Effects of stand condition improvement on surface soil nutrient losses of hilly land Dendrocalamus latiflorus plantations

Abstract

Abstract: A comparative study on the soil nutrient losses of hilly land shoot-used Dendrocalamus latiflorus 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.

Key words: Stand condition improvement, Dendrocalamus latiflorus, Hilly land, Nutrient loss
