One MAJOR problem. You have to charge it with dry fertilizer and grain to get liquid fertilizer, dry fertilizer and seeds as output. Thing is the dry fert in and dry fert out are 1 to 1 ratio, so 2000 in is 2000 out. This means you can NEVER produce any extra dry fertilizer to actually use. That's a massive fail on what would otherwise be a decent mod. Should have used digestate or something similar instead of dry fertilizer.
