Abstract: Maize plants and soil samples were collected from Jilin Province to study the nutrient dynamics in soil maize plant rhizosphere and their relationship with plant uptake.The results showed that NH₄⁺-N and NO₃^--N were accumulated in rhizospheric soil, and mainly controlled by the application of chemical fertilizers.Soil available P was depleted in high fertility fields,especially in high seedling density,while accumulated in low fertility fields.Soil available K was accumulated in rhizospheric soil,and its accumulation rate was higher in high fertility than in low fertility fields.The nutrient absorption amount was N≈K>P for maize plant shoots and roots,but was N>K>P for seeds.The contribution rate of chemical fertilizers to maize yield was only 1/5～1/3 in Jilin Province,and the rest was contributed by the application of organic manure,such as chicken feces or cow feces,and by the mineralization of soil organic matter.
