Characterize the sediment and materials used in the alkaline stabilization. Found that the amount of sediment total phosphorus (Total. Phosphorus) in the soil was 719.9 mg-P/kg is very high compared to the common ground. Phosphorus, soluble (Soluble. Phosphorus) equal to 0.6 mg-P/kg and phosphorus that plants can utilize (Available. Phosphorus) is equal to 643.4 mg-P/kg shows that phosphorus is stored in a form that plants can not use a majority interest.
