If the land is only really useful for farming or logging, then no. You'll still get taxed on it, but because the land is relatively low-value it won't be much.

Now, if you're a farmer on the edge of Austin, and the city's growth means your land is getting increasingly valuable due to high housing demand, then your tax will go up, potentially until you're forced to give up farming and sell to developers. That's intentional, it means the land will be used for something more valuable than it's current use.

I think it's worth pointing out that if there's an LVT, whether you own a farm, a parking lot or an empty lot on the edge of Austin, your taxes would go up in any case. There's nothing inherent in an LVT that unfairly penalizes farms.

I'm guessing OP mean it in that a farm needs a lot of land to be viable.
