Abstract BACKGROUND Cereal–legume intercropping provides a solution for achieving global food security, but the mechanism of greenhouse gas emissions and net ecosystem economic benefits maize–soybean relay are poorly understood. Hence, we conducted two‐factor experiment to investigate effects cropping systems, containing (IMS), monoculture maize (M) soybean (S), as well three nitrogen levels at 0 (N0), 180 (N1), 240 (N2) kg N ha −1 on crop grain yield, emissions, soil carbon stock benefit (NEEB). RESULTS The average yield IMS (7.7 t ) increased by 28.5% 242.4% compared with M (6.0 S (2.2 ). land equivalent ratio (LER) was 2.0, which mainly contributed (partial LER: 1.2) rather than 0.8). Although total remarkably enhanced 43.6% 45.5% in N1 N2 contrast N0, LER 37.5% 38.6% lower N0. warming potential (GWP) 11.6% 1.8% corresponding monoculture, resulted from decline GWP organic rate. Moreover, NEEB 133.5% higher (14 032.0 Chinese yuan per year) M, resulting an increase gains cost. A more robust response gain costs inputs led 46.8% 48.3% CONCLUSION Maize–soybean application can obtain advantages without raising environmental costs, approach sustainable agricultural production. © 2024 Society Chemical Industry.

Abstract Aims Bamboo forests represent a unique forest ecosystem, where scientific and rational management is essential for enhancing carbon sequestration ecological functions. Fertilization, as one of the most common crucial practices, significantly influences soil greenhouse gas (GHG) emissions. However, comprehensive multiscale assessment effects different fertilization strategies on these emissions remains limited.Methods A meta-analysis was conducted to quantify impacts various GHG in bamboo forests, utilizing 264 data sets from 44 studies. Additionally, correlation analysis employed examine influence environmental factors emissions.Results Chemical fertilizer (CF) increased CO2 by 21.36% N2O 90.22%, leading 47.01% rise CO2-equivalent Biochar addition (BA) reduced 27.54% despite increasing 15.43%. In contrast, silicate (SIF) decreased 30.33% 42.27%, while low-level nitrogen deposition (ND_L) elevated 19.82% 37.20%, respectively. The combined application biochar chemical (BA + CF) 33.96%. Furthermore, strongly acidic soils (pH < 5.5), enhanced 16.37%.Conclusions conventional rates biochar-based fertilize (BF) SIF can serve effective alternatives traditional fertilizers. emission reduction potential BA, OF BA CF also notable, but excessive should be avoided. such deposition, topography, physicochemical properties

Continuous cultivation of the medicinal herb Codonopsis pilosula ( C. ) declines root yield and active ingredient content. Scientific reasonable intercropping patterns can improve accumulation. However, how systems affect content C.pilosula is still poorly understood. We conducted a field experiment with four treatments, including monoculture (MC), one row faba bean (IC1), two rows (IC2), (IC3), to explore response leaf traits, yield, cropping patterns. The results showed that significantly increased by 7.0-18.7%, lobetyolin 8.6-25.2%, atractylenolide III 34.2-54.0%, syringin 31.1-53.4% compared monoculture, largest advantage occurred in IC2. also improves size, net photosynthetic rate, C metabolism enzyme activity . Correlation analysis partial least squares path model improved be attributed enhanced photosynthesis metabolism, indicating appropriate configuration /faba system could increase enhancing light use efficiency. These findings suggest promising approach establishing high-yield sustainable agroecosystem.

Incorporating crop residues into the soil is an effective method for improving carbon sequestration, fertility, and productivity. Such potential benefits, however, may be offset if residue addition leads to a substantial increase in greenhouse gas (GHG) emissions. This study aimed quantify effect of different with varying C/N ratios nitrogen (N) fertilizers on GHG emissions, yield, yield-scaled emissions (GHGI) winter wheat. The field experiment was conducted during 2018–2019 wheat season, comprising four treatments (no residue, maize soybean maize-soybean mixed residue) fertilizer (control, urea, manure, manure + urea). followed randomized split-plot design, N as main plot factor sub-plot factor. Except control, all received 150 kg ha−1 season−1. results showed that soils from acted net source N2O CO2 fluxes but sink CH4 fluxes. Soybean significantly increased while had lowest among three residues. However, amendments Furthermore, grain yield by 24% 21%, respectively, compared no amendment. Both reduced GHGI 25% residue. Additionally, urea exhibited higher treatments, they contributed yields resulted lower GHGI. Moreover, incorporation altered dynamics. In residue-amended soil, both NH4+ NO3− concentrations were (p < 0.05). Conversely, content notably Overall, our findings contribute comprehensive understanding how additions cropping systems influence dynamics offering valuable insights agroecosystems management long-term food security sustainability mitigating
