The error you’re encountering in Farming Simulator 2025 (FS25) with the FS25 Precision Farming mod stems from a divide by zero calculation in the NitrogenMap.lua script. Here’s a breakdown of the likely causes and solutions:

Root Cause

The error occurs in the getFertilizerUsage function (line 1376 of NitrogenMap.lua), which calculates fertilizer/sprayer usage. A division by zero happens when a critical variable used as a divisor (e.g., area, speed, or application rate) is zero or undefined. This is common in farming simulations where calculations depend on dynamic values like:

  • Field area coverage
  • Sprayer width
  • Application rate settings
  • Vehicle speed
  • Map layer data (e.g., weed or nitrogen maps)

Possible Triggers

  1. Zero Application Rate If the slurry spreader’s application rate is set to 0 (e.g., in the vehicle’s UI), the mod might attempt to divide by this value during calculations.
  2. Invalid Work Area Detection The sprayer’s work area might not detect the field properly (e.g., if the tool is not fully over the field or the field is unmarked). This results in an area of 0, causing division by zero.
  3. Missing/Corrupted Map Layers The precision farming mod relies on map layers (e.g., weed maps, nitrogen maps). If these layers are missing, incomplete, or improperly generated, the script might use 0 values for calculations.
  4. Mod Compatibility Issues Conflicts between FS25 Precision Farming and other mods (e.g., custom sprayers, terrain mods) could pass invalid values to the script.
  5. Bug in the Mod’s Script The script might lack safeguards for edge cases (e.g., when starting/stopping the sprayer or when the tool is idle).

Solutions

1. Check Application Rate Settings

  • Ensure the slurry spreader’s application rate is set to a non-zero value in the vehicle’s UI.
  • If using a precision farming map (e.g., weed map), verify it’s properly loaded and active.

2. Validate Field Coverage

  • Make sure the sprayer’s work area is fully covering the field.
  • Check for terrain/field definition errors (e.g., gaps in the field’s ground type).

3. Recreate Map Layers

  • If using custom maps, regenerate the weed, nitrogen, or soil maps via the mod’s in-game tools.
  • Ensure map layers are saved correctly and not corrupted.

4. Update Mods

  • Check for updates to FS25 Precision Farming (version 25.0.1+ might fix this).
  • Ensure all mods are compatible with FS25 and do not conflict with the sprayer’s specialization scripts.

5. Debug the Script (Advanced)

  • Open NitrogenMap.lua and locate line 1376. Add a check to prevent division by zero: lua Copy local divisor = ... -- the value being used as a divisor if divisor == 0 then divisor = 1 -- or handle the error gracefully end
  • This is a temporary fix and may require modding expertise.

If the Issue Persists

  • Report the error to the FS25 Precision Farming mod developers with your log file and steps to reproduce.
  • Disable other mods temporarily to isolate conflicts.

By addressing the zero-value divisor in calculations, you should resolve the error. Let me know if you need further help! 🚜
