Fertilizer Types
The mod recognizes all base-game fertilizer types plus 25+ custom types. Each type has a different nutrient profile applied per 1,000 litres of product.
Custom liquid fertilizers are available as purchasable IBC liquid tanks at in-game shops. Custom dry/solid fertilizers are available as purchasable big bags (1,000–10,000 L) at in-game shops.

|---|---|---|---|---|
| Urea | 0.95 | 0 | 0 | 46-0-0 dry granular |
| AMS | 0.46 | 0 | 0 | 21-0-0-24S ammonium sulphate |
| AN (Ammonium Nitrate) | 0.71 | 0 | 0 | 34-0-0 dry granular; fast-acting nitrate N |
| Fill type | N | P | K | Notes |
|---|---|---|---|---|
| MAP | 0.30 | 1.41 | 0 | 11-52-0; highest P per litre |
| DAP | 0.49 | 1.26 | 0 | 18-46-0; high P with some N |
| Potash | 0 | 0 | 1.63 | 0-0-60 muriate of potash; K only |
| Polifoska 6-20-30 | compound | +4N | +21P | +50K ppm/ha @ 250 kg/ha - compound NPK |
| Fill type | N | P | K | OM | Notes |
|---|---|---|---|---|---|
| Compost | 0.08 | 0.05 | 0.06 | +0.12 | Strong OM builder; low N |
| Biosolids | 0.28 | 0.22 | 0.08 | +0.07 | Municipal organic N+P amendment |

| Pelletized Manure | 0.65 | 0.45 | 0.55 | +0.08 | Dense balanced organic NPK |
| Fill type | pH effect | OM | Notes |
|---|---|---|---|
| Lime (base game) | +0.4 | - | Strongest per-litre pH correction |
| Liquid Lime | +0.3 | - | Slightly weaker per volume than dry |
| Gypsum | −0.10 | +low | Lowers pH; corrects alkaline soil; minor OM gain |
Note
Gypsum lowers pH - use it for alkaline fields (pH > 7.5). Lime raises pH - use it for acidic fields (pH < 6.0).
Applying nitrogen-rich fertilizer above 1.25× the base application rate risks burning the field:
| Rate | Effect |
|---|---|
| > 1.25× | Probabilistic burn: −0.15 pH, −5 N |
| ≥ 1.50× | Guaranteed burn every application: −0.30 pH, −12 N |
Adjust the application rate with the Increase / Decrease Fertilizer Rate actions while in a vehicle (these ship unbound - bind them in Options → Controls → Mods). The Auto-Rate Control feature automatically targets optimal nutrient levels and avoids burn risk.
Three products reduce field health pressure. They do not add nutrients.
| Fill type | Effect | Notes |
|---|---|---|
| Herbicide | Reduces weed pressure | Liquid or spray; also clears weed density on application |
| Insecticide | Reduces pest pressure | Liquid; accepted by all liquid sprayers |
| Fungicide | Reduces disease pressure | Liquid; accepted by all liquid sprayers |
See Field Health System for details on pressure scores, penalties, and recovery rates.
Fertilizer types not listed above are not recognized and will have no effect on soil. If you are using a custom equipment mod that adds new fill types, open a GitHub issue and we can add a profile for it.
