It is argued that the soils information we have available to apply to environmental issues has depended on the kinds of questions we have asked in soil science. Four periods are identified in the last 150 yr when we asked different kinds of questions. The last period brings us back to some of the same questions asked in the first period. The characteristics of these periods are discussed to give us a perspective as our thinking is now changing from soils as an input into crop production to include a greater emphasis on soil processes that mediate global changes.
