  ABSTRACT: Phosphate (PO43-) and Nitrate (NO3-) are two main nutrients that cause water eutrophication. In the other hand, the presence of PO43-and NO3-is needed for plant growth. The aims of this study are to recycleSpent Coffee Ground (SCG) modified with calcium hydroxide for adsorption PO43-and NO3-. The optimum adsorption capacity for PO43-and NO3-is 36.74 mg/L and 20.21 mg/L, respectively. The Freundlich isotherm model was suitable for PO43-and NO3-adsorption. The kinetic model for adsorption was linear using Pseudo-second order. The application of modified SCG after enrichment with PO43-and NO3-for plant growth (Raphanus sativus) showedoptimum growth at a dose of 0.3% with value of germination index was 203%.
