Kudzu (Pueraria lobata) is a rapidly spreading liana inthe noodplain of Tama River, Japan. This species is veryrich in secondary metabolites and adds substantial amount of litter into the soil due to its huge biomass tumover in every growing Cycle. This study aims to investigate the seasonal dynamics of major macro- and micronutrients and phenolics in soil associated with the litter productionand growth ofkudzu plants in the downstream of Tama River. Soils were collected &om three kudzu-infested spots alongthe banks of the river and analyzed for total carbon, total nitrogen, total phosphoms, potassium, copper, zinc, sodium and phenolic contents・ The pattems of seasonal changes of those soil elements in all three spots were more or less similar. The levels of the nutrients were related with the growth stages or kudzu plants・ Concentrations of all nutrients except nitrogen went down when the kudzu was at active vegetative stage・ The nutrients were agalnmineralized into the soil after the decomposition ofkudzu litter at winter season・ Soil phenolic contentumder kudzu stand also varied seasonally and the highest quantity was recorded in winter as an outcome ofkudzu litter decomposition・ Soil phenolics was not found to interfere the chemical properties of soil except K, of which concentration in soil was negatively correlated with that of soil phenolics・
