Abstract Soil stabilization is a method to improve the weakness of fabric peat soil structure which is a result of larger particle size pore. Therefore, the fabric peat soil is solidified using mixture of cement, fly ash and bottom. The present study aimed to investigate a physical simulation of soil column model as a response for affecting the wet and dry seasons and fertilizer on the solidified fabric peat soil. The column mode was investigated by analysis the water leaching micronutrient using atomic adsorption spectroscopy (AAS). The results revealed that the nitrate has the highest concentration (35.55 mg/L) on Run 3 (Fibric, rainwater, solidified peat and fertilizer) at upper area in the dry season. In comparison, potassium (K) recorded the lowest concentrations (1.14 mg / L) on Run 2 (fibric, rainwater and fertilizer) at upper area in the wet season. The highest (22.92 mg/L) and lowest (0.10 mg/L) calcium was recorded on Run 3 and Run 2 with both at upper area in wet season. These findings indicated that the chemical binder used as stabilization soil influenced the nutrient quality especially calcium which is one of the major compound materials in cement.
