Managing soil fertility in eucalypt plantations in China
More than 1.5 M ha of eucalypt plantations have been established in south China, increasing by about 100,000 ha y. Productivity is uneven and low, only about 25-50% of the world average for eucalypt plantations. Most land available for eucalypts are degraded oxisols and utilsols which also are acidic, highly leached and deeply weathered. Phosphorus deficiency is very severe and its availability...
متن کاملA Forest Simulation Model for Predicting Eucalypt Dynamics and Habitat Quality for Arboreal Marsupials
A forest simulation model (called EDEN) of eucalypt dynamics in southeastern Australia is presented to predict habitat quality for arboreal marsupials. The model is presented as a tool for testing alternative hypotheses of forest management in the study area, EDEN uses a forest gap simulation (IABOWA/FORET type) model as a pattern generator of habitat in different landscape positions and under ...
متن کاملA Robust Productivity Model for Grapple Yarding in Fast-Growing Tree Plantations
New techniques have recently appeared that can extend the advantages of grapple yarding to fast-growing plantations. The most promising technique consists of an excavator-base un-guyed yarder equipped with new radio-controlled grapple carriages, fed by another excavator stationed on the cut-over. This system is very productive, avoids in-stand traffic, and removes operators from positions of hi...
متن کاملShape of Skidder Productivity Function for Ground Based Skidding System in Caspian Forests
Cut-to-length (CTL) timber harvesting technology currently accounts for approximately 90% of Caspian forests. The technology involves felling, branching, cross-cutting, and then the skidder carries the logs to a landing, where the timber is temporarily stored, sorted and assembled for transportation to the mill. Cut-to-length systems typically require less labor, less access road construction, ...
