Description

We assessed the profitability of low-density planting on the reduction of planting cost and felling income. We used multiple stage projection alternative technique (MSPATH) algorithm to search the benefits associated with thinning regime. In addition, we assessed the influence of subsidies on thinning regime. The net present value (NPV) increased with a decrease in initial tree density irrespective of the extent of the subsidy. The primary conclusion of this research is that low-density planting was effective in terms of both income and cost under assumption of this study.
