Closely following the notion of innovative geographic clusters, this paper examines knowledge flows in the US agriculture industry for evidence of innovative agglomeration. The data indicate that a closer distance between any two agricultural patent origins increases the probability that one cites the other as prior art. Further, subtle inter-regional variations characterize the degree to which proximity advances agricultural innovation. Finally, the results show that older innovations in agriculture proliferate more readily than recently created knowledge.
