Farmland

What exactly is the issue here?

Can't you see the problem?

Just throwing in a screenshot and have other people figuring out what the issues is, is not how a bug tracker works. Please provide a detailed description of what the actual issue is. See MC-187478 for example how to write useful bug reports.

Is it really so hard to understand that for some reason, plants like grass are placed on farmland, unlike mushrooms, reeds, etc.? ...
