In order to find out the situation of fluvo-aquic soil nutrients of spring corn in Yuyang District of Yu]in City,the farmers'ferti]ization levels were investigated ,the soil samples were determined,and compared to results of the second national land survey to analyze the change regular. The results showed that the contents of soil nutrients presented an increasing trend,but available potassium decreased,and further fertilization principles were proposed.
