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.

Reducing greenhouse gas (GHG) emissions from agricultural fields is crucial for mitigating climate change and promoting sustainable agriculture. This study conducted a meta-analysis of 82 domestic experimental studies to assess the effects fertilization, tillage, straw return on CH4, CO2, N2O across different regions in China. The key findings include: fertilization measures: split increased CH4 emissions, whereas single application had strongest impact CO2 emissions. carbon alone or combination with NPK reduced GHG while nitrogen farmyard manure significantly Tillage tillage generally but No-tillage effectively suppressed rotary Straw return: returning through led highest increase direct most notably enhanced provides insights into optimizing practices mitigate offers guidance low-carbon development.

Greenhouse Gas Emission, Carbon Footprint and the Ecosystem Carbon Budget of Sorghum Production: Replacing Chemical Fertilizer with Partial Manure in Saline Soils

Опубликована: Янв. 1, 2025

Excessive long-term application of synthetic nitrogen has resulted in serious environmental issues vulnerable ecosystems and contributed to global warming. The partial replacement N fertilizer with manure croplands provides an alternative agronomic strategy mitigate pressure on the ecological environment. Therefore, this study, we aimed evaluate effects longer-term substitution soil greenhouse gas emissions, carbon footprint (CF), budget. To end, established four treatments: no (control, N0), chemical (180 kg ha-1, N180), replaced aged cow at ratios 40% (OS40) 60% (OS60). Each treatment was applied sorghum under drip irrigation plastic mulching over two growing seasons. Greenhouse topsoil organic storage, CF, budget, were assessed using life cycle assessments balance calculations. results showed that, compared N180, OS40 OS60 increased cumulative CO2 indirect CO2-eq emissions reduced N2O CH4 emissions. Soil storage net primary productivity significantly enhanced those whereas these variables not different between OS60. ecosystem budget increasing ratio. A (108 ha-1 inorganic fertilizer, 72 fertilizer) selected as a suitable candidate for reducing CF promoting enrichment salt-affected soils.

Effects of Tillage Practices on Soil Properties and Maize Yield in Different Types of Soda Saline–Alkali Soils

Agriculture, Год журнала: 2025, Номер 15(5), С. 542 - 542

Опубликована: Март 2, 2025

The implementation of scientific cultivation practices on soda saline–alkali land plays a pivotal role in safeguarding food security and promoting sustainable agro-economic development at the regional scale. However, there exists critical knowledge gap regarding optimization tillage strategies for rain-fed maize (Zea mays L.) across heterogeneous soil matrices. This study selected meadow alkaline soil, saline mild under typical micro-landscape morphological characteristics Songnen Plain as experimental plots. Under three methods, namely no (NT), rotary + (RT), subsoiling (SRT), effects methods physical properties seedling stage, root V6 yield R6 stage during process cultivating different types soils were analyzed. research results showed that compared with NT RT, SRT treatment better improved properties, such penetration resistance bulk density micro-spaces (0–40 cm), types. had positive impact seedlings soil. In terms yield, treatment, effect plant height, dry weight, 1000–grain grain maize. increases 27.94% 13.24%, respectively. Compared NT, differences RT treatments saline-alkali smallest, being 6.98% 4.77%, relevant provide guidance theoretical basis improving increasing yield.
