I do think farming could use a slight upgrade in the kinesthetic department. The active way that we do smithing and chiseling is (in my opinion) the strongest point of the game, and ideally, most mechanics would have that level of detail and interaction. A more anchored animation for tilling and planting might help. I don't think we need to pick the voxels to plant the seeds in, but having something a bit more interesting than right-click-cadabra would go a long way towards making it more interesting.
Also having some visual indicators to plant deficiencies would help. Right now, you have to get your cursor on it to find out if a plant is deprived of a nutrient, suffering heat damage, or lacks a sufficient amount of moisture. Being able to visually see indicators of those without the crosshair info widget would go a long way to driving player interaction, without adding any additional complexity that might be bothersome to a casual player. (Also, scythes should increase seed drop chance).
I'd like farming to be more interesting, but I think it already is, it's just more difficult to engage with due to a lack of easily interpretable information.
