    Fertile Grounds are the source for agricultural production and effective nutrients management. We aim at surveying the contribution effect of earthworm casts on physical and chemical soil characteristics (pH, organic matter, electrical conductivity, exchangeable cations) and their impact on morphophysiological parameters of lettuce. Basically, for this operation we have choose three levels of intake (100, 250 and 500g of earthworm casts/pot). The obtained results have shown that the earthworm casts are rich in nutrients such as nitrogen, calcium, potassium and organic matter. Correspondingly, the contribution of earthworm casts has increased the soil content of OM, NTK, K+ and CaCO3. Also, it has a positive effect on chlorophyll, aerial, root biomass and on lettuce growth in general. The results also have indicated that the 500g dose of earthworm casts/pot have been increased the various parameters.
