Abstract Background The rhizosheath, a cohesive soil layer firmly adhering to plant roots, plays vital role in facilitating water and mineral uptake. In pearl millet, rhizosheath formation is genetically controlled influenced by root exudates. Here, we investigated the impact of exudates on microbiota composition, interactions, assembly processes, structure millet using four distinct lines with contrasting aggregation abilities. Results Utilizing 16S rRNA gene ITS metabarcoding for...

Current agricultural practices rely heavily on synthetic fertilizers, which not only consume a lot of energy but also disrupt the ecological balance. The overuse fertilizers has led to soil degradation. In more sustainable approach, alternative methods based biological interactions, such as plant growth-promoting bacteria (PGPRs), are being explored. PGPRs, include both symbiotic and free-living bacteria, form mutualistic relationships with plants by enhancing nutrient availability,...

Abstract Reducing the deleterious effects of intensive tillage and fertilization on ecosystem integrity human health is challenging for sustainable agriculture. The use cover crops has been advocated as a suitable technique this purpose, but scientific evidence to support scarce. After four years complete rotation, including wheat, maize, green pea main in ploughing system, we investigated respective combined nitrogen soil chemical biological properties using controlled experiment combining...

Abstract Soil fertility and productivity are severely impacted by exploitation degradation processes. These threats, coupled with population growth climatic changes, compel us to search for innovative agroecological solutions. Prebiotics, a type of soil biostimulant, used enhance conditions plant may play role in carbon (C) sequestration. Two commercial prebiotics, K1® NUTRIGEO L® (referred as SPK SPN, respectively), were assessed their effects on agricultural cultivated Zea mays L.,...

Prebiotics, a subset of biostimulants, have garnered attention for their potential to enhance soil conditions and promote plant growth, offering promising alternative conventional agricultural inputs. This study explores how two commercial prebiotics, K1® NUTRIGEO L® (SPK SPN), impact functions compared control (SP). The experiment involved amended with organic wheat straws cultivated Zea mays L. Previous research demonstrated substantial effects these prebiotics on biomass, parameters,...
