Abstract This study aimed to analyze the concentration change of Aluminum in the soil with addition of MycoSilvi and soil ameliorant in silica sand post mining soil media. There are three types of MycoSilvi, single or combination, added with soil ameliorant which tested on Albizia chinensis (Osbeck) Merrill. The experimental design used was a factorial design with two factors, MycoSilvi (M) consisting of four levels (M0 = without MycoSilvi; M1 = MycoSilvi type 1; M2 = MycoSilvi type 2; and M3 = MycoSilvi type 3) and soil Ameliorant (LC) consisting of four levels (L0C0 = without soil ameliorant; L1C0 = lime; L0C1 = compost; L1C1 = lime and compost). Data analysis used analysis of variance (ANOVA). The results showed that the combination of MycoSilvi and soil ameliorant decreased aluminum concentration from 7.70 to 0.10 cmol(+)/kg and increased pH from 3.20 to 5.67 were positively correlated with total biomass. Significant changes were shown in MycoSilvi type 3 with the addition of lime and compost (M3L1C1). Application of MycoSilvi type 3 (M3L0C0) gave equivalent response with application of lime (M0L1C0) to increased dry biomass, so that lime can be replaced with MycoSilvi type 3 (M3L0C0) to promote plant growth, especially biomass of plant.

Abstract. Budi SW, Wibowo C, Sukendro A, Bekti HS. 2020. Growth improvement of Falcataria moluccana inoculated with MycoSilvi grown in post-mining silica sand soil medium amended with soil ameliorants. Biodiversitas 21: 422-427. High aluminum content in soil of post-mining silica sand area inhibits plant growth. MycoSilvi is an inoculum of Arbuscular Mycorrhizal Fungi (FMA) enriched with Mycorrhizal Helper Bacteria (MHBs) which plays an important role for improving plant growth in unfertile soil medium. The aims of this research were to analyze the growth response of Falcataria moluccana (Miq.) Barneby & JW Grimes) seedlings treated with MycoSilvi and soil ameliorants (compost and lime) in post-mining silica sand soil medium. The randomized complete design with factorial scheme was used in this study. The results showed that the interactions of MycoSilvi and Soil ameliorant significantly increased height, diameter, biomass and mycorrhizal colonization of F. moluccana. Combination of MycoSilvi variant 3 and lime increased height, diameter, and biomass of F. moluccana by 965%, 147%, and 1427% respectively, as compared to those of control plants. The mycorrhizal roots colonization in those treatments was 98%. The addition of compost and lime increased pH and decreased Aluminum and Fe of the soil medium. F. moluccana seedlings have high mycorrhizal dependency on post-mining silica sand soil media. These results indicate prospective uses of MycoSilvi and soil ameliorants for improving plant growth in unfertile soil medium, including soil in post-mining area.

Reclamation Process

AbstractWe constructed a mining soil restoration system combining plant, complex substrate and microbe. Sludge was added to reconstructed mine substrates (RMS) to accelerate the reclamation process. The effect of sludge on plant growth, microbial activity, soil aggregate stability, and aggregation-associated soil characteristics was monitored during 10 years of reclamation. Results show that the height and total biomass of ryegrass increases with reclamation time. Sludge amendment increases the aggregate binding agent content and soil aggregate stability. Soil organic carbon (SOC) and light-fraction SOC (LFOC) in the RMS increase by 151% and 247% compared with those of the control, respectively. A similar trend was observed for the glomalin-related soil protein (GRSP). Stable soil aggregate indexes increase until the seventh year. In short, the variables of RMS determined after 3–7 years insignificantly differ from those of the untreated sample in the tenth-year. Furthermore, significant positive correlations between the GRSP and SOC and GRSP and soil structure-related variables were observed in RMS. Biological stimulation of the SOC and GRSP accelerates the recovery of the soil structure and ecosystem function. Consequently, the plant–complex substrate–microbe ecological restoration system can be used as an effective tool in early mining soil reclamation.

   Pakcoy is a type of mustard plant that is quite popular with the community, it is very suitable to be cultivated considering the need for vegetables is quite large. The community's need for fresh and pesticide-free vegetables is a choice now in line with the community's understanding of a healthy diet. Alternatives to fulfillment are chosen by planting with hydroponic media. Hydroponics is a substitute for soil media that can be used to grow vegetable crops. The presence of hydroponics is expected to be able to overcome the narrowing of agricultural land and reduce the use of pesticides considering that pesticides greatly affect human health and the environment.   This study aims to determine the effect of nutritional doses of AB mix agrifarm and age of seedlings and their interactions on the growth and yield of pakcoy plants, this study is carried out in the experimental garden of the Faculty of Agriculture, Tabanan University which began on 9 December 2018 until 12 January 2019.   The study used a Randomized Block Design (RBD) consisting of two factors. The first factor is the nutritional dose of AB mix agrifarm (N) which consists of three dose levels, namely the dose of 850 ppm, 1050 ppm and 1250 ppm. The second factor is the age of seedlings (U) which consists of two seedling age levels, namely the age of seedlings 1 week and 2 weeks. Each treatment is repeated four times.   The results of the study obtained the interaction of dose agrifarm treatment with seed age showed a very significant effect (p 1 0.01) on all parameters except for the parameters of the number of leaves aged 35 days old which showed no significant effect (p 5 0.05). The economical wet weight of plant-1 and BKO of the highest yield of 1-crop yield is produced in the combination treatment of N3U, which amounted to respectively 244.09 g and 78.10g or increased respectively by 57.78% and 293.85% compared to results the lowest produced by the combination treatment of N1U1 is 154.71g and 19.83g

In the present field study, the capability of Canada thistle to develop shoots from intact roots and root fragments at different soil depths was studied. The experiments were performed on four sites with high-density Canada thistle, with three or four replications per treatment. At each site, the soil in the plots was removed layer by layer (to 30 or 40 cm, depending on the site), within a 1 by 1-m quadrat, and spread out on a plastic sheet. All roots and other plant parts were removed, and the soil was either replaced without any root material (two sites), or the roots of the thistles were cut into 10-cm-long fragments and replaced into the source holes (two sites). The measured variables were shoot number and biomass. The number of shoots of Canada thistle decreased with increasing depth (P < 0.001) and increased with time. Additionally, the two factors interacted (P < 0.001) such that shoot development was slower from greater depths. Roots from ≤ 20 cm depth produced higher biomasses than did roots from below 20 cm depth. Replacement of root fragments did not affect the amount of biomass produced. It was concluded that the intact root system contributed considerably more to the total biomass produced by Canada thistle than did the root fragments in the upper soil layers.

This study aims to determine the performance yield component of sweet corn and weed density due to different kinds of fertilizer treatments. This study uses a randomized complete block design (RCBD) in factorial patterns with two factors. The first factor is biofertilizer-Arbuscular mycorrhiza fungi (biofertilizer-AMF) which consists of four levels, namely without biofertilizer-AMF (A0), biofertilizer-AMF 5 g/planting hole (A1), biofertilizer-AMF 10 g/planting hole (A2), biofertilizer-AMF 15 g/planting hole (A3). The second factor is cow manure fermented consisting of three levels, namely without cow manure (B0), cow manure 5 tons ha-1 (B1), cow manure 10 tons ha-1 (B2) with 3 replications so that there are 36 experimental units. The variables observed in this study were: cob length (cm), cob diameter (cm), number of seed rows, cob weight with husk (g), cob weight without husk (g) productivity of sweet corn plants (ton ha-1) and kinds of weeds and their absolute density. The results showed that the highest average corn crop productivity was obtained in the treatment without biofertilizer-AMF and cow manure fermented 10 tons ha-1 (A0B2) as 8.52 tons ha-1. If the combination of treatments contained biofertilizer-AMF and cow manure fermented, the highest average productivity of sweet corn was obtained in the treatment of biofertilizer-AMF 5 g/planting hole and cow manure fermented 10 tons ha-1 (A1B2) as 7.19 tons ha-1. The highest weed density from broadleaf is H.capitata (34.167%), from grasses is I.cylindrica (32.432%) and from sedges is Cyperus sp (30.21%).
