| Abstract: | This work was carried out in the fern (D. Liners Underw) ecosystem which is under a chinese fir community, for understanding the nutrient dynamics, distribution and cycling of this ecosystem. The result obtained shows the concentration and storage characteristics of the nutrient elements N,P,K, Ca, Mg, Al, Mn. The turnover period,utilize coefficient, absorption coefficient of seven elements also have been shown in the paper. |
