Definition
Agriculture is the cultivation of land for the production of food, fiber, or other useful crops, together with associated activities carried on by a cultivator in connection with that cultivation. Legal definitions have expanded well beyond simple crop-growing to encompass the full range of farm enterprise.
In statutory and regulatory contexts, agriculture typically includes: (1) the tillage of soil and the planting, raising, and harvesting of crops; (2) the rearing and management of livestock and poultry; (3) dairying and related processing activities conducted on the farm; and (4) ancillary operations that a farmer undertakes in connection with cultivating land, such as the operation of farm machinery, irrigation, and the storage of produce. Whether a given activity qualifies as "agriculture" under a specific statute depends heavily on the purpose and scope of that statute.

Common Language
Modern common usage (Wiktionary): "The art or science of cultivating the ground, including the growing and harvesting of crops, and the rearing and management of livestock."
Historical common usage (Webster's 1913): "The art or science of cultivating the ground, including the harvesting of crops, and the rearing and management of live stock; tillage; husbandry; farming."
The common and legal definitions are broadly aligned in core meaning, but the legal gap is consequential: whether a specific operation qualifies as "agriculture" for purposes of a tax exemption, zoning classification, labor law exclusion, or environmental regulation is a question of statutory construction, not ordinary language. Courts have repeatedly held that the word does not carry a fixed meaning across all legal contexts — what counts as agriculture under a workers' exemption statute may not qualify under a zoning ordinance, and vice versa.

Common Confusion
Agriculture is sometimes used interchangeably with farming, husbandry, and horticulture, but these terms are not always coextensive in legal usage. Horticulture generally refers to the cultivation of gardens, orchards, and nursery stock, and may or may not be subsumed within a statutory definition of agriculture depending on jurisdiction and statutory purpose. Aquaculture — the raising of fish or other aquatic organisms — is frequently excluded from default definitions of agriculture unless expressly included by statute. Researchers working with exemption statutes, labor codes, or zoning ordinances should never assume that a judicial construction of "agriculture" in one statutory context controls in another.

Why It Matters in Research
The legal significance of "agriculture" almost always arises in a definitional contest: Does this activity qualify for an exemption, a preferential tax rate, a zoning classification, or exclusion from a regulatory scheme? The answer turns on the specific statute at issue, not on any universal legal meaning.
Several research traps are common:
First, the statutory scope of agriculture has expanded and contracted over time, particularly under federal labor law. The Fair Labor Standards Act's agricultural exemptions have been litigated extensively, and judicial interpretations of "agriculture" under that statute reflect its specific legislative history — those readings do not travel well to tax or zoning contexts.
Second, historical sources use "agriculture" and "husbandry" almost interchangeably, but modern regulatory schemes often treat them as distinct. A researcher relying on nineteenth-century treatises to interpret a modern agricultural zoning ordinance should verify whether the statutory language has been updated.
Third, the "in connection with" or "incidental to" agricultural activity test appears across many statutory schemes and has generated substantial case law. Whether a farm store, agritourism operation, or on-farm processing facility qualifies as agricultural land use is an active area of litigation in zoning and tax law.
Fourth, the corpus contains significant material on agricultural exemptions in property tax law, which operates on a use-based classification distinct from the ownership or enterprise concepts relevant in labor or environmental law. These should not be conflated.

Historical Dictionary Support
The historical dictionaries largely agree on the core definition — cultivation of the soil for useful crops, combined with the rearing of livestock — but they differ in how broadly they extend the concept.
Bouvier's offers the most expansive formulation, defining agriculture to include "any industry practised by a cultivator of the soil in connection with such cultivation," expressly encompassing breeding, rearing of stock, and dairying. This breadth reflects the nineteenth-century understanding of the integrated farm household economy. Anderson's is somewhat narrower, tying agriculture to "raising cereals and stock" and emphasizing the use-of-the-soil dimension.
Black's Law Dictionary (2nd Ed.) synthesizes the field definition well: "the science or art of cultivating the ground, especially in fields or large areas, including the tillage of the soil, the planting of seeds, the raising and harvesting of crops, and the rearing of live stock." The first edition of Black's adds a practically important gloss — that a person "actually engaged in the science of agriculture" within an exemption statute must derive support from tillage and cultivation, not merely own or manage agricultural land. This distinction between active cultivation and passive ownership recurs in modern exemption litigation.
What the historical dictionaries do not address is the administrative law dimension that now dominates agricultural research: USDA program definitions, EPA regulatory exclusions, and the patchwork of federal statutory definitions (Farm Bill, FLSA, IRC) that govern whether an activity is "agricultural" for any given federal purpose.

Jurisdictional Note
States vary considerably in how they define agriculture for property tax preferential assessment programs, zoning purposes, and right-to-farm statutes. Some states expressly include aquaculture, agritourism, and timber production; others do not. Researchers should not assume that a federal or common-law definition of agriculture controls a state statutory question — consult the specific state code and its judicial construction.
