The production of neutral strange hadrons is investigated using deep-inelastic scattering events measured with the H1 detector at HERA. The measurements are made in the phase space defined by the negative four-momentum transfer squared of the photon 2<Q2<100GeV2 and the inelasticity 0.1<y<0.6. The Ks and Λ production cross sections and their ratios are determined. Ks production is compared to the production of charged particles in the same region of phase space. The Λ - anti-Λ asymmetry is also measured and found to be consistent with zero. Predictions of leading order Monte Carlo programs are compared to the data.
