Biochar and saline soil: mitigation strategy by incapacitating the ecological threats to agricultural land

International Journal of Phytoremediation, Journal Year: 2024, Volume and Issue: 26(8), P. 1269 - 1279

Published: Feb. 6, 2024

Soil salinity caused a widespread detrimental issue that hinders productivity in agriculture and ecological sustainability, while waste-derived soil amendments like biochar have drawn attention for their capacity to act as mitigating agent, by enhancing the physical chemical features of soil, contributing recovery agricultural waste resources. However, information concerning which affect physicochemical characteristics soils, crop physiology, growth is limited. To investigate whether mitigates stress on wheat seedlings, we grow them with (120 mM), (20 tons ha−1), its interactive effects. The properties organic carbon (SOC), matter (SOM), dissolved (DOC), available phosphorus (SAP) decreased saline 36.71%, 46.97%, 26.31%, 15.00%, treatment increased SOC, DOC, SAP contents 7.42%, 31.57%, respectively. On other hand, nitrogen (DON) all treatments compared control. root traits, SPAD values, leaf nitrogen, photosynthetic parameters, antioxidant enzymes, reactive oxygen species increasing treatment. Thus, these activities resulted higher leaves biomass alone biochar. According principal component analysis, redundancy mantel test, using conjunction was found be more effective than alone. results this study suggest can used sustainable technique means mitigation agent lowering crops.

Published: Dec. 23, 2023

This study undertook an assessment of 24 physiochemical parameters at over 1094 sites to compute the water quality index (WQI) across upper and central Punjab regions Pakistan. Prior WQI calculation, analytical hierarchy process (AHP) was employed assign specific weights each parameter. The categorization into distinct classes achieved by constructing a pairwise matrix based on their relative importance utilizing Saaty’s scale. Additionally, groundwater status for irrigation drinking purposes various zones in area delineated through integration geostatistical methodologies. findings revealed discernible heavy metal issues Lahore division, with emerging microbiological contamination entire region, potentially attributed untreated industrial effluent discharge inadequately managed sewerage systems. computed indices Lahore, Sargodha, Rawalpindi divisions fell within marginal unfit categories, indicating concerns. In contrast, other were medium class, suggesting suitability purposes. Scenario analysis developing mitigation strategies indicated that primary treatment before wastewater disposal could rehabilitate 9% area, followed secondary (35%) tertiary (41%) treatments. Microbiological (27%) emerged as predominant challenge supply agencies. Given current trajectory deterioration, access potable is poised become significant public concern. Consequently, government agencies are urged implement appropriate measures enhance overall sustainable development.

Food safety has become a serious global concern because of the accumulation potentially toxic metals (PTMs) in crops cultivated on contaminated agricultural soils. Amongst these elements, arsenic (As), cadmium (Cd), chromium (Cr), and lead (Pb) receive worldwide attention their ability to cause deleterious health effects. Thus, an assessment soils, irrigation waters, most widely consumed vegetables Nigeria; Spinach (Amaranthushybridus), Cabbage (Brassica oleracea) was evaluated using inductively coupled plasma-optical emission spectroscopy (ICP-OES). The mean concentration (measured mg kg-1) PTMs soils sequence Cr (81.77) > Pb(19.91) As(13.23) Cd(3.25), exceeding WHO recommended values all cases. This contamination corroborated by pollution evaluation indices. concentrations l-1) water followed similar pattern i.e. Cr(1.87) Pb(1.65) As(0.85) Cd(0.20).

Abstract The paranoid belief that climate change will gradually reduce the ability of world to meet demand for food serves as rationale Nigerian smallholder farmers’ advocacy climate-smart agriculture (CSA) techniques. study investigates effects CSA practice on security status rural farming households in Nigeria. A multi-stage sampling technique was employed selecting 480 across three selected states from Southwest, Data were analyzed using descriptive and inferential statistics. Obtained results showed 59.79% respondents insecure while severe depth among 0.0711 0.1913 respectively. result household dietary diversity score revealed diverse consumption-ability contributions their system. This implies engaged are more likely achieve higher levels consumption score, diversity, security. probit regression significantly influenced by heads’ gender, farm size, contact with extension agents well adopted practices such crop diversification, agroforestry, use Fadama land agricultural activities. research concludes lowered probability insecurity Accordingly, suggests government key players should encourage order ensure sustainability agrarian communities reducing impact change.
