Natural Fertilizer
Natural Fertilizer introduces a simple but immersive manure system to Vintage Story.
Domesticated animals now periodically defecate, leaving droppings in the world that can be collected and processed into fertilizer.
Features & Mechanics
-
Animal Manure: Domesticated animals naturally produce dung over time, when fed.
-
Dung Piles: Droppings accumulate in stages and can be combined into larger piles.
-
Fertilizer Use: Manure piles can be composted directly on the ground, or in barrels, to produce fertilizer that can improve farmland soil for better fertility.
-
Smart Placement: The system avoids overwriting important blocks like chicken eggs, nests, or other droppings.
-
Configurable Rules: Forbidden overwrite targets are configurable via JSON for modpack balance.
-
Immersive Gameplay: Droppings appear naturally in barns, pastures and pens, encouraging players to manage livestock waste as a resource.
What this mod currently changes/adds:
- Animals fed from troughs or food thrown on the ground, will produce droppings after a random time.
- Manure can be processed into fertilizer in two immersive methods: ground piles or fermented in a barrel.
- Fertilizers can be used on tilled farmland, just like any other fertilizer in the game.
Animals that currently can produce manure:
-
- Pigs
- Sheep
- Chickens
- All variants of Hares
- All variants of Goats
Fertilizer properties:
| Fertilizer type: | N | P | K |
| Weak fertilizer | 15% | 4% | 4% |
| Medium fertilizer | 25% | 6% | 6% |
Compatibility:
Roadmap:
-
- Compatibility with various creature mods.
- Add more configuration options to easier adapt use and compatibility. (WIP)
- Add configurations for each animals chance to defecate and amount of manure. (WIP)
- Manure piles left on the ground for long periods of time, without mixing with grass to start fermentation, will transit to a low value fertilizer.
- Weather effects processing time for open air compost piles.
- Flies buzz over piles of manure and storage that contain manure.
- Wheelbarrow for transporting large amounts of manure.
- Add proper compost bin, to avert from using barrels.
- Variations in fertilizers, depending on what type of manure is used, and what is mixed with the manure.
- Proper handbook guide with explanations of mechanics and uses of it's content.

Sometimes, scooping up chicken droppings give you no dung at all
That is rng playing you tricks, as the droprate is low for just a single piece to actually give you something to collect.
For chicken droppings it's best to let it accumulate a bit, for guaranteed drop.
On that note, I am working on separating the various droppings into their own type of manure, to make mixed fertilizers.
Still a wip, and no idea when I'll get time to finish it at this moment..
I knew it had to be RNG based! That certainly clears it up.
Could you make the dung throwable in the same way a pebble is throwable?
I'll consider it 😅
I second this, lets me roleplay as a toxic dark souls player who throws dung at foes, lmao.
This mod is THE SHIT! I was raised in the '90s, IYKYK
Sealing a barrel of mixed manure slurry causes an unhandled exception and DC when installed alongside the xskills fork. There's no actual problem with the barrel, it seals properly and works. You just DC when sealing it.
Can confirm this happens.
Can confirm as well
Oh dear, still no update yet? Has anyone found out a way to remedy this?
Anyone else having issue when trying to seal manure in a barrel with the correct amount of water, its not working for me?
Did you also add the needed grass?
I feel like iv'e tried every combo I can think of but the poop...the poop outwitts me.
I have tried picking up manure with a bucket so it can be used as a liquid but wont let me?
The ratios are 1L water 5 manure
Start with the water. 10L water, then add 50 manure.
This will produce 50L of slurry.
Then add a full stack of grass to complete the mixture, and seal the barrel for it to ferment.
As for the manure, you can also stack them on the ground in piles of 32, and add 64 grass till it says "Fermenting".
OOh could you add compatibility with Draconis, Monoceros, and Pegasus? Imagine... Dragon poops
Dragon poops- while it would be the normal poo tones, the first image that came to mind was the neopets rainbow dung.

Amazing, would be so cool if even wild animals could poop sometime and we can just run across poop ! For imersion !!!
You might be surprised to sometimes find wild poop already 😉
We love this mod! One suggestion - would it be possible to make a manure shovel that only works on poop? With our traits I pick up dirt in just a couple milliseconds, so I end up digging up the dirt instead of the poop if I miss. Just a little suggestion! <3
We need... a POOPER SCOOPER!
Thank you for the kind words, and idea for a poop scoop 😆
I will see what I can come up with.
I think that adding a function mode to a shovel would be better for the overall functionality of the game system and item management. Scythe already has such option, why not expand it?
Oooh, great idea!
Could also put some code on it that the tool in that mode prioritizes poop instead of whatever else is on the tile, so you don't have to fight to get the critters out of the way to scoop it up.
My buddies make fun of me for using the poop mod but this is genuinly one of my favorite mods. It makes acquiring nitrogen fertilizer so much easier and adds additional depth to animal husbandry as a mechanic. Genuinly one of my favorite farming mods.
Thank you for the kind words, I'm happy you find it useful 😊
Hey, ah...how do you make the manure piles for fermenting? I've been piling up the stuff and it's not doing anything. It says they're made of wood, but...er. There's no recipe.
Do I keep piling it in one spot until it does something? Otherwise everything else seems to work.
Pile it in one spot on the ground till it reaches max (32 manure) and then add 64 grass. It will change texture as you add the grass, and should say fermenting when you have added enough grass.
Or, mix it in a barrel with water, then add grass and close the lid to start fermentation. The ratio is in the handbook.
Will add a more in-depth handbook entry in the next release.
Oh! Well, that makes sense. And here I've been a bit of a derp on that.
In that case, I'll try precisely that. Mn. Thank you, this is greatly appreciated, and I can share the info with the server now since...ah, they were a little confused too.
Love the mod! :D
I have one suggestion - would it be possible to add a fertilizer bag, which would store the fertilizer items and spread it on 3x3 space? It would be a really great addition :)
UN MOD NECESARIO VANILLA, sin duda un muy muy buen mod, le doy mis mas sinceras adulaciones al creador.
Thank you soo much for your kind words 😊
This is a shitty mod in all the best ways :D The roadmap already contains almost everything I can suggest.
Maybe one day, menure could be used to waddle and daub, as that was a thing.
Maybe if manure from different animals gets different stats, it would be cool if pig manure, uncollected, slowly turns the pig sty into a muddy mess?
Thank you!
Wattle and daub... hmm, now that IS a thing that is still done. I'll contemplate it, no promises.
As for various stats on the manure, that is a thing I have planned.
I just need to find the time..
No rush :D its already a great mod! and we (me and the lads) appriciate the good work
Hooray, manure!
Enjoy! 😆
I get two errors (Patch 0 and 1) in the medieval expansion patch entity-patches.json, it seems to be calling on Medieval Expansion Patch's Aurochs male and female json files that the built in compatibility isn't able to find. So far it hasn't caused a crash or lag or anything like that, just a bug testing FYI lol
I'll look into that, thank you for the heads up.
This also is making the mod not work with Aurochs at all (probably obvious).
This issue should now be fixed.
The Aurochs are yet again happily poopin 😊
Legend <3 love your mods
Thank you 😊
Eeewww poooo. Thanks for update Ape hehe xD
😆
You're welcome!
pliss 1.22
Working on it.
gracias por tu trabajo moder!!! \(o^o)/
I have opened a PR in your repo that updates a lot of the code to the 1.22 changes. Please review it when you can.
Thank you. I will take a look at this soon.
slimy_wizard , Averixus
I'll start work on this soon!
omg thank you so much! excited to get back to shoveling chicken poo for my farm lol
i love this mod so much. i really hope it gets updated to 1.22.1 version soon!
I love this mod! Any plans to update to 1.22? I tried out the latest release but it crashes instantly on loading a world
Granted, I have a heavily modded game, but the latest version has simply stopped working. Animals don't poop. It's probably a mod conflict. When I drop back to 1.2 the mod works again and animals be poopin.
The droppings of birds and other animals differ significantly from each other in terms of their use in agriculture. This includes their nutrient content. Are there any plans to differentiate between them?
The second point is that at a certain stage, manure is warmer than the surrounding air, and this property is sometimes used in agriculture. However, too much manure can ‘burn’ plant roots. Are there any plans to add this mechanic? Well, plants in fertilised soil can withstand temperatures several degrees lower, but adding too much will damage the plants.
I completely updated the Russian translation, as it was incomplete.
i have created a mod that allows players to create custom burnable fules "briquettes" with dynamic burn rates and duratoins based on the input ingredients.
in real life people do make briquettes out of manure which is why i am reaching out to you to get your opinion and see what you would like to do for mod compat if any at all
i currently have 3 optoins for making our mods compatible
optoin 1
if you add a burnable property to your manure items my mod will simply detect it as a valid recipe ingredient and pull burn properties dynamically (my mod allready works with modded fuels)
this gives you full controll to adjust and update if needed, add new items while maintaining mod compatability with no extra effort on my side.
optoin 2
i can add a burnable porperty to your items when your mod is detected. this means "only if my mod and your mod are installed at the same time, your items will have burnable properties"
this option means i would need to maintain and update the burnable properties from within my own mod any time you update (which is less desirable)
optoin 3
i can adjust my deafult config file file, which will asign "sudo burn temp and duratoin" values. this would not make your items burnable in the traditional sense, but for the purpose of briquette making, it will become a valid ingredient.
people can allreayd do this themselves with my config. for mod packs it is not a big deal. but having some deafult values filled in, could be nice.
at any case, and at the very least, i would like to get your thoughts on burn time and duration for your items.
Can you add a feature to the dung to be able to throw it to prank my friends, it would be so funny.
thanks for the tip Greenmind x)
Gingertea I've been using it with no issues in 1.21.6
One thing I'd recommend is to place cobblestone down under your animals. I didn't initially and ended up digging up blocks which is annoying. If I knew more about mods I'd make a pitchfork tool that works like the scythe but for poo.
1.21.6 ?
I love this mod, but i have an issue. It says its compatible with the FOTSA Bovinae mod yet my cattle have yet to poop. is it dependent on how much they eat? Because my pigs and ducks work, but not the cows
My question right now is: Do the droppings create entity markers on the minimap/world map when using the Mob Radar mod? Cuz that would be a bit annoying.
Omg I love this 🤣
... it poop
... it smells
... it reeks
... the flies are buzzing
i`m not being able to catch it with the shover, it just dissapear quickly after i use it on
I would love to use this, but can't figure out how to mix grass with manure piles on the ground, or how to remove manure slurry from barrels. Could you please add a description for dummies, on how to do those things?
Could you please make this compatible with https://mods.vintagestory.at/saltpeterproduction ?
Great mod.
Is there any way you could add this to wild animals too? I was literally just thinking a mod like this would work perfectly with the Footsteps mod to introduce more immersive hunting. It would be especially useful if you could tell if it's fresh or old droppings.
Hydromancerx
Added to the list for next update 👍
Please patch for Lichen Continued. They have a White Stag and Gemsbok.
Thanks!
You really need to add the ability to pick it up and hurl it like a snowball.
DejFidOFF
Yes! That will come in the next update 😀

Hi. Should you add compatibiliti with aurochs from medieval expansion please?
KonradDark
It should be in the same folder as the other log files. It can also be in the "Archives" folder, if you have restarted the game after the crash happened. If you can't find it, it's ok.
xXx_Ape_xXx
how to find client-crash log? Because I don't see any, maybe because my client didn't crashed, it just kicked to main menu.
KonradDark
Interesting.. sounds like some other mod might be interfering with the barrels, all this mod does is add three barrel recipes, and I've not seen this issue on the server I play on.
Please use the issue tracker located above the pictures, and post your client-main, client-debug and client-crash logs there, so I can see if there's anything that might come from this mod.
Hey on one server I'm playing we have this mod it's fun to use but idk why but everytime I wanna close the barrel to make medium fertilizer it say it threw an exception on a server and kick me out of it, when I relog I can close the barrel normally... until I wanna close another barrel.
Moltenhead
I gotcha! Will be added in the next update.
Hi there! That's a very cool idea and it brings even more cooperation between professions within multiplayer.
One more compatibility request : medievalexpansionpatch mod, I think this one is pretty common. (at least for me 😇)
I'm downloading now!
You should add the Unicorn mod and give them rainbow poo!
Also please support ...
- Haz's Monitor Lizards
- Hieronymus's Reptiles Collection
- Draconis
- Archosaur
Thanks!
This SHIT is great
xXx_Ape_xXx sick, great mod btw.
Diarko
Added!
animatiV
Added!
Great mod idea - should have been vanilla! It would be helpful to have recipes for use here until proper handbook pages are complete. Thanks!
animatiV
Yes, that's a work in progress already. Some are easy to add, others (Equus) are not, so no promise on when this will be added yet.
Nice mod. Will you be adding support for other mods that add animals? For example, Critters Pack, More Animals, Draconis, Equus, the FotSA series, etc.?
tofiktofik
Interesting idea, I will do some research and see what I can come up with. Thnx for the suggestions!
Beedy
Added.
A very promising mod, I'll definetly try it.
However, one important thing is missing in the mod description here: What nutrient type does this mod's fertilizer provide? Nitrogen (N), Phosphorus (P), Potassium (K), or all equally?
jak już takie coś dodałeś to świetny pomysł na rozwinięcie tego projektu w produkcje nawozów NPK np. 8-20-30 , 20-20-20 , 5-15-30 , 12,11,18 , 0-52-34 , 0-20-20 , 0-40-40 itp. tylko teraz dobrze dobrać produkcje tego i będzie wypas
LivCi
Currently, no, but I will consider it, if I find a good balance to not make it OP compared to regular compost.
Can this fertilizer be used as a compost substitute for terra preta?
Can you add compatibility with Equus Wild Horses mod
Excellent idea for a mod 👍
Yes this is something I was looking for for ages! I was about to go make it myself! Great work!
This is your crappiest mod yet! ^_^
Looks good!
having manure in the game opens up the possibility of creating saltpeter in a realistic way. That would make for a great mod too
Love this! Will test on my server asap
Tego brakowało mi w moich hodowlach. Dzięki
If there was a best mod of the month right now, you would deserve it, this is a truly unique idea!
amazing idea, that is one thing the animals needed!
SaturnSky
😂
💩
Something about this mod stinks...
Oo, this shit is sick.
