Biochar is a versatile and sustainable tool for agricultural environmental remediation due to its unique physicochemical properties in terms of soil fertility, nutrient retention, water holding capacity. As stable carbon-rich material, biochar promotes plant growth increases crop yields by enhancing microbial activity. It can also be used as sorbent removing pollutants such heavy metals, organic contaminants, nutrients from systems. However, the utility ecological impact affected combined effects many variables. This paper discusses application on potential mitigate various challenges composition, augmenting accessibility, part efforts promote agriculture based recent findings. These findings are expected improve farming while contributing mitigation climate change diverse routes (e.g., sequestering atmospheric carbon, improving quality, reducing greenhouse gas emissions). offers promising opportunity help harness power pave way more resilient future.

Biochar Input to Saline-Alkali Farmland Can Improve Soil Health and Crop Yield: A Meta-Analysis

Agriculture, Год журнала: 2025, Номер 15(5), С. 561 - 561

Soil salinization in farmland is a critical factor limiting global soil health, food security, and ecosystem productivity. Biochar has recently shown great application potential agricultural fields many domains, such as structure improvement, carbon sequestration, reductions greenhouse gas emissions. Here, meta-analysis of 113 published papers was carried out to quantify the effects biochar on remediation saline-alkali crop yield terms climatic conditions management, with aim determining optimal management strategy for soils. The results show that adding increases TOC (44.0%) water utilization efficiency (8.7%), decreases salinity (−9.6%), certain salt ion contents particular (Na+, 12.5%; Cl−, 23.4%; HCO3−, −17.7%), along pH (−2.2%), resulting 20.8% higher yield. Applying shell at rate 10–20 t·ha−1 monoculture most promising way bolster severely irrigated farmland. However, raises CO2 CH4 emissions by 9.8% 31.6%, respectively, but lowers emission N2O 29.4%. These findings provide scientific recommendations sustainable areas worldwide.

Impacts of Climate Change and Agricultural Practices on Nitrogen Processes, Genes, and Soil Nitrous Oxide Emissions: A Quantitative Review of Meta-Analyses

Agriculture, Год журнала: 2024, Номер 14(2), С. 240 - 240

Опубликована: Фев. 1, 2024

Microbial-driven processes, including nitrification and denitrification closely related to soil nitrous oxide (N2O) production, are orchestrated by a network of enzymes genes such as amoA from ammonia-oxidizing bacteria (AOB) archaea (AOA), narG (nitrate reductase), nirS nirK (nitrite nosZ (N2O reductase). However, how climatic factors agricultural practices could influence these processes and, consequently, N2O emissions remain unclear. In this comprehensive review, we quantitatively assessed the effects on nitrogen using mega-analysis (i.e., meta-meta-analysis). The results showed that global warming increased rates, leading an overall increase in 159.7%. Elevated CO2 stimulated both with substantial emission 40.6%. Nitrogen fertilization amplified NH4+-N NO3−-N contents, promoting AOB, nirS, nirK, caused 153.2% emission. application biochar enhanced AOA, nosZ, ultimately reducing 15.8%. Exposure microplastics mostly process 140.4%. These findings provide valuable insights into mechanistic underpinnings microbial regulation emissions.

Soil contaminants may restrict soil functions. A promising remediation method is amendment with biochar, which has the potential to both adsorb and improve health. However, effects of biochar on soil-plant nitrogen (N) dynamics N cycling microbial guilds in contaminated soils are still poorly understood.
