cloddish

Like a clod, a person who is foolish, stupid or parochial.

He was a cloddish man, like he'd just fallen off the turnip wagon and hadn't quite woken up yet from his long trip from the country.

Of or pertaining to lumpy soil.

Night-seeding, the tractor's floodlights are blood-red & ovarian - nurturing the cloddish soil, & always the farmer working the wheel, hands gnarled & frostbitten & large.
