Abstract

We investigated in field experiments seasonal dynamics of acid and alkaline phosphatase activity. Alkaline and acid phosphatase activity showed a seasonal pattern. Alkaline phosphatase activity was significantly higher in springandacid phosphatase activity significantly higherin autumn.Soil phosphorus activity in spring is considerably higher than soil phosphorus activity in the autumn.Fraxinus rotundifolia,The results showed that average plant phosphorusin spring higher than the autumn but difference between average plant phosphorus on the treatments (spring and autumn) was not significant. Average plant phosphorusin spring higher than the autumn but difference between average plant phosphorus on the treatments (spring and autumn) was not significant. The results of correlation analysis indicated that there wassignificant correlation among alkaline phosphatase with available phosphorus.
