Biomass and nutrients of Pinus massoniana plantations in southern China: simulations for different management practices.

Huixia Yang; Silong Wang; Jianwei Zhang; et al. Journal of Food Agriculture & Environment 2011

Other claims from this paper (10)

Association Biomass of each component of Pinus massoniana increased with stand age.
Association The proportion of each biomass component of Pinus massoniana decreased with stand age, except stem-wood.
Intervention effect Lengthening the rotation from 31 to 51 years increased simulated biomass collection by at least 7.1%.
Intervention effect Lengthening the rotation from 31 to 51 years reduced simulated nutrient export for K, Ca and Mg by at most 6.3%.
Intervention effect N and P pools of Pinus massoniana varied with harvesting intensity in the simulation.
Intervention effect Shortening the rotation from 51 to 17 years would increase simulated biomass collection by at least 12.4%.
Intervention effect Shortening the rotation from 51 to 17 years would significantly increase nutrient removal.
Intervention effect Raising harvest intensity would increase biomass collected from Pinus massoniana plantations.
Intervention effect Raising harvest intensity would disproportionately increase nutrient removal from Pinus massoniana plantations.
Recommendation Increasing the rotation length and decreasing harvest intensity are recommended to sustain the site productivity of Masson pine plantations.
