Soil cover of Canada’s cropland and impact from land use and residue management

Liu, J., Huffman, T. 2016. Soil cover of Canada’s cropland and impact from land use and residue management.

Oral presentation.

Abstract

Agricultural activities impact the environment, and agri-environmental indicators have been developed to reveal the status and trends of the impact. Agricultural soils covered by vegetation, crop residues and snow in winter are less susceptible to degradation processes such as erosion, organic matter depletion, structural decline and loss of fertility; therefore, a soil cover indicator has been developed in Canada. This indicator quantifies the effective number of days in a year that a soil is not exposed. This presentation introduces the framework, implementation and assessment of the Canadian soil cover indicator, and analyses the impact of land use and residue management on the indicator.
