Sub-Saharan Africa (SSA) faces chronic food insecurity associated with soil degradation and the peculiar aftermath of climate change exacerbated by rising population historically poor agricultural practices. Notably, use mineral fertilizers has potential to counteract in SSA; it drives an increased production required feed while sustaining quality health soils. However, limited financial resources deprive SSA promise fertilizers, wherein application rates are low, regimes characterized unbalanced nutrient composition fertilizer quality. Although current global is generally low efficiency, most affected due already usage available products. About 70% fertilizer-nitrogen lost through unregulated transformation ammonia, nitrous oxide, nitrate that either volatilized or emitted into atmosphere leached water bodies. Similarly, preponderance fertilizer-phosphorus via run-off leaching, unavailing plants overloading streams rivers and, together nitrate, causing eutrophication. These environmental problems accentuated where quantity issues a limiting factor. recent advances happening outside indicate nutrients, when strategically formulated, such as nano packaging, (bio)polymer encapsulation, tunable respond cues, can provide multiple outcomes, particularly, healthy soils higher productivity. Therefore, presumably, proper synthesis gamut properties influencing plant release availability, options for exposure uptake critical realizing these benefits SSA. Despite possibilities, there lack deeper context on fertilizer-related they affect nutrition security This paper provides overview fertilizer-nutrient agronomic, challenges opportunities, which though not exclusive per se, be reasoned peculiarity region. impetus increase improve health, sustainable crop production,

Inoculation of phosphate-solubilizing bacteria improves soil phosphorus mobilization and maize productivity

Nutrient Cycling in Agroecosystems, Год журнала: 2023, Номер 126(1), С. 21 - 34

Abstract Phosphate-solubilizing bacteria represent a bioalternative in making soil-immobilized phosphorus (P) available to plants, and consequently improve agriculture sustainability reduce nutrient pollution. In this study, we examined whether Rhizobium sp. B02 inoculation can affect the soil P fractions. Moreover, investigated how influences growth, physiological traits, productivity of maize crop. Field tests were carried out evaluate combined application strain reduced doses fertilizer. Soil fractionation was performed after crop harvesting, assessing dynamics. To study plant response, samplings three phenological stages—the vegetative stage 7 fully emerged leaves with leaf collars (V7), tassel (VT), reproductive maturity (R6). Using 50% fertilizer recommended, increased labile inorganic fraction by 14% compared control treatment at same dose, indicating that it favored Pi mobility. Under these conditions V7 VT stages, significantly improved shoot length (28 3%) dry weight (9.8 12%). grain yield 696 kg ha −1 using recommended rate fertilizer, phenocopying complete fertilization without inoculation. Therefore, replaced availability.

Changes in phylogenetic structure and species composition of woody plant communities across an elevational gradient in the southern Taihang Mountains, China

Global Ecology and Conservation, Год журнала: 2023, Номер 42, С. e02412 - e02412

Understanding community assembly mechanisms along the geographical gradients is of great importance in ecological research. The Taihang Mountains are intersection north and south flora, with abundant species complex structures, which provide multiple services. However, phylogenetic structure composition woody plants still not very well understood. In this study, 35 forest dynamic plots were established natural distribution areas from 850 to 1850 m above sea level. We explored pattern elevational change communities influencing factors using regression analysis, correlation principal coordinate analysis. Our results displayed that both net relatedness (NRI) nearest taxon (NTI) values at most within random confidence intervals (−1.96 1.96). Meanwhile, a significant negative existed between gradient (NRI: r = −0.61, p < 0.05; NTI: −0.57, 0.05). That is, elevation increasing, tended be overdispersed. Furthermore, was only significantly affected by soil total nitrogen (p 0.05) multi-stepwise Above all, these illustrated assemblages plant mainly influenced neutral process environmental filtering.

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

Revista Brasileira de Ciência do Solo, Год журнала: 2024, Номер 48

Опубликована: Янв. 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.

Comparative Analysis of Plant Growth-Promoting Rhizobacteria (PGPR) and Chemical Fertilizers on Quantitative and Qualitative Characteristics of Rainfed Wheat

Agronomy, Год журнала: 2022, Номер 12(7), С. 1524 - 1524

Опубликована: Июнь 25, 2022

The indiscriminate use of hazardous chemical fertilizers can be reduced by applying eco-friendly smart farming technologies, such as biofertilizers. effects five different types plant growth-promoting rhizobacteria (PGPR), including Fla-wheat (F), Barvar-2 (B), Nitroxin (N1), Nitrokara (N2), and SWRI, their integration with (50% and/or 100% need-based N, P, Zn) on the quantitative qualitative traits a rainfed wheat cultivar were investigated. Field experiments, in form randomized complete block design (RCBD) four replications, conducted at Qamloo Dryland Agricultural Research Station Kurdistan Province, Iran, three cropping seasons (2016–2017, 2017–2018, 2018–2019). All investigated characteristics significantly affected integrated application PGPR fertilizers. grain yield treated plants F, B, N1, N2 plus 50% was increased 28%, 37%, 33%, respectively, compared noninoculated control. Compared control, protein content 0.54%, 0.88%, 0.34% through fertilizers, respectively. A combination best treatment to increase (56%) (1%) Azar-2 cultivar. results this 3-year field study showed that nutrient management PGPR-need-based Zn considered crop tactic quality reduce fertilization subsequent environmental pollution could useful terms sustainable production.
