| Prerequisite | Type | Confidence | Evidence level | Note | Sources |
|---|---|---|---|---|---|
| Agriculture (agriculture) | historical_predecessor | 78% | textbook | The plow is an agricultural implement; agriculture is the historical setting and use case rather than a component. |
|
| Basic Woodworking (woodworking_basic) | enabling | 72% | textbook | Early plows were wooden digging-stick or ard-like implements, so woodworking directly enables the earliest forms. |
|
| Animal Husbandry (animal_husbandry) | accelerates | 62% | expert_inference | Draft animals greatly expanded plow use, but hand-pulled or pushed forms mean animal husbandry is not strictly required. |
