The objective of this work is to obtain measures of the structure of agricultural surface soils, in various regions of Canada, as well as under common management practices; both conventional and conservation tillage will be examined. Ourresearch will focus on soils located at 23 benchmark sites, established in the late 1980's and early 1990's, for which considerable background information have been gather, and on which other studies have since been conducted. Key to this research will be the utilization of high-resolution computed tomography (CT scanning), which can provide detailed information about the internal configuration of the soil components, including the pore network.

这项工作的目标是获得加拿大不同地区农业表层土壤结构的测量，以及在共同管理做法下的测量；将审查常规耕作和保护性耕作。我们的研究将集中在20世纪80年代末S和90年代初S建立的23个基准点的土壤，已经收集了大量的背景信息，此后也进行了其他研究。这项研究的关键将是利用高分辨率计算机断层扫描(CT扫描)，它可以提供土壤成分内部结构的详细信息，包括孔隙网络。
