Abstract This paper took soils from lotus fields in Guangchang County of Jiangxi Province as research object；measured the contents of medium and trace element contents of lotus field soils from 6 main production villages and towns；evaluated their nutrient abundance and deficiency；and analyzed their spatial variation characteristics．The results showed that the contents of exchangeable calcium （ex. Ca）and exchangeable magnesium（ex. Mg）were 834 ± 493 mg · kg-1 and 88.4 ± 22.4 mg · kg-1， respectively；available sulfur（av. S）was 28.9 ± 12.4 mg · kg-1，available boron（av. B）was 0.19 ±0.09 mg · kg-1，respectively；available zinc（av. Zn）and available copper（av. Cu）were 6.42 ± 3.09 mg · kg-1 and 5.02 ± 2.41 mg · kg-1，respectively；available iron（av. Fe）and available manganese（av. Mn）were 529 ± 120 mg · kg-1 and 71.5 ± 31.1 mg · kg-1，respectively；available molybdenum（av. Mo）content was 0.12 ± 0.19 mg · kg-1．The contents of ex. Ca，ex. Mg and av. S in lotus field soils were all lower．Among them the lack of ex. Mg was the most prominent．In trace element，the contents of av. B and av. Mo were very lower，whereas the contents of av. Zn，av. Cu，av. Fe and av. Mn were generally higher．Attention should be paid to the excessive contents of av. Fe and av. Mn．According to the spatial variation characteristics of medium and trace elements，in Yiqian Town seed lotus producing area attention should be paid to the lack of ex. Ca and ex. Mg and excessive av. Fe and av. Mn in soils． In Toupi Town and Xujiang Town seed lotus producing area，attention should be paid to the lack of av. S and av. B in soils.
