Allometry and partitioning of above- and below-ground biomass in farmed eucalyptus species dominant in Western Kenyan agricultural landscapes

摘要: Abstract Farmers in developing countries are one of the world's largest and most efficient producers sequestered carbon. However, measuring, monitoring verifying how much carbon trees smallholder farms removing from atmosphere has remained a great challenge nations. Devising reliable way for measuring associated with agricultural landscapes is essential helping farmers benefit emerging markets. This study aimed to develop biomass equations specific dominant eucalyptus species found Western Kenya. Allometric relationships were developed by regressing diameter at breast height (DBH) alone or DBH combination height, wood density crown area against 48 destructively sampled 100 km2 site. was significant predictor variable estimated aboveground (AGB) over 95% accuracy. The stems, branches leaves formed up 74, 22 4% AGB, respectively, while belowground (BGB) harvested accounted 21% total tree biomass, yielding an overall root-to-shoot ratio (RS) 0.27, which varied across size. Total held live Eucalyptus be 24.4 ± 0.01 Mg ha−1, equivalent 11.7 ± 0.01 Mg per hectare. presented provide useful tools estimating stocks bio-energy accounting. These can applied systems similar agro-ecological settings where growth parameters would fall within ranges comparable population.
