摘要

加拿大对农业用地的兴趣随着时间的推移而改变,从联邦对作物产量的渴望,到2018年参议院对适应性和弹性的讨论。长期研究实验(ltr)一直存在,并被联邦和大学研究人员利用,以提供贯穿始终的答案。在这里,我们通过确定长期研究中心和加拿大土壤健康研究的历史背景来强调长期研究中心的重要性。然后,我们简要地描述了选定ltr的历史和关键结果,并说明了从北美评估土壤健康测量项目中收集的丰富信息,该项目从这些ltr中进行跨国时间点土壤采样。我们讨论ltr,以及从中获得的知识,希望通过展示与每个研究地点相关的独特叙述,研究人员将受到启发,使用它们来解决他们的研究问题,并做出合理的预测,以促进加拿大农业生态系统适应气候挑战。我们希望,透过认识这些独特的土地注册处所产生的价值,这些地点的重要性不仅会启发他们继续维修,也会启发下一代的土地注册处。

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

期刊介绍: The Canadian Journal of Soil Science is an international peer-reviewed journal published in cooperation with the Canadian Society of Soil Science. The journal publishes original research on the use, management, structure and development of soils and draws from the disciplines of soil science, agrometeorology, ecology, agricultural engineering, environmental science, hydrology, forestry, geology, geography and climatology. Research is published in a number of topic sections including: agrometeorology; ecology, biological processes and plant interactions; composition and chemical processes; physical processes and interfaces; genesis, landscape processes and relationships; contamination and environmental stewardship; and management for agricultural, forestry and urban uses.
