[Effect of stand condition improvement on surface soil nutrient losses of hilly land Dendrocalamus latiflorus plantations].
A comparative study on the soil nutrient losses of hilly land shoot-used Dendrocalamus lati florus plantations at the Nanjing stated-owned forest farm, Fujian Province showed that the losses of soil N, P and K under three treatments of stand condition improvement varied with season, and 90% or more of these losses appeared from April to September, with the order of overall ploughing > strip ploughing > control. There was no significant difference of N and P losses among the three treatments, while the K loss was markedly higher under overall ploughing than the control.
