Abstract：Shandong Province is the two-cropping area of potato in the Central Plain, and its yield and benefit rank the first in China.In order to realize reasonable nutrient management, high yield and high benefit of potato production, the soil nutrient status of main potato producing areas in Shandong Province was investi-gated.The fertilizer use efficiency and its yield increasing effect were also analyzed under the conditions of fer-tilization and no fertilization.The results showed that under the condition of long-term fertilization with large amount, Tengzhou had the highest soil fertility, which resulted in only about 5%yield increase but 187 yuan per 666.7m2 decrease of net benefit compared to no fertilization;in Weihai and Feicheng, the potato yield in-creased by more than 20%by fertilization, and the net benefit could increase by 400~500 yuan.Overall, ex-cessive fertilizers were applied in the major potato producing areas of Shandong Province, which resulted in low use efficiency of fertilizer and eutrophication of soil and water.So the fertilizer and water management should be strengthened for scientific fertilization during potato production.
