 - [Lightning](https://github.com/minetest-mods/lightning): Adds to heavy rain by enabling additional lightning effects
 - [Farming](https://github.com/minetest/minetest_game/tree/master/mods/farming) (as part of MTG) or [Farming Redo](https://forum.minetest.net/viewtopic.php?t=9019): Add farmland and crops to grow food. Farmland wil turn wet during rain effects.
 - [Fire](https://github.com/minetest/minetest_game/tree/master/mods/fire) (as part of MTG): Adds fires that can be caused by lightning strikes and other effects and will be extinguished during rain effects.
+- [Pedology](https://forum.minetest.net/viewtopic.php?f=11&t=9429) Adds a lot of nodes with dynamic wetness and dryness states.
 - [Ambience](https://notabug.org/TenPlus1/ambience): Plays some nice ambient sound effects based on where you are.
 
 For easier installation, you can get a lot of these mods as part of my [Climate Modpack](https://github.com/t-affeldt/climate).
