Abstract
Acacia plantation in different quality sites and fertilization in Northeast Vietnam
Highlights
Fertilization has been widely applied in many species around the world to increase forest plantation productivity (Shi et al, 2019; Hung et al, 2009), and it is a viable silvicultural option for sustainable plantation management (Fox et al, 2007)
The objective of this study is to examine the effect of fertilization in different quality sites on Acacia mangium plantation in northeast Vietnam
Site and fertilization significantly affected the growth of 1- and 2-year-old A. mangium plantations (Table 2)
Summary
Fertilization has been widely applied in many species around the world to increase forest plantation productivity (Shi et al, 2019; Hung et al, 2009), and it is a viable silvicultural option for sustainable plantation management (Fox et al, 2007). Site quality has the greatest and often longest-lasting effect on the productivity of plantations. Fertilization on high fertile sites often has little effect, while that on low fertile sites can have remarkably positive effects. The macronutrients (Sulaiman et al, 1990) including Nitrogen (N), Phosphorus (P), and Potassium (K) are the key limiting nutrients in many sites (Goncalves et al, 2007). Fertilizers could be applied at and/or after planting annually to support tree’s growths (Vu et al, 2019; Tran et al, 2018; Tran et al, 2017; Guo et al, 2016; Lamani et al, 2004).
