FS25_SoilFertilizer Wiki

Realistic Soil & Fertilizer adds per-field nutrient management to Farming Simulator 25. Every field on the map tracks Nitrogen (N), Phosphorus (P), Potassium (K), Organic Matter (OM), and pH independently. Crops deplete nutrients at harvest; fertilizer, manure, and lime restore them. Rain leaches nutrients, seasons shift nitrogen, and neglected fields slowly recover on their own.

Warning

Not compatible with Precision Farming (FS25_precisionFarming). When Precision Farming is detected as active, this mod automatically disables itself at startup to prevent data corruption. Disable PF in the mod manager to use this mod instead. If PF is installed but disabled in the mod manager, this mod will run normally.

Quick facts

  • Current version: 2.2.5.0
  • Multiplayer: fully supported — server-authoritative settings, admin-only changes
  • Dedicated server: fully supported — HUD and GUI are disabled server-side, simulation runs normally; minimap heatmap layer is client-only and automatically disabled on dedicated servers
  • Precision Farming: NOT compatible — the mod auto-detects PF and disables itself when PF is active
  • Multifruit maps: supported — unknown crops use a balanced fallback extraction rate
  • Field Health System: weed, pest, and disease pressure tracked per field — apply herbicide, insecticide, or fungicide to reduce
  • Soil Compaction: vehicles ≥ 8 t compact soil (0–100%), capped at 20% nutrient penalty; subsoiler reduces by 15% per pass — see Soil Compaction
  • Coverage Tracking: sprayer tracks per-cell coverage; fully-treated notification requires ≥ 70% field coverage
  • PDA Soil Page: press Shift+P in-game to open the PDA with Farm Overview and Treatment Plan tabs
  • Soil Map overlay: press ESC → Map and use the sidebar to toggle and cycle overlay layers (10 layers including Compaction)
  • Save compatibility: soil data saved to soilData.xml in your savegame folder
