We analysed the temporal dynamic variation of nutrients in various organs and the soil in a Camellia oleifera low-yield forest in Changning. The results showed that the total N, Ca, and K had the highest demand during the different growth stages of C. oleifera, while Mg and P had the least. The trace elements that were in demand were Mn, Fe, Cu, and Cd. Available N and Mg were the soil nutrients supplied during the spring growth stage, and available K, total N, total P, Fe, and organic matter were the main soil elements supplied during the summer growth stage. The main soil nutrient element supplied during fructescence was total K, while the main soil elements supplied during florescence were available P and Ca. The nutrient demand of C. oleifera at different times differed:spring growth stage (28.36%) > summer growth stage (26.17%) > fructescence (22.75%) > florescence (22.73%). The soil nutrient supply was as follows:spring growth stage (2999.83 ±87.04 mg/kg) > summer growth stage (2703.93 ±292.26 mg/kg) > fructescence (2554.60 ±508.84 mg/kg) > florescence (2385.88 ±199.62 mg/kg). The nutrient demand did not correspond with the soil nutrient supply at the different growth stages. The results provide a scientific basis for allocating the time for fertilisation and variations in the nutrient demand and supply for C. oleifera low-yield forest and indicated that fertilisation should be increased in the spring growth stage.
