These were used to determine the impacts of three harvesting methods (thinning, coppice-with-standard, and clear felling) combined with three levels of wood utilization (i.e. stemwood only, bole only and bole together with branches) on sustained future productivity within Teak plantation stand. Clear felling combined with any level of wood utilization exerted the greatest impact of loss on the nutrient stores. Thus sustainable production of Teak will be greatly impaired if such harvesting option is solely adopted. On the other hand, thinning above half of the stand density, coupled with stemwood utilization only will increase the nutrient drain four folds, as compared to thinning below half of the stand density and combined with total shoot utilization from the reserves. Furthermore, the rates of depletion were not specific but differed from individual nutrients. Potassium drained from the ecosystem was most rapid, followed by P, N, Mg and Ca. Thus, K and P are likely to severely limit the future productivity of the Teak stand if harvesting options like clear felling or coppice with-standard were to be adopted. The combination of harvesting options and utilization to forecast the potential sustained productivity of Teak plantation stand are discussed.</p> </div> </div> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span lang="" about="/user/3" typeof="schema:Person" property="schema:name" datatype="">sbritwum</span></span> <span class="field field--name-created field--type-created field--label-hidden">Thu, 07/22/2010 - 16:45</span> <div class="field field--name-field-resp field--type-string-long field--label-above"> <div class="field__label">Responsible party</div> <div class="field__item">Forestry Research Institute of Ghana (FORIG)</div> </div> <div class="field field--name-upload field--type-file field--label-hidden field__items"> <div class="field__item"><table data-striping="1"> <thead> <tr> <th>Attachment</th> <th>Size</th> </tr> </thead> <tbody> <tr class="odd"> <td> <span class="file file--mime-application-pdf file--application-pdf"> <a href="https://fornis.net/sites/default/files/documents/sudan_savannah.pdf" type="application/pdf; length=5677273">sudan_savannah.pdf</a></span> </td> <td>5.41 MB</td> </tr> </tbody> </table> </div> </div> <a href="/taxonomy/term/5" hreflang="en">Forests and Climate Change</a> / <a href="/taxonomy/term/9" hreflang="en">Other Information</a> <a href="/taxonomy/term/243" hreflang="en">clear felling</a> / <a href="/taxonomy/term/244" hreflang="en">coppice-with-standard</a> / <a href="/taxonomy/term/245" hreflang="en">nutrient stores</a> / <a href="/taxonomy/term/246" hreflang="en">teak</a> / <a href="/taxonomy/term/247" hreflang="en">wood-harvesting</a> Thu, 22 Jul 2010 16:45:45 +0000 sbritwum 216 at https://fornis.net
