Biodegradable film (BF), as a superior substitute for traditional polyethylene (PF), has experienced consistent increase in China. However, significant research gap persists regarding the utilization of BF assessing farmland carbon balance. This experiment examined responses maize growth, yield, irrigation water productivity (IWP), CO2 emissions, and field net sequestration (NCS) to two types (BF1, 100-day induction period, BF2, 80-day period), PF, three amounts (I1, I2, I3: 5250, 5625, 6000 m3 ha–1), by conducting two-year (2019–2020) trial typical arid semi-arid region The results indicated that biodegradable mulching (BFM) negatively affected resulting reduced yield IWP. Especially under I1 level, 6.26%–13.99% IWP 6.64–13.85%. Notably, I2 BF1 had comparable impact on PF. Additionally, exerted more pronounced promoting effect total biomass than Concerning balance, short-term application resulted emissions (5.74–6.30% 9.27–12.37% BF2), without any NCS cropland. Taking into account economic value ecology, we recommended utilizing 5625 ha–1 areas, while opting with longer period whenever feasible.

Climate change caused by increasing greenhouse gas (GHG) emissions has led to frequent extreme weather events, which seriously threaten sustainable agricultural production. Therefore, it is essential optimize proper irrigation management improve the grain yield, crop water productivity (WPc), economic (EWPc), and lower global warming potential (GWP) GWP Intensity (GWPI). The effect of scheduling methods on GHG remains largely unknown, even though this knowledge management. To address gap, a field experiment was carried out in North China Plain (NCP) for three winter wheat seasons measure influence different WPc, EWPc, GWP, GWPI. Irrigation including 50%, 60%, 70% capacity (FC) were kept main plots methods, sprinkler, drip, flood sub-plots. results revealed that relative sprinkler at 60% FC, drip FC significantly (p < 0.05) improved yield 4.89–7.52%, WPc 1.0–5.4%, EWPc 1.1–5.49%, 7.47–9.34%, GWPI 10.92–15.23%. Compared with increased 5.34–6.81%, 5.65–15.1%, 5.73–15.12%, 10.36–15.16%, 16.22–19.40%. Technique order preference similarity an ideal solution (TOPSIS) presented compared scheduling, provides best optimal balance combined suggested sustained mitigated NCP.

Abstract Prediction of carbon dioxide (CO 2 ) emissions from agricultural soil is vital for efficient and strategic mitigating practices achieving climate smart agriculture. This study aimed to evaluate the ability two machine learning algorithms [gradient boosting regression (GBR), support vector (SVR)], deep [feedforward neural network (FNN) convolutional (CNN)] in predicting CO Maize fields agroclimatic regions i.e., continental (Debrecen-Hungary), semi-arid (Karaj-Iran). research developed three scenarios .

Abstract Agricultural activities have been expanding globally with the pressure to provide food security earth's growing population. These agricultural profoundly impacted soil organic carbon (SOC) stocks in global drylands. However, effects of clearing natural ecosystems for cropland (CNEC) on SOC are uncertain. To improve our understanding emissions and sequestration under different land uses, it is necessary characterize response patterns types CNEC. We conducted a meta‐analysis mixed‐effect model based 873 paired observations croplands adjacent from 159 individual studies Our results indicate that CNEC significantly ( p < .05) affects stocks, resulting combination clearing, management practices (fertilizer application, crop species, cultivation duration) significant negative initial stocks. Increases (in 1 m depth) were found which previously (deserts shrublands) had low increases 278.86% (95% confidence interval, 196.43%–361.29%) 45.38% (26.53%–62.23%), respectively.

Abstract The management of biowaste and agricultural solid waste is gaining attention due to rising landfill disposal costs the need for locally available feedstocks. biorefinery concept aims achieve zero through valorizing residues as fertilizers. Despite containing NPK macronutrients, may not promote plant growth limited nutrient availability phytotoxic compounds. production valuable organic, mineral-organic, or mineral fertilizers with confirmed agronomic properties marketable products remains understudied. This comprehensive review broadens our understanding fertilizer in biorefineries, which complements energy (thermal, biogas, biodiesel) chemical compounds (e.g., succinic acid, propanediol, protein concentrates) that are also generated within biorefineries. It among first reviews investigate importance fertilizers, emphasizing methods leading commercial rationale behind this process. findings confirm directly applying unprocessed soil does fully exploit their value by-products. study contributes practical analysis barriers (legal, chemical, biological, technological) opportunities (rising prices reduced global fertilizers) related biorefining
