Low-value crops refer to agricultural products that are generally less profitable and have lower market prices compared to high-value crops. These crops typically require more land and labor to produce relative to the returns they generate, making them less economically viable in terms of transportation and market competition. In the context of agricultural land use, these crops are usually cultivated in areas farther from markets, aligning with the principles outlined in the Von Thunen Model, which examines how distance from market influences agricultural practices.
