Determination of nutrient resources can be return to the land of A. auriculiformis plantation in Phu Binh - Binh Duong
Keywords:
Litter fall,, slash retention,, biomass, soil nutrientAbstract
The study was conducted to determine the dry biomass and nutrients from three sources: (i) slash retention after havesting of the previous rotation; (ii) shrubs, vegetation, litter under the forest canopy; (iii) litter fall of Acacia auriculiformis plantation in the next rotation in Phu Binh - Binh Duong. Results showed that: total accumulative dried biomass of these three sources in Acacia auriculiformis plantations at age 5 is about 55.05 tons/ha, nutrient equivalent potential for soils is: 659.01kg N/ha, 61.35kg P/ha, 327.36kg K/ha, 58.43kg Ca/ha and 24.11kg Mg/ha. This nutrition will help improve soil fertility and sustainable productivity of Acacia auriculiformis plantation in the next rotation.
