A pot study on the effect of arbuscular mycorrhiza (AM) and phosphate rock (PR) on root development and nodulation of Acacia mangium seedlings on degraded (tin tailing) soils was conducted in the glasshouse of Universiti Putra Malaysia (UPM), Malaysia. Two arbuscular mycorrhiza (AM) inoculation treatments, viz., (i) with AM and (ii) without AM in combination with three P sources like Gafsa phosphate rock (GPR), China phosphate rock (CPR) and triple superphosphate (TSP) including a control (without P) were studied in split plot design. Six sets of this treatment combination were established for destructive sampling at 60, 75, 90, 105, 120 and 135 days after planting (DAP). Root biomass yields and root volume of inoculated seedlings given TSP and GPR were identical and superior to that with other treatments throughout the study. The P sources were in the order of TSP>GPR>CPR for enhancing root development irrespective of AM inoculation. The uninoculated seedlings required 15 to 20 more days to produce an equivalent root biomass to that of inoculated seedlings. Number and weight of nodules of AM inoculated seedlings given TSP and GPR were also higher than those with other treatments. As a cheaper source GPR in combination with AM might be used for growing A. mangium seedlings on degraded tin tailings.

Plot Design

The experiment was conducted in the degraded ex-tin mining farm of Universiti Putra Malaysia during November 1998 to May 1999. The experiment was laid out in split plot design with three replications. Three phosphorus (P) rates, viz., 0, 50 and 100 g Gaphsa phosphate rock (GPR) per plant in combination with and without arbuscular mycorrhiza (AM) inoculation were studied on newly planted tree species Acacia mangium. Mycorrhiza inoculation was assigned to the main plot and P dose to the subplot. Three-month-old AM preinoculated seedlings were planted in the field at 2 m x 2 m spacing. The experiment was continued until 160 days after planting (DAP). Mycorrhiza inoculation and rate of P application significantly influenced growth and development of the A. mangium plants. The highest growth of un-inoculated A. mangium plants was observed with 100 g GPR per plant; whereas for AM inoculated plants the highest growth was observed with 50 g GPR per plant. This indicates that P requirement of newly planted A. mangium plants on degraded ex-tin mining land could be reduced to 50 g GPR per plant, i.e., by 50% with AM inoculation.

Increasing material, processing, and distribution costs have raised superphosphate prices to a point where many farms cannot support the costs of meeting maintenance phosphate requires men& Alternatives to superphosphate, particularly those that have lower processing costs and contain more P, may offer a solution to the problem provided they are agronomically as effective. Phosphate rock may indeed be such an alternative. Preliminary results from a series of five trials in Northland show that on soils of moderate P fertility, with low phosphate retention (PR) and high pH (5.9.6.0), initial pasture growth responses to rock phosphates are smaller than those from single or triple superphosphate. On one soil of higher PR and lower pH, the differences in yield between the rock-phosphates and the super. phosphates were smaller. Of the rock phosphates tested, Sechura and North Carolina (unground and ungranulated) tended to be more effective than ground and granulated Chatham Rise phosphorite. The effect on production of applying fertilisers once every three years, as opposed to annual applications is being investigated using triple superphosphate and Sechura phosphate rock. After two years, production levels appear largely unaffected by differences in application frequency. A comparison of locally-produced superphosphate with a reference standard showed that both performed similarly, indicating that the local product was of satisfactory quality.

Timber Acacia mangium (Acacia mangium, Willd) for Furniture. The study aims to determine the mechanical and physical properties and the decorative value (color and fiber) wood of acacia mangium with using finishing materials. This type of finishing material used is ultran lasur natural dof ,ultran lasur classic teak, aqua politur clear dof, aqua politur akasia dan aqua politur cherry. After finishing the wood is stored for 3 months. Test parameters were observed, namely, physical and mechanical properties of wood, adhesion of finishing materials, color and appearance of the fiber, and timber dimensions expansion. The results showed that the mechanical physical properties of acacia wood qualified SNI. 01-0608-89 about the physical and mechanical properties of wood for furniture, air dry the moisture content from 13.78 to 14.89%, flexural strength from 509.25 to 680.50 kg/cm2, and compressive strength parallel to fiber 342.1 - 412.9 kg/cm2. Finishing the treatment process using five types of finishing materials can increase the decorative value (color and fiber) wood. Before finishing the process of acacia mangium wood has the appearance of colors and fibers and less attractive (scale scores 2-3), after finishing acacia wood fibers have the appearance of colors and interesting and very interesting (scale 4-5).Keywords: mangium wood, mechanical properties, decorative value, finishing, furniture.

The research was conducted at Soroan, Ayamaru District, South Sorong, Papua. �The objective of the study was to observe the diversity of Arbuscular Mycorrhiza Fungi (AMF) that symbiosis with cultivated plants at the Ayamaru rock phosphates deposit. Based on the observation, there were four AMF associated with nine cultivated plants at the Ayamaru rock phosphates deposit, namely genus Glomus, Acaulospora, Sclerocystis and Gigaspora. Genus Glomus had the greatest diversity (13 types) followed by Acaulospora which comprised of seven types.� On the other hand, the diversity of genus Sclerocystis and Gigaspora only consisted of two types and one type, respectively.
