Description	Low capacity of acid sandy soils to bind P is a reason for its leaching and runoff. Different soil amendments are used to reduce P leaching. This study was conducted to show the effect of CaCO3, dolomite, gypsum, and CaCl2 on P retention by the Ap horizon of a Spodosol. Phosphorus sorption was studied in a batch experiment at an initial P concentration range 0 to 10 mg L-1. The amendment rate of 0.05 mmol Ca (or Ca+Mg) (and also 0.1 mmol in case of CaCO3 and gypsum) per g of soil was used. The influenceof time after soil amendment (1 h to 1 wk) on P retention was assessed. The adsorption of P was described by Langmuir and Freundlich equations. All amendments except for CaCl2 increased soil pH and P retention by soil. CaCO3 was more effective then dolo mite. The carbonates (CaCO3 and dolomite) were more effective in their interaction with soil. Gypsum increased P retention by itself; upon interaction with soil, its effect was weakened. Sorption of P in soil amended with gypsum is faster than sorption i Low capacity of acid sandy soils to bind P is a reason for its leaching and runoff.
