A comparative study of 135 fast-growth counties in the 1970s and 115 similar counties in 1980s was conducted to evaluate the impact of urbanization on cropland quality. Results indicated that urbanization did not have a direct effect on improving the quality of cropland bases. However, the results showed that land converted for agricultural use were more productive than those conventional agricultural land.
