A model (WANULCAS), still under construction, which uses the STELLA II model representing a 4-layer soil profile, a water and N balance and uptake by a crop and a tree is described. The model allows for the evaluation of different pruning regimes, hedgerow spacings and rates of application of fertilizer. The description of water and nutrients uptake is based on root length densities, plant demand and the effective supply by diffusion at a given soil water content. The model is suitable for simultaneous and sequential agroforestry systems, incorporates management options and will be tested using the Lampung dataset.</style></abstract><auth-address><style face="normal" font="default" size="100%">ICRAF-SE Asia, PO Box 161, Bogor 16001, Indonesia</style></auth-address></record></records></xml>
