Effects of farmyard manure treatments on some soil structural parameters such as, aggregate stability, geometric mean weight (GMWD) and mean weight (MWD) diameters, fragmentation (D) and mass (D^sub m^) fractal dimensions, bulk density (BD) and organic C (OC) contents of aggregates were determined in a clay soil. Application of 67 Mg ha^sup -1^ farmyard manure to Vertic Haplustoll soil decreased AS 12.14% compared with the control. Manure treatment increased the proportion of microaggregates in the fractions <1.00 mm in size and decreased the proportion of macroaggregates in the fractions >1.00 mm in size. While OC contents of aggregates increased between 22.8% and 123.4%, BD values decreased between 0.8% and 16.6% with the manure treatment. D and mass D^sub m^ fractal dimensions were increased with decreasing numbers of macroaggregates of the clay soil. GMWD and MWD obtained in the manure treatment were lower than that in the control treatment.
