Maize and cowpea are among the staple foods most consumed by of African population, significant importance in food security, crop diversification, biodiversity preservation, livelihoods. In order to satisfy growing demand for agricultural products, fertilizers pesticides have been extensively used increase yields protect plants against pathogens. However, excessive use these chemicals has harmful consequences on environment also public health. These include soil acidification, loss biodiversity, groundwater pollution, reduced fertility, contamination crops heavy metals, etc . Therefore, essential find alternatives promote sustainable agriculture ensure well-being people. Among alternatives, techniques that offer sustainable, environmentally friendly solutions reduce or eliminate inputs increasingly attracting attention researchers. One such alternative is beneficial microorganisms as plant growth-promoting rhizobacteria (PGPR). PGPR provides a variety ecological services can play an role yield enhancers biological control agents. They root development plants, increasing their capacity absorb water nutrients from soil, stress tolerance, disease development. Previous research highlighted benefits using PGPRs productivity. A thorough understanding mechanisms action exploitation biofertilizers would present promising prospect production, particularly maize cowpea, ensuring prosperous agriculture, while contributing security reducing impact chemical environment.

Microbial contribution to the carbon flux in the soil: A literature review

Revista Brasileira de Ciência do Solo, Journal Year: 2024, Volume and Issue: 48

Published: Jan. 1, 2024

ABSTRACT Carbon flows into and out of the soil are important processes that contribute to controlling global climate. The relationship between organisms climate is interdependent since carbon greenhouse gas fluxes simultaneously affected by change management. Temperature, moisture, pH, nutrient level, redox potential organic matter quality key elements affecting microorganisms involved in soil. Climate, topography (slope position landscape), texture, mineralogy land-use regulate those and, thus, C pedosphere. Soil microbes can increase influx storage promoting plant growth, mycorrhizal establishment, particle aggregation. Conversely, efflux from via methanogenesis, rhizospheric activity, mineralization. Nevertheless, strategies management practices could be used balance emissions atmosphere. For example, stimulated growth microorganisms, greater diversity crop rotation cover crops, cultivating mycotrophic plants, avoiding or reducing use fungicides adopting farming, no-tillage systems conservative strategies. Therefore, this review aimed shed light on how influxes soil, its significance for change. Then, we also seek gather practical actions proposed scientific literature improve sequestration In summary, provides a comprehensive basis as helpers lessen increasing fixation agroecosystems stimulation application beneficial microorganisms.
