[Method] The research analyzed nutrient changes in tobacco soils in Zhaotong during 2011-2013. [Result] In Zhaotong, pH value of to- bacco soils was increasing; the contents of organic matter and N, P and K contents were in the range suitable for tobacco growth; CI- content was growing in tobacco soils and reached the highest in 2013. [Conclusion] In general, soil nutrients show insignificant differences internannually in Zhaotong.展开更多
