Temporal Variation of N Isotopic Composition of Decomposing Legume Roots and Its Implications to N Cycling Estimates in Tracer Studies in Agroforestry Systems
Sensitivity analysis for the residue application experiment (RA). Change in 15N of the N recipient plant with the change of (a) residue decomposition rate constant, k, (b) C : N of microbial biomass involved in residue decomposition, RB, (c) N source factor for the N recipient plant, Sf, and (d) N uptake rate by the N recipient plant. The actual values in time were varied between −25% and +25% of the values with which the model was optimised. Exact values are given for those parameters which have a fixed value in the model (c, d).
