"Leaving a field intact for a season"

In Czech, we have a special word for "leaving a field (agricultural) without seeding, resting." I wonder if English has such a word.

Solution 1:

We do have it. The word is fallow.

You'll frequently see it used in the following phrase:

We let the field lie fallow.

Another possibility is uncultivated though that's probably less common.

Solution 2:

In English, we speak of fields lying fallow.

From TheFreeOnlineDictionary:

fallow Plowed but left unseeded during a growing season

Solution 3:

My farming in-laws, in the American mid-west, use the term "set aside ground" to refer to fields that are not planted, or planted with a nutrient restoring crop that is not harvested for profit.
