FS25 Density Layer Installer V1.4

QUICK START (no technical knowledge needed)
1. Download FS25_SoilLayerInstaller.exe
2. Close Farming Simulator 25 completely.
3. Doubleclick the .exe — click “Run Installer”.
4. Launch FS25 and load your save. Done.
That’s it. The installer finds your savegame and map automatically,
backs up your map ZIP, and patches everything in one click.
WHAT IT DOES
Patches your active map mod ZIP to add five custom soil densitymap
layers (soilN, soilP, soilK, soilPH, soilOM). Once the layers are
present, FS25_SoilFertilizer can track nutrients at true perpixel
resolution instead of one average value per field.
Without the patch: every pixel inside “Field 3” shares one nitrogen value.
With the patch: each pixel holds its own value, so spraying half a field gives a real left/right split on the map overlay.
REQUIREMENTS
FS25 closed when you run the installer (ZIP files must not be locked)
The map mod ZIP installed in your Mods folder
At least one career save using that map
BACKUP & RESTORE
A backup is created automatically before any changes:
<mapname>.zip.backup_soilinstaller
To undo the patch:
1. Close FS25.
2. Rename the .backup_soilinstaller file back to the original .zip
(remove the .backup_soilinstaller suffix).
3. Launch FS25 — the soil layers are gone.
ALREADY PATCHED?
Rerunning the installer on an alreadypatched map shows “Already Patched”
and does nothing. Safe to run again at any time.
To force a repatch, restore the backup first, then run the installer again.
SUPPORTED MAPS
Any FS25 map mod that:
Ships as a single ZIP in the Mods folder
Has its main i3d file at maps/mapXX.i3d inside the ZIP
Stores terrain data files at maps/data/ inside the ZIP
Tested on: The Pichonniere Valley (FS25_The_Pichonniere_Valley.zip)
NOTES & CAVEATS
FS25_SoilFertilizer must be version 2.2.5.0 or later to detect the layers.
On maps that already ship layers named soilN / soilP / soilK / soilPH / soilOM, the installer detects them and skips — the mod uses them asis.
The blank GRLE files are a safe starting state (all zeros).
FS25_SoilFertilizer fills them in automatically as you spray and harvest.
Multiplayer: all clients must use the patched map ZIP for consistent results.
TROUBLESHOOTING
“No savegame found”
Make sure you have at least one career save in:
Documents/My Games/FarmingSimulator2025/savegame1
“Map ZIP not found”
The map mod name in your savegame does not match any ZIP in your Mods
folder. Confirm the map mod is installed and try again.
Minimap not showing soil colors after load
Wait a few seconds — the overlay rebuilds on a 2second cycle.
“Partial success” result
One or more layers may be missing. Restore the backup, report the
issue (attach the installer log), and do not load FS25 until confirmed.
ADVANCED / CLI USE
If you prefer the command line, the original Python script is also included:
python SoilLayerInstaller.py
Requires Python 3.8 or later. Same logic as the GUI, output in the console.
V1.4.0.0
Adds soilYield as a 9th injected layer, so maps patched with this tool support the Yield map layer in FS25 Soil & Fertilizer.
Already patched an older map? The installer detects the missing layer and adds it on the next patch run, no backup restore needed.
Required mods:
Realistic Soil & Fertilizer

- The installer automatically finds your savegame and map, backs up your map ZIP, and patches it to add custom soil density map layers.
- Launch FS25 and load your save to start using the new soil density layers.

2. **Functionality:**
- The patch adds five custom soil density map layers (soilN, soilP, soilK, soilPH, soilOM) to your map mod ZIP file.
- This allows for true per-pixel resolution tracking of nutrients, providing a more detailed representation of soil characteristics in the game.

3. **Backup & Restore:**
- A backup of the original map ZIP is created before applying the patch for easy restoration.
- To undo the patch, simply rename the backup file back to the original ZIP file and launch FS25.

4. **Advanced Features:**
- The installer supports maps that ship with predefined soil layers and includes support for the soilYield layer in FS25 Soil & Fertilizer.
- For multiplayer, all clients must use the patched map ZIP file for consistent results.

5. **Troubleshooting:**
- Common issues like not finding the savegame or map ZIP are addressed along with solutions.
- Await a few seconds for the minimap to show soil colors after loading.
- In case of partial success, report the issue with the installer log for assistance.

6. **Advanced / CLI Use:**
- For users comfortable with the command line, the original Python script is available for use.
- The updated V1.4.0.0 adds the soilYield layer and automatically detects missing layers for already patched maps.

Overall, the Density Layer Installer V1.4 is a useful tool for enhancing the soil management aspect of Farming Simulator 25. It provides a more detailed and realistic experience for players interested in agriculture simulation. If users encounter any difficulties, the troubleshooting section provides guidance on potential solutions.
