This paper presented the effects of slash management on tree growth of Acacia auriculiformis plantation and chemical property of soil during first four years. Retention of slash increased the volume growth by 7-10% depending on the amount of retained slash. At the same time, slash residues impacted and improved soil properties through increasing of Nitrogen and Organic carbon while it is considered that available phosphorus as well as exchangeable cations potassium (K), calcium (C) and magnesium (Mg) in soil declined after 3 years by using nutriment of planted trees.
Overall productivity of A. auriculiformis plantation in second rotation crop(2R) compared to the first(1R) showed those high productivity potential by slash retention. The slash retention after harvesting will be recommended for planting practices to ensure sustainable productivity of Acacia auriculiformis plantations in Vietnam.
