We merge community level data on the availability and quality of publicly provided infrastructure, principally extension, to farm level data containing information on farmer human capital as well as land quantity and quality. By using conununity level measures of availability and quality of extension we avoid problems of endogeneity of farm level measures of extension use. We find positive impacts of farmer education on the diffusion process, in accordance with other studies. We also isolate effects of the quality of regional extension investment as measured by the average experience of technical extension staff.  aBrazil  aInformation technology  aInnovation adoption  aRice  aSoybeans  aAdoção de Inovações  aArroz  aOryza Sativa  aSoja  aTecnologia  aCentro-Oeste1 aBARBOSA, M.
