Under Minnesota law, "agricultural" means farming in all its branches and includes: dairying; field production, cultivation, growing and harvesting of any agricultural or horticultural commodity; and the raising of livestock, bees, fur-bearing animals and poultry. Agriculture also includes cleaning, processing, preserving, loading and transporting to market or storage of farmers' agricultural products as well as repair, maintenance and construction work that is connected to or incidental to agricultural operations.
The Department of Labor and Industry's Labor Standards unit has created a fact sheet to explain overtime and minimum wage regulations for agricultural workers, as well as provide information about minors and migrant workers in agriculture, and Minnesota employment laws for all workers.
