| Abstract | ||
| The effect of chemical and physical properties of the soil on aggregate stability were studied. Fourteen pedons had been selected from Sulaimany and Kirkuk governarate.The correlation (linear regression) between aggregate stability and the chemical and physical properties were applied. The organic carbon contents are significantly correlated with aggregate stability in the surface horizons (R2 =0.89, n=14), while this correlation is weaker with total clay content and free iron oxide (R2=o.29,n=14) and (R2=0.21,n=14) respectivily. The results also indicated that the total calcium carbonate are not correlated with aggregate stability for both surface and subsurface horizons. Generally for subsurface horizons, all the cementing agents are not correlated with aggregate stability. | ||
