This moisture simulation system adds dynamic moisture mechanics to Farming Simulator 25, affecting crop management, harvest timing, storage decisions, yield, and quality. Moisture levels fluctuate across the farm based on terrain elevation, rainfall, snowfall, temperature fluctuations, and day/night cycles. Fields at lower elevations stay wetter, while higher ground dries faster.
Harvested loads receive a quality grade from A (premium) through D (poor), based on moisture content at harvest. Each crop species has unique optimal moisture windows, and grade tables and seasonal moisture projections are available through the integrated in-game interface (Shift+M).
Features
- Terrain-aware field moisture simulation with monthly variation patterns across three distinct environment profiles (Dry/Wet/Normal).
- Sophisticated grass management system featuring progressive tedding mechanics, weather-responsive drying rates, and automatic hay conversion at optimal moisture thresholds. Multiple tedding passes accelerate drying if needed.
- Ground rot: grass and straw piles left exposed accumulate rain exposure over time, triggering progressive volume loss as organic material deteriorates. Hay will revert to grass if it gets too wet.
- Bale rotting: unprotected bales track cumulative rain exposure with initial tolerance periods, escalating decay rates based on exposure history, and limited recovery during dry spells. Wrapping and shelter infrastructure protect bales.
- Purchase the moisture meter hand tool in the store for precise field and pile readings on demand. This can be displayed in the HUD if preferred.
- Customization options for moisture dynamics, tedding efficiency, decay parameters, and interface preferences.
Changelog
2.0.0.9:
- Fixed a game freeze when a hail spell started without a hail strength set, most often seen with winter hail on maps that do not have hail in winter.
- Weather Control OFF now properly uses only the map’s own weather. Previously, extra winter rain and hail could still appear in the forecast after loading a save.
- MacDon grain swaths now follow the weather until they are combined: they dry out in dry weather, get wetter in rain, and slowly rot if left out in the rain too long. Previously, they kept their cut-time moisture and quality forever.
2.0.0.8:
- Hay conversion threshold, the moisture level below which grass becomes hay, is now a setting, with options 4/6/8/10/12%. Defaults to 8%.
- Improved how minimum and maximum weather profile temperatures are applied throughout the day.
- Fixed an issue with moisture not tracking correctly when using Silo Extensions.
V2.0.0.5
- Added support for the Bulk Hall silos added in Highlands Fishing DLC. Moisture and quality will now be tracked for crop stored in these silos, and crop can be dried as normal.
- Fixed an MP lua issue when players join the server.
2.0.0.3:
- Tuned some weather profiles to properly account for how weather like thunder impacts moisture.
- Grain drying is now instigated within the Moisture Menu (
Shift + M) rather than by pressing a key when near the silo. This avoids some issues with some silos while also providing more information. - Durations of weather spells are now scaled based on the number of days per month. This helps planning field work around weather introduced in v2.
- The moisture impact charts can now be hovered with the mouse to show specific yield and quality values for a given moisture level.
- The moisture system now controls weather. Choose a Weather Profile that matches your region in game settings. Many maps have appropriate defaults configured within the mod. Weather includes variability that simulates realistic seasonal patterns, impacting harvest and requiring more planning than before.
- Moisture now impacts yield as well as quality. This is not necessarily more punishing, as crops that are too dry will generally yield badly, while crops that are too wet yield well but have poor quality.
- You can write your own weather profiles if you like, following the guide.
- The moisture calendar has been replaced with a Weather information view showing seasonal forecasts and historical weather data.
- The moisture to quality UI has been replaced with Moisture Impact. This shows the impact of moisture on yield and quality for a given crop.
- Material rotting has generally been eased for both bales and ground piles. Material will take longer to begin to rot and will rot more slowly.
- Fixed an issue with grain drying not starting in multiplayer games.
- Vehicles and silos with crop in them will now show the current grade of the crop in the HUD. Previously, only moisture and quality were shown.
- Added optimisations to how weather impacts ground piles to improve performance for lower-end machines.
- The impact of weather is now scaled based on the number of days per month.
- Drying charges are no longer applied when depositing into your own selling station.
- Existing crop that predates the moisture mod will now be assigned 100% quality and ideal moisture when first interacted with.
- Tightened the rate of crop drying so large volumes of crop do not take forever to dry.
