原始语种摘要: To increase productivity of forest plantation, fertilization has been widely applied, especially in poor soil condition, of which Nitrogen (N), Phosphorous (P), Potassium (K) and compost are usually used. The amount is decided basing mainly on species and soil condition. The objective of this study is to examine the effects of fertilization on growth of acacia plantations. Four fertilization treatments (100 g NPK+200 g compost, 150 g NPK+150 g compost, 200 g NPK+100 g compost, and control) were applied at planting for Acacia hybrid and Acacia auriculiformis plantations with planting density of 1,330 trees ha-1 (spacing 2.5 × 3 m) in Northeast Vietnam at 21o38’N and 107o32’E. Data included survival rate, diameter at breast height (DBH), stem height, and crown diameter (Dc) were collected,...
