Remembering our past is an essential first step into the future. Building on that philosophy, we summarize two presentations from a 2012 Soil Science Society of America (SSSA) symposium focused on soil management challenges in response to climate change to examine: (i) how the Soil and Water Management and Conservation Division evolved, (ii) how soil management research approaches have changed since the division was founded, and (iii) how division scientists are helping an increasing global population respond to a dynamic and changing climate. Our division roots and much of soil science in general were literally and figuratively grounded in field research. Here, we examine the transition from field‐scale observational to reductionist research approaches, discuss why the latter approach is inadequate for addressing landscape‐scale, cropping system response to climate change, and suggest an alternative soil management research approach for our future. The evolution, challenges, and success of a four‐factor landscape‐scale cropping system study in the U.S. Great Plains is used to illustrate the proposed approach. Recent developments in research programs that promote a more comprehensive systems approach are also provided. We conclude with optimism that by identifying new funding priorities and approaches, SSSA scientists and engineers will be able to help solve several complex and wicked 21st century natural resource problems associated with a dynamic and changing climate and a population of more than nine billion people.
