In order to improve the management level of soil nutrients in tobacco planting areas in Luoping, and to provide trace fertilizer recommendation. Collection of 210 copies tobacco soil samples to detect. The average contents were as follows, Total N 2.03g/kg, Alkaline hydrolysis N 161.89 mg/kg, total P 1.64 g/kg, available P 40.6 mg/kg, total K 13.7 g/kg, available K 263.19 mg/kg. Total N and Alkaline hydrolysis N were too high, total P and available P were rich, total K was low, available K was rich. It is recommended that proper control of nitrogen fertilizer, to stabilize the amount of phosphate and potash.
