Productivity of paulownia (Paulownia elongata) short-rotation plantation in farm enterprise.
2023
The development of short-rotation multipurpose plantations of fast-growing woody species in farm enterprises is a growing trend worldwide, representing an integrated land management approach with complex efficiency. The initial results of an 8-year observation of paulownia (Paulownia elongata) growth in the plantation in Georgia are discussed. The authors focused on assessing volume and wood biomass per unit area, as well as carbon dioxide (CO2) absorption and carbon (C) sequestration potential. According to the study results, the volume of wood per ha in the plantation (Site 1; 1,5 ha) is 1113 m3, biomass is 499 tons, and carbon stock is 239.5 tons, while the rate of carbon dioxide absorption is 0.88 gg. The average annual increment in volume of the average tree is 0.04-0.06 m3, and biomass is within 0.017-0.027 tons. The study revealed that the development of Paulownia elongata plantations on farm enterprises in Georgia is productive, both for industrial and energy purposes, and as a mitigating factor against climate change.
