Abstract The OECD Guideline 106 was selected as reference method, in purpose of investigating the effect of nitrogen-containing and phosphorus-containing fertilizers on adsorption of OTC in cinnamon soil. In addition, ammonium chloride, urea, calcium nitrate and triple superphosphate were employed as treatment factors. The isothermal adsorption test showed that data could be fitted very well (PNH4Cl>CK>Ca(H2PO4)2>CO(NH2)2. In terms of adsorption rate and distribution coefficient, CO(NH2)2 gave rise to the most significant influence which decreased by 2.43%, 13.19% averagely, and Ca(H2PO4)2 led to the least significant influence which lowered by 1.75%, 9.59%.
