Modern farm management decisions deal with problems concerning the most profitable size and the best combination of enterprises for a given resource base. These decisions determine a farm's operational and/or organizational efficiency. In addition to selecting a new combination of enterprises, farm managers can make decisions on altering and changing their production practices. New methods allow the same products to be produced, but by a different technique. Situations may arise which also change a farm's resource base. A new method of production may enable a farm operator to continue at a desired output level, while decreasing a production input, thereby increasing efficiency of labor, land or capital.
