Here is my suggestion on the easy "steam-roll" to success farming problem fix!
Here are some possibilities to consider:
1:Crop spoilage
2:Terrain/Biome Factor
3:Trample factor (and possibly fences for that)
4:Cageable beefalo that if put corresponding to a farm(s) will fertalize with no need to interact(after building and placing of course)
5:Hostiles/Enemy's could eat crops(Depending on what they are)
6:Wither with out water...so pretty much irrigation
7:Constant need to be tended to because in real life lots of plants will not grow straight up
7:"birth" defects. Ever gotten a weird/ugly looking fruit/veggie? Exactly
8:Pigs will vacate if many of them go missing
I know I won't have much impact but any reader/comment I very much appreciate!
