The unhomogeneousness of the soil caused uneven plant growth across the field.

The paint on the old fence had faded and peeled unhomogeneously, creating a patchwork of pale and dark wood.

The unhomogeneity of the soil caused unexpected variations in crop growth across the field.

I prefer unhomogenized milk because the cream rises to the top and tastes richer.

The unhomogeneous mixture separated into layers after being left undisturbed.
