertilizer planning too. Run your soil and fertilizer experiments on Valley staples where a failed cycle costs you nothing, record what changed, and only apply the winning combination to the beds that grow your irreplaceable stock. Farming rewards the methodical; the game is a research sim wearing a survival coat.
Soil: the quieter half of the equation
Fertilizer gets the attention because it is a craftable item, but the developers named soil first: changing the soil and fertilizing your plants. Different species also have soil preferences baked into the fiction. The official Valley survey log says Sunbeam Lumus grows on loam-type soil, and Pass-zone Noon Nillow is tied to chalk-rich soil. Whether grow pods let you swap soil media directly in the launch build, and what each soil type costs, is not yet confirmed in any source we have.
What you can act on today: treat soil and fertilizer as a paired upgrade applied to crops you harvest repeatedly, not one-off experiments. A breeding pod running a Solum-family Allogamy pair wants your attention on bloom timing and bee coverage first; a Grow Bed full of staple food crops is where soil swaps and fertilizer applications pay back fastest, because auto-gathering multiplies whatever per-cycle yield you have boosted. Community reports suggest the yield difference is noticeable, but nobody has published numbers yet, so treat any exact percentage you read elsewhere as unverified.
Where better yield actually pays off
Prioritize by what a harvest converts into. Food crops first: Sunbeam Lumus fruit quenches thirst reliably, Earth Filoy from the Pass is described as reliable nutrition, and boosting either cuts your foraging time every single day. Textile crops second: Sweet Tarax stems feed textile crafting, and herbs conveniently return seeds alongside produce, so a fertilized herb bed is nearly self-sustaining. Anything poisonous raw, Green Naga or Ebony Linter, benefits too, since processing yield gates your mid-tier recipes and high-durability gear.
Breeding stock is the third priority, and here the math is subtle. Allogamy produces a hybrid sprout when two same-family flowers share a pod in bloom; more flowers per cycle means more chances and more hybrid material to process into seeds for propagation. Grafting output is similar: a mutated fruit like the Cloudbeam Lumus gets broken into seeds, and a tree that fruits more generously accelerates the whole loop. Fertilizer will not change what a hybrid becomes, that is down to family pairing, but it changes how fast you scale a success into a plantation.
The rot economy and your decay settings
Step back and the launch build has a tidy circular economy hiding in it. Picked plants decay. Fully decayed plant matter becomes biomass. Biomass plus shed horns becomes fertilizer. Fertilizer raises yield. Higher yield means more surplus plant matter, which means more biomass. Hotfix #1 slowed inventory degradation to about half the launch speed, which stretches the loop but does not break it; dropped seeds reportedly never despawn at all, so the unplanting route is untouched by the hotfix.
Decide your decay stance deliberately. Decay on: fresher food pressure, but passive biomass from anything you fail to use in time. Decay off: a calmer fridge, but biomass only from unplanting seeds, so hoard spares instead of scattering them. Either way, keep one chest or corner of the lab as the rot box, a designated pile where surplus goes to die usefully, rather than discovering a stack of mush in your main inventory when you needed the space. It is not glamorous. It is farming.
How yield plays with each plant category
The developers split plants into three categories, crops, trees and herbs, and gave every one its own mechanic. Yield boosting lands differently on each. Herbs are the cleanest case: they mature, you harvest produce and seeds together, and then, at full maturity, the herb dies and disappears from the pod. Fertilizer raises what each of those finite harvests returns, but only if you actually collect in time. A fertilized herb left to over-ripen is a fertilized corpse. Check herb beds daily, or sleep nearby to control the clock.
Trees play the long game. Fruit drops to the ground when the tree is fully grown, and the tree itself persists, hosting your grafting experiments and feeding you every cycle, so yield gains compound season after season. Flowering crops sit in between: their blooms are the raw material of Allogamy, and every extra flower per cycle is another processing run into seeds. If you are deciding where the next dose of fertilizer goes, the rough order of return is herbs first for immediate volume, trees second for compounding, breeding pods last, because there the bottleneck is usually bloom timing and bee coverage rather than raw count.
A fertilizer routine that works
Putting it together into a loop you can run from your second or third day. One: sweep strider nests near the central volcano whenever an expedition passes that way, picking up shed horns; the striders are non-hostile, so this is a walk, not a fight. Two: unplant surplus seeds for biomass on demand, and let genuinely surplus harvest rot in a designated pile if decay is on. Three: craft fertilizer and apply it to your highest-turnover crops first, food and textiles before breeding stock. Four: revisit soil options as they unlock, matching species preferences like loam for Lumus where the build allows.
What we still do not know, said plainly: exact horn drop frequency, biomass yield per rotted item, fertilizer quantities per craft, and whether fertilizer quality tiers exist are all unconfirmed as of September 10, 2026. Community spreadsheets have not appeared yet, and no datamine has surfaced to fill in the numbers. The skeleton above is verified by player reports and one official survey log, and it is enough to double down on the crops that feed you. When the numbers land, this page gets updated. Until then, follow the horns, keep a rot pile going, and treat every single surplus seed in your storage as a down payment on your next bigger harvest.
