| Abstract: | Effect of Bentonite as a kind of amendment on soil chemical character and crop growth were studied.The result showed soil active acidity and exchangeable acidity were reduced;CEC,TEB(total exchangeable base) and S % were increased;and the output,height and number of litter were increased too.And effect of treatment ⑤ was best among five treatments and treatment ④ took second place. |
