 Well-designed and implemented on-farm research
programs are attractive to policy makers and
infrastructure managers because it is easier for them to
identify with the research in progress. As information
becomes more specific by groups of farms, it becomes
easier to target service development projects and training
to each group of clients. In this way, it becomes easier
to conform research and development to national or
regional policy goals and objectives, such as small farm
development or food sufficiency goals.
