[Method] The nutrient contents in 142 soil samples from 7 tobacco planting counties in Fu Zhou city were determined and evaluated. [Result] The organic matter content was on the high side, and most soil was acid soil. The soil had abundant total nitrogen, total phosphorus and total potassium, moderate available nitrogen and available phosphorus, low available potassium, high water soluble chlorine, low soil cation exchange capacity and rich effective zinc, but effective boron was famine. [Conclusion] The meta-acid soil should be conducted with pH adjustment, and rational nitrogen, phosphorus and potassium application.展开更多
