29 CFR 780.145 - The relationship is determined by consideration of all relevant factors.
The character of a practice as a part of the agricultural activity or as a distinct business activity must be determined by examination and evaluation of all the relevant facts and circumstances in the light of the pertinent language and intent of the Act. The result will not depend on any mechanical application of isolated factors or tests. Rather, the total situation will control (Maneja v. Waialua, 349 U.S. 254; Mitchell v. Budd, 350 U.S. 473). Due weight should be given to any available criteria which may indicate whether performance of such a practice may properly be considered an incident to farming within the intent of the Act. Thus, the general relationship, if any, of the practice to farming as evidenced by common understanding, competitive factors, and the prevalence of its performance by farmers (see § 780.146), and similar pertinent matters should be considered. Other factors to be considered in determining whether a practice may be properly regarded as incidental to or in conjunction with the farming operations of a particular farmer or farm include the size of the operations and respective sums invested in land, buildings and equipment for the regular farming operations and in plant and equipment for performance of the practice, the amount of the payroll for each type of work, the number of employees and the amount of time they spend in each of the activities, the extent to which the practice is performed by ordinary farm employees and the amount of interchange of employees between the operations, the amount of revenue derived from each activity, the degree of industrialization involved, and the degree of separation established between the activities. With respect to practices performed on farm products (see § 780.147) and in the consideration of any specific practices (see §§ 780.148-780.158 and 780.205-780.214), there may be special factors in addition to those above mentioned which may aid in the determination.
