  We compute the effect of soft-gluon resummation, at the
next-to-leading-logarithmic level, in the hadroproduction cross-section for
heavy flavours. Applications to top, bottom and charm total cross-sections are
discussed. We find in general that the corrections to the fixed
next-to-leading-order results are larger for larger renormalization scales, and
small, or even negative, for smaller scales. This leads to a significant
reduction of the scale-dependence of the results, for most experimental
configurations of interest.
