Abstract Role of varying C:N ratios biochar to enhance soil health and impacts across types remain inadequately understood. Therefore, this study aimed elucidate the mechanisms change in organic carbon (SOC) fractions greenhouse gas (GHG) emissions under nitrogen‐enriched (NB) application sandy loamy soil. A control (CK; without biochar) four types, including one pristine (PB) three NB (NB1, NB2, NB3), were applied at two rates (20 t ha −1 [L1] 40 [L2]). Biochar levels significantly influenced CH₄ CO₂ emissions. effectively reduced while increased both types. enhanced SOC pools, which is primarily attributed mineral‐associated particulate soils. β‐glucosidase, cellobiohydrolase, β‐xylosidase by NB, particularly a higher rate (L2) compared CK, with more pronounced increases Structural equation modeling showed that SOC. The results provide valuable insights for guiding applications reducing improving fertility, potential benefits diverse agroecosystems farming communities worldwide.

Effects of Biochar on Soil Organic Carbon Stability in Degraded Alpine Grasslands—A Study on Arid Regions in Central Asia

Land, Год журнала: 2025, Номер 14(5), С. 1018 - 1018

Опубликована: Май 7, 2025

Numerous studies have reported the importance of soil organic carbon (SOC) in grassland ecosystems and its response to degradation, but effect biochar application on SOC pools degraded alpine grasslands remains unclear. Here, we set up nine addition treatments with a combination three different particle sizes (0~0.25 mm, 0.25~1 1~2 mm) additions (1%, 2%, 4%), conducted short-term observational experiment over 7-month period non-degraded (ND), lightly (LD), severely (SD) zones grassland. The results showed that mm/2% mm/4% increased storage LD SD by 2.03 kg m−2 1.19 m−2, respectively. decreased stability pools, time. structural equation modeling (SEM) indicated changes size would indirectly affect influencing plant indicators, while electrical conductivity (EC) were key factors grasslands. These can provide technical support theoretical basis for realizing benign development “carbon neutral” strategy arid areas.

Machine Learning Predicted Crop Yield and Soil Organic Carbon Variation After Biochar Application

Soil Use and Management, Год журнала: 2025, Номер 41(2)

Опубликована: Апрель 1, 2025

ABSTRACT The prediction of crop yield is significant interest for growers utilising biochar on land, while managers prioritise the enhancement soil organic carbon (SOC). However, it remains unclear to what extent machine learning can accurately predict or SOC when applied soil. In this study, Random Forest (RF) and Multilayer Perceptron Neural Network (MLP‐NN) models were employed with 297 paired data from field trials. results indicated that RF model (test R 2 = 0.83) did not differ significantly MLP‐NN 0.84) in predicting yield. 0.87) performs better than 0.53) SOC. most influential features found be application rate (15%), initial (13%), pH (10%), TP (10%). contrast, variation was primarily influenced by latitude (26%), (22%), (13%). Furthermore, both multiple factors, solely one, their impacts necessarily linear. This study suggests optimization phosphorus content, along regulation its sandy clay‐rich soils, simultaneously enhance future, we hope develop a decision support system prediction, different scenarios, consultation capabilities based geospatial location.

Опубликована: Окт. 3, 2024

Biochar application is an effective way to improve soil organic carbon (SOC) content and ensure food security. However, there were differences in SOC following biochar under different conditions. We collected 637 paired comparisons from 101 articles determine the following: (1) average effect of on (2) response nutrient contents, climate zones cropping systems application. The results showed that available phosphorus (P) potassium (K) reached highest level category <10 mg kg−1 >150 kg−1, respectively. Soil total P subgroups achieved maximum increase intermediate category. Cw zone (temperate, without dry season) obtained content. Compared with plough tillage, rotary tillage presented significantly higher Therefore, low K moderate N more increasing Furthermore, a random forest algorithm contents most important variables. This study provided scientific basis for sequestration improving fertility.

Increases in near-surface ozone (O3) concentrations is a global environmental problem. High-concentration O3 induces stress plants, which can lead to visible damage reduced photosynthesis, accelerated aging, inhibited growth, and even plant death. However, its impact has not been comprehensively evaluated because of the response differences between individual species, concentration, duration plants. We used meta-analysis approach based on 31 studies 343 observations) examine effects elevated malondialdehyde (MDA), superoxide dismutase (SOD), peroxidase (POD) activities herbaceous Globally, important as they constitute majority world's food crops. partitioned variation effect size found according presence species (ornamental herb, rice, wheat), Our results showed that membrane lipid peroxidation depending The wheat SOD POD activity was significantly lower compared herbs rice (P<0.01). all plants increased by 34.6%, 10.5%, 26.3% for exposure times environments 1-12, 13-30, 31-60 days, respectively.

The pollution caused by plastic mulch film in agriculture has garnered significant attention. To safeguard the ecosystem from detrimental effects of pollution, it is imperative to investigate use biodegradable materials for manufacturing agricultural film. Biochar emerged as a feasible substance production (BDM), providing soil benefits. Although biochar been widely applied BDM manufacturing, effect biochar-filled on carbon stock after its degradation not well documented. This study provides an overview current stage incorporated with and summarizes possible pathway contribution. application biochar-incorporated can lead substantial changes microbial diversity, thereby influencing emissions greenhouse gases. These alterations may ultimately yield unforeseen repercussions cycles. However, light knowledge vacuum potential challenges, additional necessary ascertain if effectively mitigate issues residual microplastic contamination land. Significant progress remains before fully supplant traditional production.
