This work presents a Multi-Agent System model that describes "vegetation" agents in the presence of a contaminant, with an initial homogeneous random distribution within a habitat represented by a circular habitat. Vegetation agents exhibit linear growth and senescence rates governed by local and global rules, resulting in emergent sigmoid net growth. Each vegetation agent produces a seed during a specific phase of its life cycle, based on density-dependent rules for each agent. These agents are characterized by their aerial and root biomass, regulated by the root/aerial part allometric relationship. Initially distributed randomly in patches with a certain surface density of total biomass, agents can grow, shrink, or even disappear from the habitat. The model incorporates intraspecific competition for resources through the root system. The model also simulates the uptake of the contaminant by the vegetation agent through the roots, its distribution and accumulation. Finally, the relationship between the seed production phase and the optimization of a contaminant extraction-based phytoremediation process is analyzed.
