Canada's interest in agricultural lands has changed with time from a desire of crop yields at Confederation through to discussions the Senate on adaptation and resilience 2018. Long-term research experiments (LTRs) have been present utilized by federal university researchers provide answers throughout. Here we highlight importance LTRs identifying historical context soil health Canada. We then briefly describe history key results select illustrate wealth information collected North American Project Evaluate Soil Health Measurements cross-country point-in-time sampling these LTRs. discuss LTRs, knowledge gained them, hope that showing distinctive narratives associated each study sites, will be inspired use them address their questions make sound predictions facilitate Canadian agroecosystems climate challenges. Through value generated unique sites inspire not only continued maintenance but also next generation
