Realistic Soil & Fertilizer Mod for Farming Simulator 25 adds meaningful depth to farming without overwhelming complexity. Each field has its own soil health — nitrogen, phosphorus, potassium, organic matter, and pH — that change based on what you grow, what you apply, and the weather. Neglecting your soil will reduce yields, but managing it well makes your farm more efficient.
SOIL NUTRIENTS
Each field independently tracks five values:
- Nitrogen (N) — heavily depleted by most crops, especially corn and canola
- Phosphorus (P) — depletes more slowly, crucial for root crops
- Potassium (K) — lost in large quantities during high-yield harvests, especially potatoes and sugarbeets
- Organic Matter (OM) — enhances long-term fertility; manure, compost, and chopped straw contribute to it
- pH — influences nutrient absorption; lime and gypsum can adjust it
Different crops extract varying amounts of each nutrient. Fallow fields recover slowly on their own. Legumes (soybeans, peas, beans) provide a nitrogen boost in spring. Growing the same crop consecutively increases nutrient extraction.
FERTILIZER TYPES
The mod supports all major fertilizer types used in the base game and popular mods:
- Synthetic:
- Liquid Fertilizer — balanced N/P/K, quick uptake
- Solid Fertilizer — higher phosphorus, standard cost
- Digestate — biogas byproduct, rich in nitrogen and potassium
- UAN28 / UAN32 — liquid nitrogen solutions
- Anhydrous Ammonia — concentrated nitrogen source
- AMS / Urea — dry and liquid nitrogen options
- Starter Fertilizer — high-phosphorus pop-up fertilizer
- MAP / DAP — phosphorus-heavy dry and liquid fertilizers
- Potash — pure potassium source
- Organic:
- Manure — slow-release, increases organic matter
- Slurry — liquid organic, high in potassium
- Compost — excellent organic matter booster
- Biosolids — versatile organic option
- Chicken Manure — concentrated nutrients, boosts organic matter
- Pelletized Manure — processed for easier application
pH Management
- Lime — significantly raises pH
- Liquid Lime — gentler than dry lime
- Gypsum — slightly lowers pH and improves organic matter
Crop Protection
- Insecticide — reduces pest pressure
- Fungicide — reduces disease pressure
Each fertilizer type has realistic nutrient profiles with appropriate application rates in metric or imperial units.
SPRAYER RATE CONTROL
Precisely control fertilizer application per pass:
- Rate Up / Rate Down keys allow on-the-fly adjustments
- 20 rate multipliers from 0.10x to 2.00x in 0.10 increments
- Over-application risks: exceeding 1.25x may cause pH and nitrogen burn; at 1.50x burn is guaranteed
- Auto-Rate mode automatically adjusts based on soil depletion
- Rate settings are vehicle-specific, maintaining your preferences when switching vehicles
YIELD PENALTY
Low nutrient levels reduce yields. Fields require N, P, and K at or above optimal thresholds for full output. Falling below increases penalties, capped depending on crop demands.
PEST, WEED & DISEASE PRESSURE
Fields track weed, pest, and disease pressures independently. Cultivation reduces weed and pest pressure; plowing more effectively reduces pests and diseases. Insecticide and fungicide applications directly lower respective pressures.
HUD
A real-time soil panel displays current nutrient levels:
- 6 preset positions (top right, top left, bottom right, bottom left, center right, or custom)
- Draggable custom position
- 4 color themes: Green, Blue, Amber, Mono
- 3 font sizes
- 5 transparency levels
- Compact mode for smaller screens
- Toggle HUD on/off with a keybinding
- Settings are per-player and do not affect others in multiplayer
A full Soil Report is accessible via keybinding, providing detailed data for the current field.
SOIL MAP OVERLAY
Access a color-coded map overlay while the in-game map is open. Switch between 9 data layers: Nitrogen, Phosphorus, Potassium, pH, Organic Matter, Urgency Score, Weed Pressure, Pest Pressure, and Disease Pressure. Fields are colored based on their current status.
PDA SCREEN
A dedicated PDA page features two tabs:
- Farm Overview — lists all fields with N/P/K/pH/OM data and farm-wide averages
- Treatment Plan — highlights fields needing attention with detailed requirements
SETTINGS
Open with Shift+O. In multiplayer, gameplay settings are admin-controlled; HUD preferences are per-player.
- Toggle systems: Fertility system, nutrient cycles, fertilizer costs, seasonal effects, rain effects, plowing bonus, auto-rate control, notifications
- Difficulty levels: Simple, Realistic, Hardcore
- Units: switch between metric and imperial
PRECISION FARMING COMPATIBILITY
If the official DLC is active, this mod enters read-only mode, observing soil data without conflicts.
MULTIPLAYER
Fully supported. Server manages gameplay settings; each player controls their HUD. Soil data syncs across clients; new players receive full sync automatically.
