Agricultural recultivation of sterile dumps involves, besides landscaping works, the mandatory use of mineral and organic fertilization. The paper presents the experimental results obtained for the sunflower crops on a sterile dump in the Mehedinti County, following the application of mineral fertilization with nitrogen and phosphorus and of organic fertilizers such as taurine compost. On a constant background of P60, progressive doses of N40 and N80 were administered, and the compost was applied in doses of 10 t/ha, 20 t/ha, 30 t/ha every 3rd year, 2nd year and annually. Determinations of sunflower crops were targeted at plant height, calatidian diameter, production, MMB and MH, which were analyzed in correlation with the applied mineral fertilization, compost fertilization and compost application time. The findings have shown that on sterile dumps that are poor in organic matter and nutrients, plant cultivation can be achieved with satisfactory results if mineral fertilizers are applied annually, and organic fertilizers are applied annually or at least every 2 years.
