Worldbuilding? In search of Small Magics?

As far as the magic-end of the worldbuilding I have:

Magic exists.
It’s low-level compared to, like, D&D shit. Hedge-wizard instead of College Mage.

Not everyone has any magic and the few that do are more like:
Can purify/cleanse any water to make it drinkable
Know which direction is north
Can taste the earth and know if it’s too acidic or too basic for cropX
Know when the weather will change
Can start a fire on the first try (cannot call fire, can only ensure the sparks take to the tinder)
Bread always rises/yeast always catches

What else? Small things that fit well with an agrarian society preferred, but really anything could work.
