Useful measurement techniques for comparing soil structure resulting from conventional cultivation and no-tillage

Different tillages including conventional and minimum tillages were conducted over several yers on a loamy soil, in Gembloux (Belgium). Numerous soil properties were measured to evaluate these tillage practices on soil structure, workability, aeration, biological behaviour, ... with the final aim to establish the mechanisms to improve the yields and the economical returns of a given crop. The paper presents results concerning measurements of dry bulk density, soil structure and microrelief.
