Abstract

The success of revegetation in the context of forest land rehabilitation and post-mining land reclamation is often often caused by constraints due to marginal land conditions, such as high acidity/alkalineity, low organic matter content, and low availability of macro nutrients. Mycorrhiza Biofertilizer (MB) is one alternative technology that has been reported to be able to increase the success of the rehabilitation. Forest farmers, as one of the actors in forest rehabilitation activities, do not yet have sufficient knowledge and skills in developing biofertilizer such as MB. The objectives of theis community services were to introduce and improve forest farmer about the MB, as well as to establish the demonstration plot for MB development. The result showed that field training and counseling on mycorrhiza and its benefits, as well as the manufacture of mycorrhizal biofertilizers have been carried out in Cisangku, Malasari village, Bogor Regency involving Forest Farmers Model Conservation Village (KTH MKK). The counseling and training were attended by 25 forest farmer participants. Based on the postest carried out after the implementation of counseling and training, there was an increase in farmers' knowledge about mycorrhizal and its benefits as well as procedures for developing mycorrhizal fertilizers. The participants wer also satisfied and increased their skill in preparing mycorrhizal culture materials and caring for their selves. The participating farmers were even willing to develop MB independently if they have sufficient skills and know the benefits. The increasing knowledge and skills of forest farmers had an impact on improving the quality of forest farmers in supporting forest rehabilitation and becomes an alternative of additional income.

Abstract

One of the problems with acidic soil is its high aluminum (Al) content, which can cause toxicity to plants. this study was conducted to evaluate the preliminary growth and tolerance of L. leucocephala seedlings to Al exposure. This study used a completely randomized design (CRD) with one factor, namely Al concentration, consisting of 5 levels (0, 2, 4, 6, and 8 mM). The evaluation of seedling growth and tolerance assessed included: height, root length, dry weight of roots and shoots, tolerance index, SPAD (Soil Plant Analysis Development) chlorophyll, and photosynthesis rate. The results showed that Al exposure reduced all growth parameters (height, root length, dry weight of roots and shoots) of L. leucocephala seedlings. The tolerance index of L. leucocephala seedlings also decreased significantly (up to 43.68%) with increasing Al concentration. Meanwhile, chlorophyll and photosynthesis rate parameters increased with Al exposure of 2-4 mM, but decreased with higher Al exposure (6-8 mM). The threshold value or sensitivity of L. leucocephala seedlings to Al exposure was less than two mM. The L. leucocephala species can also serve as an alternative for land rehabilitation with high Al content as post-coal mining land.

Abstract

Aluminum (Al) is one of the problems and is a factor inhibiting plant growth on soils with acidic pH. This study aims to examine the growth response of Eucalyptus pellita and Eucalypus Deglupta seedlings to Al exposure. This study used a completely randomized design (CRD) with one factor, where the Al concentration consisted of 5 levels, namely: 0 mM (control), 2 mM, 4 mM, 6 mM, and 8 mM with 3 repetitions each and each repetition consisted of 3 units of the plant. The results showed that Al treatment had a significant effect on the growth parameters of both plant types, except for the root dry weight parameter for E. deglupta. Increasing the Al concentration can reduce almost all growth parameters. The 4 mM Al concentration was able to increase the height growth, plant dry weight (roots and shoots), and tolerance index for the E. pellita species, while the Al 2 mM concentration was able to increase the root growth of E. deglupta plants. Almost all growth parameters for E. pellita species were higher than that of E. deglupta, except for the SPAD chlorophyll index. The concentrations of 6 mM and 8 mM were toxic to E. pellita and E. deglupta.
