Well, due to "no source" rule there is not much to say - agriculture is complete crap.
1) Trampling - BS frustrating mechanic only to annoy users without any practical use.
only possible use - crops that interact with user on collusion, damage or heal, but wheat and flower have no such effects and only option to lose your progress.
on my server farm was ruined by people who come to see what crops are, come too close and days (mc days ofc) of work undone. (later on weed spawned on empty crops and finished entire farm)
2) Hydration - wtf hydcation cell ever does? (for user who dont know about source)
Constant clicking will result in empty hydration cell in your hands and nothing else, no visible effect on crops, no visible effect on cell.
3) Nutriens - same problem, especially with crops that require nutriens to grow - you wont be able to ever plant them without source data, also you wont have chance to crossbreed them cos this. (crops with special reqirements actully impossible to grow without source data, there is no clue about it at all)
