The knowledge of the survival of inoculated fungal and bacterial strains in field and the effects of their release on the indigenous microbial communities has been of great interest since the practical use of selected natural or genetically modified microorganisms has been developed. Soil inoculation or seed bacterization may lead to changes in the structure of the indigenous microbial communities, which is important with regard to the safety of introduction of microbes into the environment. Many reports indicate that application of microbial inoculants can influence, at least temporarily, the resident microbial communities. However, the major concern remains regarding how the impact on taxonomic groups can be related to effects on functional capabilities of the soil microbial communities. These changes could be the result of direct effects resulting from trophic competitions and antagonistic/synergic interactions with the resident microbial populations, or indirect effects mediated by enhanced root growth and exudation. Combination of inoculants will not necessarily produce an additive or synergic effect, but rather a competitive process. The extent of the inoculation impact on the subsequent crops in relation to the buffering capacity of the plant-soil-biota is still not well documented and should be the focus of future research.

AbstractPlant-soil feedbacks are shaped by microbial legacies that plants leave in the soil. We tested the persistence of these legacies after subsequent colonization by the same or other plant species using 6 typical grassland plant species. Soil fungal legacies were detectable for months, but the current plant effect on fungi amplified in time. By contrast, in bacterial communities, legacies faded away rapidly and bacteria communities were influenced strongly by the current plant. However, both fungal and bacterial legacies were conserved inside the roots of the current plant species and their composition significantly correlated with plant growth. Hence, microbial soil legacies present at the time of plant establishment play a vital role in shaping plant growth even when these legacies have faded away in the soil due the growth of the current plant species. We conclude that soil microbiome legacies are reversible and versatile, but that they can create plant-soil feedbacks via altering the endophytic community acquired during early ontogeny.

Land resources are finite, comprised with biophysical complexities (biodiversity, soil, and water resources), vital in sustenance of life. However, multiple anthropogenic disturbances transmogrified the global landscapes with spread of invasive alien plants (IAPs), and perturbed the land-biophysical components, thereby triggering the ecosystem degradation. Nevertheless, the interrelationship of IAPs with land degradation and sustainable restoration is not well established. Furthermore, the restoration challenges of IAPs driven land degradation is also exacerbated under the event of climate change. In this review, the adverse impacts of IAPs on biophysical components of land resources are discussed to explicitly assess the drivers of ecosystem degradation. Restoration efforts of degraded lands should be therefore targeted to revitalize the associated biophysical complexities. Further, the explicit study on the effects of IAPs on plant-soil and plant-soil microbe interactions need to be at the heart of sustainable land or ecosystem restoration strategies. Several studies refused the blanket condemnation of IAPs in ecosystem restoration, ascribed to co-benefits (bioenergy, phytoremediation, biopolymers, and ethnomedicines), inextricably linked with the coverage of financial incentives. Nevertheless, the use of IAPs in ecological restoration needs pragmatic evaluation in terms of long-term ecosystem effects. To this end, the incorporation of ‘hybrid technology’, integrating scientific information with traditional ecological knowledge (TEK), can be the founding principle of sustainable ecosystem restoration and rural livelihood. Importantly, holistic approach in restoration of degraded lands in concert with ‘circular economy’ can remarkably influence in achieving the target of UN Sustainable Development Goals (UN-SDGs) and UN Decade on Ecosystem Restoration (UN-DER) (2021-30).

Loss of beneficial microbes and lack of native inoculum have hindered reforestation efforts in the severely-degraded lands worldwide. This is a particularly pressing problem for Ethiopia owing to centuries-old unsustainable agricultural practices. This study aimed to evaluate the inoculum potential of soils from church forest in the northwest highlands of Ethiopia and its effect on seedling growth of two selected native tree species (Olea europaea and Albizia gummifera) under a glasshouse environment. Seedlings germinated in a seed chamber were transplanted into pots containing sterilized and/or non-sterilized soils collected from under the canopy of three dominant church forest trees: Albizia gummifera (AG), Croton macrostachyus (CM), and Juniperus procera (JP) as well as from adjacent degraded land (DL). A total of 128 pots (2 plant species × 4 soil origins × 2 soil treatments × 8 replicates) were arranged in a factorial design. Overall, seedlings grown in AG, CM, and JP soils showed a higher plant performance and survival rate, as a result of higher soil microbial abundance and diversity, than those grown in DL soils. The results showed significantly higher plant height, root collar diameter, shoot, and total mass for seedlings grown in non-sterilized forest soils than those grown in sterilized soils. Furthermore, the bacterial relative abundance of Acidobacteria, Actinobacteria, and Nitrospirae was significantly higher in the non-sterilized forest soils AG, CM, and JP (r2 = 0.6–0.8, p < 0.001). Soil pH had a strong effect on abundance of the bacterial community in the church forest soils. More specifically, this study further demonstrated that the effect of soil microbiome was noticeable on the performance of Olea seedlings grown in the soil from CM. This suggests that the soils from remnant church forests, particularly from the canopy under CM, can serve as a good soil origin, which possibly would promote the native tree seedling growth and survival in degraded lands.
