  5. Our aim is to provide reference data for the mechanism of the effects of ree on crops and the safety evaluation of re used in agriculture. 1. in soil culture experiment, re applications with appropriate dose in dry condition increased the contents of soil available n, whose no - effect value were 505mg / kg at eighth week, whereas higher levels of re had negative effects, re applications with both appropriate and higher dose in inundated condition reduced the contents of soil nh / - n and hydrolysable n. re treatment concentrations showed significant positive correlation with the contents of soil exchangeable re. and significant negative correlation with the contents of soil available p and soil ph value. there was no significant effects of re on soil exchangeable cations, but applications of re increased the contents of soil water soluble cations, especially that of ca2 * and mg2 +
