This paper attempts to understand the linkages between human capital and input choice in agricultural firms. The hypothesis to be tested is that better educated managers choose different input combinations than managers with a lower educational level. In particular, the hypothesis is that the ratio between non-land and land input increases as education increases. Non-land inputs include fertilizers, machinery services, herbicides, animal stocks and others. An increase in the non-land/land input ratio results in increased output (and costs) per unit of land. Given the fixity of land at the aggregate level, the non-land/land input ratio is an important determinant of total sector output.
