FS22 ASM Slurry and Digestate Storage v1.0
The ASM Slurry and Digestate Storage solve the issue of space when you need a tank for these items. It has a small footprint and stores 5 million liters of material underground and out of the way.
While this is a simple little mod that is not glamorous, it offers significant benefits on your farm and can be tucked into a small space out of the way until you need it.
