The invention relates to an ecofertilizer including a granular Biochar-Ammonium Phosphate (BAP) fertilizer utilizing by biochar as a renewable support grid. In this study we assessed the impact of two types of uncoated-slow release fertilizer in two types of Biochar-Ammonium Phosphate (BAP1&BAP2) on nitrogen use efficiency (NUE) and N losses in leachate water compared with chemical N fertilizer (ammonium phosphate, AP). Additionally the Surface Morphology of biochar, BAP1 and BAP2 fertilizer were investigated by SEM and FT-IR. SEM and FT-IR confirm the phenomena of impregnation of ammonium phosphate inside the biochar's pores.
