RELATIONS ENTRE LA TENEUR EN MATIÈRE ORGANIQUE ET LA MASSE VOLUMIQUE APPARENTE DU SOL

Abstract
As a part of a study on soil compaction, measurements of soil bulk density were taken three times during the season at five sites and three depths. Strong negative correlations were obtained between soil organic matter content and (1) soil bulk density and, (2) the increase in bulk density during the season. Key words: Bulk density, compaction, organic matter
