Modelling root architecture and phosphorus uptake in agroforestry

A modified version of the WaNuLCAS model [Water, Nutrient and Light Capture in Agroforestry Systems, which models water, nitrogen and light interactions in agroforestry systems] is outlined. The modified model includes phosphorus as a second nutrient, with a range of phosphorus (P) acquisition mechanisms for crops and trees, and interactions via recycling and rhizosphere modification
