This study examined the effects of biochar and nitrogen fertilizer application on CO2 emissions, microbial communities, soil organic carbon (SOC) in irrigated wheat fields through a 3-year field experiment. Eight treatment groups were established for this study: (1) CK, without or biochar, (2) N1 group, with (300 kg/ha), (3) B (20 t/ha), (4) BN1 application, (5) N2, 15% reduction (255 (6) BN2, + biochar. (7) N3, 30% (210 kg/ha); (8) BN3, The results revealed an increase active (AOC) SOC contents after addition N fertilizer, particularly their combined application. In BN2 treatment, AOC reached 27.48 g/kg 1.47 g/kg, representing increases 3.04% 30.91%, respectively, compared to N1. comparison cumulative emissions increased by 9–48% both possibly due biochar's influence composition functional diversity communities. microbes group differed significantly from that CK (p < 0.01). attributes lower than those BN1, BN3 groups. Furthermore, bulk density biochar-amended was 0.19 g/cm3 untreated CK. Overall, combination dose 255 kg/ha emerged as most effective strategy northern Xinjiang, enhancing content while reducing emissions.

BIOREMEDIATION: A SUPERIOR ALTERNATIVE FOR REMEDIATING TANNERY EFFLUENT-CONTAMINATED SOIL

FUDMA Journal of Sciences, Journal Year: 2025, Volume and Issue: 9(2), P. 193 - 208

Published: Feb. 28, 2025

Tannery effluent poses significant risks to soil health, primarily through contamination with heavy metals like chromium, sulphides, and persistent organic pollutants (POPs). These toxic substances inhibit microbial activity, reducing nutrient cycling matter decomposition essential for fertility. Beneficial microorganisms, including nitrogen-fixing bacteria, are particularly affected, leading altered communities dominated by less advantageous, metal-tolerant species. Accumulation of POPs disrupts enzymatic activities, interferes plant root growth, complicates remediation efforts due pollutant migration groundwater potential entry into the food chain. Prolonged exposure such contaminants diminishes fertility, reduces resilience, ecosystem services, posing threats agricultural productivity environmental health. This review was aimed outline what made bioremediation a superior treatment technology among other methods used in remediating tannery contaminated soil. Efforts mitigate impacts involve combination physical, chemical, biological technologies. Physical washing, flushing, thermal desorption focus on removing or isolating contaminants, while chemical approaches as oxidation, reduction, stabilization transform harmful forms immobilize them. Biological leverages microorganisms plants detoxify sustainably. Bioremediation strategies aid bioaugmentation biostimulation do enhance activity address inorganic effectively more than physical methods. Another excellent called phytoremediation can also effectively, Achieving better technique should be coupled stringent industrial regulations, sustainable tanning methods, stakeholder awareness

Abstract Population and food demand increased rapidly so to face this increment; we must dramatically increase crop production ensure global security. Hence, saline agriculture is a possible solution for producing in salt-affected soils using water irrigation. The objectives of study were investigate the effects applying different types doses biochar soil under irrigation by on quality indicators growth parameters yield arugula plant. Four biochar: banana leaves (BLB), rice straw (RSB), sorghum stalks (SSB), wood chips (WCB) applied pots at levels 1%, 3%, 5% (w/w). This pot experiment was cultivated with (6.2 dS m − 1 ). Total available nitrogen significantly relative control treatment (unamended soil) 41%, 34%, 43%, 33%, 24%, 44% adding 3%WCB, 5%WCB, 1%BLB, 3%BLB, 5%BLB, 5%SSB, 1%RSB, 5%RSB treatments, respectively.

Evaluating biochar’s potential for reducing greenhouse gas (GHG) emissions and increasing crop yields globally is essential to addressing climate change challenges. Analysis of 2140 data pairs from controlled field trials global livestock manure straw raster layers across diverse soils, climates, management practices revealed an average biochar production 1.89 t/ha. Biochar application (BA) increased by 38% reduced GHG 23%. Specifically, with rotary tilling deep (20–50 cm) shows promise, 27% boosting 33%. In terms technologies, the woody deeper soil layer large particle size (> 3 mm) low pyrolysis temperature (200–400°C) can significantly improve yield 42.6% (p < 0.05). High (800–1000°C) small (< surface (0–20 applied reduces 20.5% However, in 32.52% areas there are limitations feedstock resources practical applications, which could make its widespread adoption challenging. Sustainable use support agricultural carbon neutrality, but realizing full benefit will require region-specific policies based on local biomass availability.
