Previous studies have characterised ¿ on large to medium-sized soil aggregates (>4mm diameter); however, little information is available for smaller aggregates (0.99, P<0.0001) between the volumes estimated on rough stones with the PHM and Archimedes methods demonstrates that this technique can be satisfactorily used to estimate the volume and, consequently, the ¿ of small soil aggregates. The results showed an increase in ¿ with decreasing aggregate size. A general trend of increasing ¿ with the degree of soil disturbance by tillage was also observed.2016http://zaguan.unizar.es/record/8430910.1071/SR15163http://zaguan.unizar.es/record/84309oai:zaguan.unizar.es:84309info:eu-repo/grantAgreement/ES/MINECO/BES-2011-076839SOIL RESEARCH 54, 3 (2016), 354-359All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/openAccess
