Agricultural and industrial products differ in several key ways: 1. Agricultural products are highly perishable and their production depends on seasons, whereas most manufactured products are non-perishable with constant year-round supply. 2. Farm products are bulkier and more difficult to store and transport compared to manufactured goods, which have a more consistent quality and supply. 3. Agricultural output varies in quality and is scattered and irregular, making supply estimation challenging, while industrial production has more uniform quality and supply.
