Why would you want farms in urban settings? We have plenty of farm land as is, in fact if many cities were more densely structured rather than suburban there would be even more farm land.
A land value tax wouldnt tax density it would just tax the value of the land.
This would encourage property density in high value locations like inner cities but wouldn't enforce it.
In terms of farmland it would just mean that farmers rent the land from the government rather than, say, blackrock or bill gates (two of the biggest owners of farmland right now).
This would not affect food prices by much it would just mean that when you buy food from those farms, instead of ~15% of the price flowing into bill gates' pocket it would flow into government coffers. Bad luck Bill Gates. Bad luck Blackrock.

I wasn’t responding to an LVT suggestion, but a suggestion of taxes that would be based on density of use and go up for lower density. I quoted the suggestion in my response. LVT is a whole different thing.
The value in LTV would be influenced by density. If every parcel around a plot of land is dense the total value would be higher. So tax the land at the average density of surrounding parcels and allow for unlimited density. That would incentivize density and development where it is needed and prevent a single hold out from inefficiently blocking development.
