“…Only the genus Glomus was found in this study, which could be due to the higher adaptability of the Glomus [22]. This is in agreement with the study by Tuheteru et al [21] who reported that Glomus was the dominant AM fungi in the soil of the gold mining area in Southeast Sulawesi, and Alimi et al [22] in the grassland in South Africa.…”

Arbuscular mycorrhiza (AM) is a mutualistic symbiosis between soil fungi and plants, including dogfruit (Archidendron pauciflorum). Archidendron pauciflorum is a local plant from Southeast Asia, including Indonesia that is used for food and animal forest feed. Planting A. pauciflorum seedlings on revegetation land with a sharp slope is difficult and dangerous to workers. Therefore, seed-ball planting technique is required for revegetation of post-mining sharp slope areas. This research aimed to study the ability of the native AM fungi to colonize A. pauciflorum seedlings grown as a seed-ball in the field for revegetation purposes. The seed-ball was made using three types of fungal inoculum sources, namely control without AM fungi, natural forest, and stockpile inoculum. All colonization structures, such as entry points, coils, arbuscules, and vesicles, were observed. All seedlings were colonized by AM fungi, with root colonization ranging from 2% to 16%. Stockpile inoculum had a higher AM colonization than the natural forest inoculum. Both sources of native AM fungi tended to improve the growth of the seedling. There were two types of AM spores found in all treatments, Glomus sp. 1 and Glomus sp. 2. Glomus sp. 2 is the dominant species of AM fungi in all treatments.

“…The positive interactions involve the nutrient acquisition, biological control of root pathogens, improvement of plant tolerance to abiotic stresses, and soil fertility. AMF communities influence the physicochemical environment of the rhizosphere and control various soil microbial interactions (Alimi et al, 2021 ). Mycorrhization directly affects the quantity and quality of root exudates.…”

Many of the world's soils are experiencing degradation at an alarming rate. Climate change and some agricultural management practices, such as tillage and excessive use of chemicals, have all contributed to the degradation of soil fertility. Arbuscular Mycorrhizal Fungi (AMFs) contribute to the improvement of soil fertility. Here, a short review focusing on the role of AMF in improving soil fertility is presented. The aim of this review was to explore the role of AMF in improving the chemical, physical, and biological properties of the soil. We highlight some beneficial effects of AMF on soil carbon sequestration, nutrient contents, microbial activities, and soil structure. AMF has a positive impact on the soil by producing organic acids and glomalin, which protect from soil erosion, chelate heavy metals, improve carbon sequestration, and stabilize soil macro-aggregation. AMF also recruits bacteria that produce alkaline phosphatase, a mineralization soil enzyme associated with organic phosphorus availability. Moreover, AMFs influence the composition, diversity, and activity of microbial communities in the soil through mechanisms of antagonism or cooperation. All of these AMF activities contribute to improve soil fertility. Knowledge gaps are identified and discussed in the context of future research in this review. This will help us better understand AMF, stimulate further research, and help in sustaining the soil fertility.

“…In the soil from the rhizosphere of upland rice, Acaulospora, Gigaspora, and Glomus spores were found for all treatments, as shown in Figure 2. The three AMF genera were often dominant in the soil of the rhizosphere of upland rice and other plants (Olubode et al 2020;Alimi et al 2021;Baki et al 2021). Sporulation and germination of AMF spores were colonized and then infected upland rice roots, as indicated by the presence of external hyphae, internal hyphae, vesicles, arbuscles, and spores (Campo et al 2020).…”

Abstract. Rakian TC, Kilowasid LMH, Afa LO, Riskyana A, Nurazizah, Wijayanti Y, Bahrun A, Subair I, Rahni NM, Alam S, Sarawa, Karimuna L. 2023. Soil biological quality in rhizosphere, growth, and yield of upland rice grown on acid soil after amended biochar enriched sap of Kappaphycus alvarezii. Biodiversitas 24: 6780-6792. Biological soil quality is essential in evaluating soil management practices using biochar enriched for upland rice growth on acid soil. Therefore, the study aimed to (i) analyze the effect of biochar-enriched sap of Kappaphycus alvarezii (K-sap) on the abundance of Arbuscular Mycorrhizae Fungi (AMF), bacteria, and protozoa in rhizosphere soil, growth, and yield of upland rice, and (ii) the relationship between the abundance of soil biota and the growth and yield components, as well as straw N, P, and K content on acid soil. Four upland rice were grown on acid soil incubated with biochar-enriched sap for two weeks in pots. Nine treatments of the biochar-enriched sap were tested, namely control, 5% biochar-0% K-sap, 5% biochar-5% K-sap, 5% biochar -10% K-sap, 5% biochar-15% K-sap, 7.5% biochar-0% K-sap, 7.5% biochar-5% K-sap, 7.5% biochar-10% K-sap, and 7.5% biochar-15% K-sap. Each treatment was three replicates in a randomized block design. The results demonstrated that the AMF spores quantity decreased while flagellates increased in the soil rhizosphere. The P and K content increased, the N:P decreased, and P:K ratio varied in the straw of the upland rice. Plant height and total spikelets increased, while root dry weight and roots to shoots ratio (R:S) decreased with biochar enriched. The abundance of AMF spores and flagellates correlated positively and negatively with R:S. Furthermore, R:S was negatively correlated with plant height and total spikelets. Plant height and total spikelets showed a positive correlation, while root dry weight and R:S was negatively correlated with K content in shoot tissue. The P and K contents with N:P ratio and N:P with P:K were negatively correlated. In conclusion, biochar-enriched K-sap effectively regulated the activity and composition of soil biota in the rhizosphere, influencing upland rice's growth, yield, and nutrient balance uptake on acid soils.
