The report on recent results of soft-QCD with the ATLAS experiment at the LHC is presented. The effect of space-time geometry in the hadronization phase has been studied in the context of Bose-Einstein correlations between charged particles, for determining the size and shape of the source from which particles are emitted and for interpreting the quark confinement effects. Bose-Einstein correlation parameters are investigated in p-p collisions at 0.9 and 7 TeV, up to very high charged-particle

Measurements of the properties of charged particle production are presented from proton-proton collisions at different centre-of-mass energies in the range of 0.9 to 13 TeV and compared to various Monte Carlo event generator models. Furthermore, particle distributions sensitive to the underlying event in proton-proton collisions have been measured and are compared to theoretical models. The production properties of mesons and baryons are presented and compared to predictions.
