You certainly wouldn't against the wishes of the landlord who doesn't want to clean up your mess after you move on. That's a good way to get kicked out.
If it is what the landlord wants, you no doubt would. If you don't there are a 100 other farmers lined up for the land who will.
I think you are vastly overestimating the number of people who want to be farmers.
Well, being a farmer, I have to compete against them and have a good handle on who else wants the land I have been able to rent, and who has taken the land I wished to rent but lost out on. So, no, I don't think so. That doesn't even get into the people who wish they could farm but can't because there are already so many lined up in front of them.
Yeah your land lord is some big conglomerate I’m sure they have very strict rules on what to can/can’t do. But since you don’t care you do the bare minimum as you should
