Biochar is a stabilised, carbon-rich material created when biomass heated to temperatures usually between 450 and 550 °C, under low-oxygen concentrations. This study evaluated the effectiveness of sawdust, cocoa pod ash rice husk biochars in remediating metal-contaminated paddy soil Nobewam, Ghana. was applied 21 days before cultivating for 120 days, followed by sampling harvesting metals physicochemical analyses. Compared untreated soils, biochar treatments exhibited an enhancement quality, characterised increase pH 1.01–1.20 units, available phosphorus (P) concentration 6.76–13.05 mg/kg total nitrogen (N), organic carbon (OC) concentration, ranging from 0.02% 0.12%. Variabilities electrical conductivity effective cation exchange capacity were observed among treated soils. Concentrations potentially toxic (arsenic, cadmium, copper, mercury, lead zinc) soils analysed atomic absorption spectroscopy showed significant differences (p < 0.05) sampled The concentrations arsenic all samples exceeded Canadian Council Ministers Environment quality guideline agricultural with having highest levels Cadmium had potential ecological risk index > 2000 geoaccumulation above 5, indicating pollution samples. In contrast, mercury contamination only found Among tested treatments, its combinations, particularly ash, efficacy reducing metal non-carcinogenic human health risks associated consumption grown biochar-treated lower compared control Future research should focus on long-term field studies validate these findings explore underlying mechanisms governing immobilization fields.

For agricultural production is used almost 40% of the global land from where it dominates conventional agriculture which uses large amounts inputs in form fertilizers and pesticides leading to contamination soil, water resources, air pollution erosion, affects biodiversity extinction many plants animals. On other hand, world's population constantly growing currently numbers more than 8 billion people estimated that food will have double by 2050. In order meet future needs for raw materials, must significantly increase, at same time, impact on environment natural resources be drastically reduced. Sustainable emerging as one solutions. This way practice refers management preservation through organizational technological changes modern satisfy human preserve environment. One most important entire relies land. intensively cultivated lands, there a noticeable trend intense degradation, represents major problem facing humanity. The paper reviews decrease soil fertility based samples collected during five-year monitoring, well proposal measures increase this environmental resource.

The combined application of biochar and fertilizer has become increasingly popular for improving soil quality crop productivity. However, the reported research results regarding effects on properties productivity have contradictory findings, indicating requirement further scientific research. Therefore, this study aimed to investigate a water hyacinth (WHB) NPS physicochemical wheat yield under deficit irrigation conditions in acidic silty loam Ethiopia. Four different rates (0, 5, 10, 20 t ha−1), three 100, 200 kg two regimes (50 100% requirement) were evaluated assess yields. showed that amendment significantly reduced bulk density by 15.1–16.7%, improved porosity 6.8–8.6% moisture content 10.3–20.2%. Additionally, pH (0.26–0.87 units), NH4+–N (73.7–144%), NO3−–N (131–637%), available phosphorus (85.8–427%), compared alone. As result, dry biomass grain increased 260 173%, respectively. Furthermore, WHB resulted comparable even with 50% reduction water. significant potential improve when it is applied combination fertilizer, can reduce production.

Maize is an important cereal in many developed and developing countries of the world. One primary challenges for maize cultivation soil acidity. Acidic a major constrain achieving food security requiring sustainable solutions. Biochar, pyrogenic carbon-rich material, carries reactive surfaces (i.e., high surface area variable charges). Therefore, it facilitates nutrient retention gradual release to plants, thereby supporting crop growth. However, combine effects functionalized biochar with microbes on phosphorus (P) bioavailability plant performance remain unclear. This study investigates application different oxidized biochars (i.e.,fresh rice husk (RHB), pH adjusted RHB control) phosphate solubilizing bacteria <em>Pseudomonas aeruginosa</em>, properties including dynamics grown acid soil. Biochar was using 10% hydrogen peroxide while 8.5. pots having 20 kg or soil-biochar mixture. Overall, treatments increased yield greater giving significant × interactions. Specifically, when applied aeruginosa</em> P availability by 380 % which then contributed increment (291%). We also observed reduction available aluminum (Al) concentration (40% ) compare control. These improvement might have occurred due increase pH, (r<sup>2</sup>= 0.74), Al toxicity 0.36).Findings this could implications production acidic

Global agricultural challenges, especially soil degradation caused by abiotic stresses, significantly reduce crop productivity and require innovative solutions. Biochar (BC), a biodegradable product derived from forestry residues, has been proven to enhance quality. Although its benefits for improving properties are well-documented, the potential of BC mitigate various stresses-such as drought, salinity, heavy metal toxicity-and effect on plant traits need further exploration. This review aims elucidate production highlighting primary feedstock's synthesis techniques, examining role in boosting decomposition efficiency fertility, which pivotal sustainable growth. also discuss how can nutritional chemical under different stress conditions, emphasizing capacity foster growth development adverse environments. Furthermore, this article serves comprehensive resource researchers understanding importance promoting agriculture, addressing environmental challenges. Ultimately, highlights critical knowledge gaps proposes future research avenues bio-protective against paving way commercialization applications large scale with cutting-edge technologies.

Phosphorus (P) is an essential element for life on earth and a limiting nutrient plant growth. However, its availability in saline-alkaline soils significantly reduced, adversely affecting productivity. Saline-alkaline soil widespread problem that severely affects growth The Parthenium-derived biochar (PB) Sewage sludge-derived (SSB) were analyzed pH, electric conductivity (EC), cation exchange capacity (CEC), calorific values (CV), surface area (SSA). phosphate solubilizing index (SI; 2.83 mM) quantitative analysis (521.5 µg ml-1) suggested PSB-01 efficient the strain identified through 16S rRNA sequencing techniques. experiment was based completely randomized block design (CRBD) with triplicates. results revealed application of PB, SSB, improved Spinacia oleracea (S. oleracea) as compared to control. highest observed combined amendments single once both 1% 3%. reduction anion concentrations applications SSB along can enhance properties (pH, CEC, SSA anoins cations) promote growth, offering sustainable solution agricultural soil. This study employs innovative approach by combining biochars derived from Parthenium sewage sludge phosphate-solubilizing bacteria (PSBs) address multiple issues simultaneously: mitigating soil, controlling overgrowth, managing problems.
