Nurseries frequently obtain plants growing wild in the woods or fields which are to be further cultivated by the nursery before they are sold by it. Obtaining such plants is a practice which is incidental to farming operations. The activities are therefore within the scope of agriculture if performed by a farmer or on a farm. Thus, employees of the nursery are engaged in agriculture when performing these activities. On the other hand, employees of an independent contractor performing these activities off the farm would not be engaged in agriculture. The transplanting of such wild plants in the nursery is performed “on a farm” and is an agricultural activity whether performed by employees of an independent contractor or by employees of the nursery.
