| Abstract: | Effects of dolomite powder on nitrogen transformation in vegetable soil under the fertilization condition were studied by means of indoor cultivation. The results showed that, when applying dolomite powder, the content of ammonium nitrogen firstly increased and then decreased; however, the content of nitrate nitrogen gradually increased; following with the in- creased of dolomite powder dosage, the ammonium nitrogen contents decreased but the nitrate nitrogen content increased in vegetable soil. |
