Abstract:

Extractable nutrient levels in a floodplain forest soil varied significantly over the course of a year. Temporal variation in nutrient pools expressed as the ratio range/mean was in the following order: NH4-N > NO3-N ยป extractable P > exchangeable K > exchangeable Mg > exchangeable Ca. Lowest concentrations occurred during the summer months for all nutrients except NO3-N. The magnitude of this variation exceeded the size of several other nutrient fluxes within the ecosystem, which indicated that the soil system was a dynamic component of the floodplain forest ecosystem. Considerable evidence from diverse soil and vegetation types suggests that temporal variation in soil nutrient levels is a feature common to most temperate forest ecosystems. Forest Sci. 32:318-324.
