Phosphorus recovery through enhanced biological phosphorus removal (EBPR) processes from agricultural wastes holds promise in mitigating the impending global P shortage. However, complex nutrient forms and microbial augments, expected to exert a profound impact on crop rhizomicrobiome thus health, remained unexplored. In this study, we investigated impacts of EBPR biosolids crops growth comparison chemical fertilizer Vermont manure compost. Our findings revealed that biosolid augmentation promoted best maize shoot traits with least deficiency, evidencing its benefits. Biosolid significantly impacted decreased biodiversity but higher activities enriched taxa capable utilizing various carbon sources. The novel single-cell Raman spectroscopy phenotyping technique uncovered surprisingly high abundance (up 30%) polyphosphate-accumulating organisms (PAOs) rhizosphere their distinctive variations different amendments. Furthermore, interactions between EBPR-derived PAOs such as Candidatus Accumulibacter phosphatis soil native plant promoting rhizobacteria highlighted previously overlooked status yet-to-be-characterized functions cycling.

Drought generates a complex scenario worldwide in which agriculture should urgently be reframed from an integrative point of view. It includes the search for new water resources and use tolerant crops genotypes, improved irrigation systems, other less explored alternatives that are very important, such as biotechnological tools may increase efficiency. Currently, large body evidence highlights role specific strains main microbial rhizosphere groups (arbuscular mycorrhizal fungi, yeasts, bacteria) on increasing drought tolerance their host plants through diverse plant growth-promoting (PGP) characteristics. With this background, it is possible to suggest joint distinct PGP microbes could produce positive interactions or additive beneficial effects if co-inoculation does not generate antagonistic responses. To date, have only been partially analyzed by using single omics tools, genomics, metabolomics, proteomics. However, there gap information multi-omics approaches detect between plants.

Acid soils occupy approximately 50% of potentially arable lands. Improving crop productivity in acid soils, therefore, will be crucial for ensuring food security and agricultural sustainability. High soil acidity often coexists with phosphorus (P) deficiency aluminum (Al) toxicity, a combination that severely impedes growth yield across wide areas. As roots explore the nutrients water required plant development, they also sense respond to below-ground stresses. Within terrestrial context widespread P Al toxicity pressures, plants, particularly roots, have evolved variety mechanisms adapting these legumes, soybean (Glycine max) plants may acquire nitrogen (N) through symbiotic fixation (SNF), an adaptation can useful mitigating excessive N fertilizer use, either directly as leguminous participants rotation intercropping systems, or secondarily green manure cover crops. In this review, we investigate especially soybean, recent advances our understanding root-based linked root architecture modification, exudation symbiosis, together associated genetic molecular strategies individual and/or interacting conditions soils. We propose breeding legume cultivars superior nutrient efficiency tolerance traits selection might become powerful strategy producing varieties capable maintaining improving yields more stressful subjected increasingly challenging environmental conditions.
