60 Structural innovations may be relevant also. China has taken the radical step of essentially merging their research and extension systems into a multi-level network of experimental stations, which are staffed to varying degrees by scientists, local educated youth, administrators and farmers. These stations conduct experiments at all levels, from genetics at central stations to field tests at local levels. Extension personnel are not specialists in conveying-information, but are links and participants in the experimental and learning process between and with farmers and scientists.1 In the Puebla Project in Mexico, research and extension personnel, although retaining distinct functions, worked closely together on a day-to-day basis, and this was considered crucial to the project.2 In the U.S., many individuals in land-grant universities and elsewhere have one portion of their salaries and responsibiJities earmarked for research activities and a separate portion specified for extension activities. This also contributes to close linkages between research and extension. Naturally, if extension and research systems emphasize feedback from farmers, there are important implications for agricultural education programs. A closer link between farm and school is needed. Farm workers might be admitted directly into higher education (after appropriate literacy training); students might be given plots of land to work at the beginning of their studies, and grades could take into account general attitudes 1Stavis, "Agricultural Research ..." 2Swanson, "Coordinating Research ...," p. 10.
