Abstract: In order to guide fertilization scientifically, the authors investigated the effects of different cultivation patterns on the variation trend of field trace elements (Mn, Fe, Cu and Zn) during 15 years. 3974 soil samples were collected from paddy field, maize field and open vegetable topsoil in 2000 and 2014 respectively in suburbs of Shenyang, the results of indoor test showed that the variation range of available Mn, Fe, Cu and Zn was large, which was related to cultivation pattern directly. About 1/3 fields lacked Zn and most of them were rice and maize field. And the deficiency of B was common. The variation of other elements was not significant in this three cultivation patterns.
