Abstract

Problematic soils such as Beach Ridges Interspersed Swales BRIS can be rehabilitated through planting of fast-growing and non site-demanding tree species. BRIS is an excessively drained soil dominated by sand and has higher surface soil temperature thus only selected species with the ability to tolerate harsh conditions can survive planting with minimal tending input on this site. Acacia species is one the best candidates for planting in such soil conditions and environments. It has the capability to fix the atmospheric nitrogen through root nodules and its roots can also form association with both ecto- and endomycorrhiza AM. A 2.0-ha planting trial of Acacia spp. consisting of Acacia mangium A. auriculiformis and the hybrid of both species was established on Jambu series soil in Setiu Terengganu. The aims of this trial were to determine the most suitable species of Acacia and the best mycorrhizal treatment for planting on BRIS soil. The trial consisted of four treatments i.e. T1-arbuscular mycorrhiza AM inoculum application T2-ectomycorrhizal inoculum ECM application T3-AM ECM application and T4-uninoculated control. All treatments were replicated four times. Survival rate and total height of the plants were monitored at three monthly intervals for the first year and at six-monthly interval thereafter. Foliar analysis was also conducted to determine the nutrient level. At one year after planting results showed that the growth of A. auriculiformis and Acacia hybrid were improved with the application of ectomycorrhiza while A. mangium showed best performance when arbuscular mycorrhiza was applied to either in single or combination with ectomycorrhiza. For species comparison Acacia hybrid outperformed the other two species which showed the highest mean total height of all treatments. However based on height relative growth rate A .mangium seems to perform better than other two species. Based on the chemical analysis of the foliage the level of macronutrient concentrations were almost equal for all treatments except for N. Higher N concentration was observed in A. mangium of all treatments. This could be the influence from nitrogen fixing ability which we expect to differ for each species. However foliar nutrient concentration is also influenced by biomass production and the uptake can only be calculated on biomass measurement. From the overall results this study shows that Acacia hybrid with ectomycorrhizal inoculum and A. mangium with arbuscular mycorrhizal performed best on BRIS soil.
