“…The positive effect of using a mix of native AMF species in the recovery of an area degraded by mining in the Northeast region of Brazil was reported by Souza et al (2012). The authors observed that the mixture of native AMF were more efficient than an exotic AMF isolate (Acaulospora longula) in promoting the growth of Guazuma ulmifolia seedlings at 14 months after planting, especially when the seedlings received less amount of organic fertilizer via manure.…”

The soil microbiota plays an extremely important role in the growth and survival of plants. The presence of some microorganisms can positively and significantly impact the growth of tree species, which can improve the performance of seedlings after planting for commercial purposes and/or for ecosystem restoration. The present study aimed to evaluate the initial growth of seedlings of Hancornia speciosa and Brosimum gaudichaudii associated with microorganisms from the soil of the parent tree and/or inoculated with arbuscular mycorrhizal fungi (AMF). Four substrates were tested: T1 (control) = Autoclaved dystrophic Red-Yellow Latosol (Aut-dRYL) + autoclaved commercial substrate (Aut-CS); T2 = Aut-dRYL + Aut-CS + inoculum of AMF (Mix); T3 = Aut-dRYL + Aut-CS + soil of the parent plant (SPP); and T4 = Aut-dRYL + Aut-CS + SPP + Mix. The AMF inoculum comprised a mix of the species Gigaspora decipiens, Rhizophagus clarus, and Scutellospora heterogama. Seedling growth was determined 270-350 days after transplanting by measuring the following parameters: mycorrhizal colonization rate (MC), abundance of spores (AS), height (H), stem diameter (D), H/D ratio, volume of roots (VR), dry matter of shoot (SDM), roots (RDM), total (TDM), shoot / root dry matter ratio (SDM/RDM), height / shoot dry matter ratio (H/SDM), and Dickson quality index (DQI). The results showed that the addition of SPP improved the growth and DQI of the seedlings, while the AMF mix minimally changed both growth and DQI. The use of symbiotic microorganisms in the nursery in Brazil is scarse due to the difficulty of acquiring these microorganisms and the lack of commercialization of specific isolates for species native to the Cerrado biome. The present study evaluated the use of soil from naturally occurring areas as a source of inoculum. The higher growth and biomass production of inoculated plants support the use of SPP as a form of inoculum and/or inoculation with native AMF to produce seedlings of H. speciosa and B. gaudichaudii.

“…It is important to point out that the absence of a positive response in the growth of seedlings inoculated with AMF does not involve damage to the seedlings in their initial growth (Souza et al 2012). Indeed, in some cases morphological variables related with growth, such as H, D and dry mass, may not be affected.…”

“…Cuenca et al (1998) also found Acaulospora species more frequently in revegetated sites when compared with natural sites. The increased abundance and frequency of some species in the revegetated areas may be due to soil plowing (during disassembly of the dunes) and further spreading of the covering soil in these areas before planting the seedlings, with a more uniform distribution of fungal species in this environment Souza et al 2010Souza et al , 2012Souza et al , 2013.…”

The community of arbuscular mycorrhizal fungi in natural and revegetated coastal areas (Atlantic Forest) in northeastern Brazil

Soil fungi are the key elements in the maintenance of ecosystems, but they are not usually considered when assessing the impact of recovery practices. This study aimed to determine the community composition of arbuscular mycorrhizal fungi (AMF) in natural and revegetated coastal areas of the so-called 'restingas' on the borderline of the tropical Atlantic Forests and to provide information on the recuperation of the soil mycobiota in recovering environments. Soil samples were collected in two consecutive years at four sites (two natural and two revegetated 'restinga' areas), and the fungal communities were identified. Thirty AMF species were identified. Species of Acaulospora and Glomus prevailed in both areas, and the revegetated areas had a higher species richness than the natural areas. The BIO-ENV analysis did not select any soil characteristics that could affect the AMF communities, but the ANOSIM indicated that the AMF communities differed between the 'restinga' areas (Rglobal = 0.621; p \ 0.0001). Because the physicochemical soil factors do not directly influence this relationship, these differences may be due to the biological soil-plant interactions between the areas. Funneliformis halonatus was an indicator of natural 'restinga' areas, but no species was an indicator of the revegetated areas. These areas had a higher species richness, demonstrating that revegetation contributed to the recovery and increased the AMF diversity. The results emphasized the importance of biodiversity inventories in coastal areas subjected to natural and Communicated by

“…Además, la incidencia del biochar y HMA mejoró la tolerancia al estrés hídrico (Hashem et al, 2019). La micorrización de la plántula Guazuma ulmof ilia, podría garantizar la supervivencia de la plántula en el proceso de rehabilitación, estudios observaron una mayor mortalidad de Guazuma ulmifolia en plántulas no inoculadas (tres plantas) y en plántulas inoculadas con la mezcla de AMF nativo (Souza et al, 2012).…”

La minería de carbón es una de las actividades predominantes en el departamento del Cesar, Colombia; esta impulsa el crecimiento económico del país. Después del proceso de extracción del mineral, suele utilizarse capas de suelos acopiados y material estéril para formar suelos artificiales, también llamados suelos mineros; estos, por sus condiciones edáficas poseen cierto grado de toxicidad e infertilidad, que restringe el crecimiento y la supervivencia de los organismos en el medio, dando lugar a la formación de áreas desérticas. La rehabilitación de suelos mineros fomenta el restablecimiento de las condiciones adecuadas, permitiéndole a este ofrecer nuevamente algunos bienes y servicios ambientales. El objetivo fue evaluar el efecto del biochar, los hongos formadores de micorrizas arbusculares (HMA) y NPK en la rehabilitación de suelos mineros, y en el crecimiento de la plántula Guazuma ulmifolia a partir de tres ensayos. Inicialmente se hizo un ensayo de germinación, utilizando semillas de Guazuma ulmifolia, suelos mineros y biochar en concentraciones del 0, 1, 5 y 10%; luego se estableció un ensayo a escala vivero en donde se aplicaron cuatro tratamientos que contenían a la plántula, biochar, HMA y NPK, posteriormente se realizó un ensayo a escala campo utilizando cuatro tratamientos con la plántula, biochar y HMA. Los resultados muestran que el biochar en concentraciones de 1 y 5% incrementó significativamente el porcentaje de germinación, la longitud foliar y biomasa de las plantas; además, se halló un porcentaje de infección del 60% en las raíces de la planta por HMA; así mismo, hubo un aumento importante de pH, fósforo, carbono orgánico, glomalina y actividad enzimática en los suelos, también una reducción significativa en la conductividad eléctrica. El uso de biochar y micorrizas mejoró las propiedades de los suelos y estimuló un mayor crecimiento en la plántula, promoviendo así el proceso de rehabilitación.
