摘要：

Annual changes in biomass C, N and P were followed in two soils from the Rothamsted Classical Experiments that have been under the same management for > 100 yr, one under continuous wheat and the other under grass. Sampling was at approximately monthly intervals, over a period of ca 1 yr. Annual changes were small in both soils and largely masked by experimental and sampling error. Over the year, the arable soil (0-23 cm) contained a mean of 689 ± 11.6 kg biomass C ha-1, 154 ± 2.9 kg biomass N ha-1 and 47 ± 3.3 kg biomass P ha-1, The corresponding means for the grassland soil were 1121 ± 24.6 kg biomass C ha-1, 255 ± 10.4 kg biomass N ha-1 and 129 ± 4.8 kg biomass P ha-1. © 1990.
