A comparison of total organic carbon, nitrogen, phosphorus, and soil microbial biomass between the rhizosphere of two plants, Paris polyphylla and Panax japonicus, reveals their differing effects on soil traits and nutrient cycles.
P. japonicus had the highest total organic carbon, total nitrogen, and microbial nitrogen, while P. polyphylla had the highest total phosphorus and microbial biomass phosphorus.
Despite changes in soil nutrient levels from monoculture planting, neither species created nutrient deficiencies, indicating different nitrogen and phosphorus demands, and raising questions about the ecological implications of their distinct soil influences.
