Which method involves not tilling fields for an entire season?

The method that involves not tilling fields for an entire season is summer fallow. This agricultural practice is focused on leaving the land bare and undisturbed for a season, allowing the soil to conserve moisture and replenish its nutrients naturally without the disruption of tillage. It is often used in arid regions to prevent soil erosion and enhance soil health by breaking pest and disease cycles.

Zero-tillage, on the other hand, involves planting crops without disturbing the soil with tillage, allowing for continuous ground cover and reduced erosion, but does not imply leaving the field completely untended for an entire season. Minimum tillage refers to reducing the disturbance of soil through tillage but still involves some degree of soil disruption. Crop rotation is a practice where different crops are grown in succession on the same land to improve soil health and reduce pests but does not involve leaving the field completely unplanted or untilled for a full season. Summer fallow is distinct in its goal of resting the land and maintaining its fertility through non-use of tillage for that period.
