Degraded former gold mining land so that soil fertility is very minimal. Ameliorant mining with an open system causes increased oxidation of sulfurous minerals which reduces nutrient levels and accumulation of heavy metals on the soil surface. This research aims to improve the physical properties of the former gold mining area. This study used a completely randomized design method of 6 treatments with 4 replications. The treatment dose used was 40 tons/ha. The results of this study are that the application of rice husk biochar with manure can provide the best nutrients and growth for sunflower plants.
