“…This increased prairie plant growth after field planting is consistent with results from other studies of inoculated seedlings (Richter & Stutz ; Middleton et al ; Koziol & Bever ), while restorations using direct inoculation with AM fungi or whole soil without nurse plants have found increased native plant cover and diversity (Smith et al ; Bever et al ). However, our results contrast with a recent restoration where inoculation with one commercially propagated strain of Rhizoglomus irregulare did not affect plant growth (Ohsowski et al ). These observations are consistent with the results of a meta‐analysis by Maltz and Treseder () that found inoculation with native AM fungal strains isolated from undisturbed remnant sites, like the relatively diverse inoculum mixture used here, significantly increased plant growth compared to inoculation using commercially available AM fungal strains that may grow quickly and be amenable to cultivation.…”

“…Despite these potential effects, there are relatively few studies testing the interaction between soil biochar amendments and AM fungi outside of an agricultural setting, and these have found variable outcomes (e.g. Rillig et al ; Warnock et al ; Ohsowski et al ). Given their evolutionary history with biochar, native AM fungi in tallgrass prairies may be especially tolerant of biochar soil amendments or may benefit from them.…”

Little of the historical extent of tallgrass prairie ecosystems remains in North America, and therefore there is strong interest in restoring prairies. However, slow‐growing prairie plants are initially weak competitors with the fast‐growing yet short‐lived weedy plant species that are typically abundant in recently established prairie restorations. One way to aid establishment of slow‐growing plant species is through adding soil amendments to prairie restorations before planting. Arbuscular mycorrhizal (AM) fungi form mutualisms with the roots of most terrestrial plants and are particularly important for the growth of slow‐growing prairie plant species. As prairie ecosystems are adapted to fires that leave biochar (charred organic material) in the soil, adding biochar as well as AM fungal strains from undisturbed remnant prairies into the soil of prairie restorations may improve restoration outcomes. Here, we test this prediction during the first four growing seasons of a prairie restoration. When prairie plant seedlings were inoculated prior to planting into the field with AM fungi derived from remnant prairies, that one‐time inoculation significantly increased growth of five of the nine tested plant species through at least two growing seasons. This long‐term benefit of AM fungal inoculation was unaffected by biochar addition to the soil. Biochar application rates of at least 10 tons/ha significantly decreased Coreopsis tripteris growth but acted synergistically with AM fungal inoculation to significantly improve survival of Schizachyrium scoparium. Overall, inoculation with native AM fungi can help promote prairie plant establishment, but concomitant use of biochar soil amendments had relatively little effect.

“…Several soil ameliorants have been used by many researchers for improving plant growth and development in acidic soil medium (Ohsowski et al 2017;Mrabet et al 2014;Moreira et al 2010).

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.

2Restoration of alpine sand dunes has been increasingly attracting the attention of ecologists due to their 3 difficulty and importance among the mountain-river-forest-farmland-lake-grass system (referred as 4 meta-ecosystem) restoration. Alpine sand dunes are suffered from unstable soil and lack of plants. 5Efficient restoration measures are vital to guide the sand dune restoration. Whether the engineering 6 materials co-applied with seeding could achieve considerable restoration in such areas? Here, sandbag 7 and wicker as environmental friendly materials combined with Elymus nutans seeding were 8 implemented on the Zoige Plateau sand dune, comparing with the 'control' treatment that only seeding. 9We assessed the topsoil conditions by sampled the surface soil and measured the water capacity and 10 nutrients. We also utilized interspecific relationship and population niche to analyse the plant 11 community structure variances among different restoration measures. Results showed that the soil 12 conditions got clearly improved in sandbag area than that in wicker area when compared with that in 13 control area. The community in control area was the least structured, while the species showed the 14 closest related in sandbag area. In addition, average population niche overlap showed a control (0.26) 15 ﹤wicker (0.32)﹤sandbag (0.39) ranking. Thus, we suggested that sandbag or wicker co-applied with 16 indigenous grass seeding is a practical and quick restoration approach in alpine sand dunes, and the 17 sandbag may surpasses the wicker. Moreover, soil amending measures including nutrient improvement, 18and microbial fertilizer addition may further accelerate sand dune restoration. 19 Keywords: interspecific relationship; niche; Elymus nutans; sand barrier; restoration 3 20 Introduction 21The terrestrial ecosystem has experienced increasingly severe land degradation and desertification 22[1]. Desertification threatens the ecological safety and its restoration is one of the vital elements in the 23 mountain-river-forest-farmland-lake-grass system (referred as meta-ecosystem) restoration [2, 3]. The 24 long-termed complex causes (e.g., overgrazing, climate change) accelerate desertification process and 25 the sand dunes are expanding continuously on the Zoige Plateau [4-6]. Sand dunes are generally 26 covered by nutrient devoid sandy soil that lacks favourable properties for plant growth and is prone to 27 wind erosion [7]. The expanded sand dunes destroy fertile land and welfare of local populations. For 28 example, they threaten livestock productivity, society development, ecological civilization, household 29 income or human beings health [8-10]. Hence, sand dunes restoration is crucial in ensuring the 30 conservation and sustainable development of the Zoige Plateau and meeting aspiration for better living 31 standards in local people. 32Decades worth of works have been conducted on sand dunes restoration [11, 12]. Mechanical sand 33 barriers as the classical and simplest measure have been shown to contribute to re...
