Abstract: Experiment was carried out at the Pomological Garden of Lithuanian University of Agriculture. The soil type (Calc(ar)i-Endohypogleyic Luvisol). The residual effect of organic mulches on earthworm population was investigated in 2010. The influence of different organic mulches on agrocenosis was investigated in 2004-2009. Scheme of the experiment: Factor A - mulches: 1) no mulching; 2) winter wheat straw; 3) peat; 4) saw dust; 5) grass. Factor B -thickness of mulch layer: 1) 5 cm; 2) 10 cm. The aim of this investigation was to evaluate the residual effect of different organic mulches and different thickness of mulch layer on earthworm population. Effect of organic mulches on earthworm population remainded - in plots which were mulched with grass from grassplots, significantly higher amount and mass of earthworms were established. The smallest amount and mass of earthworms (not significant differences compared with amount and mass of earthworms in unmulched plots) was estimated in plots were peat mulch was used. The significant residual effect of the thickness of mulch layer on the mass of earthworms was established, but not significant - on the amount of earthworms
