Summary: Long-term excessive nitrogen application in sweet maize farmland in China has caused significant greenhouse gas and reactive nitrogen emissions. This study compared the effects of replacing nitrogen fertilizer with cow manure at different ratios on crop yield, gas emissions, soil organic carbon concentration, and carbon and nitrogen footprints. The results showed that replacing 20% of the nitrogen fertilizer with cow manure can reduce N2O emissions and increase soil organic carbon concentration while increasing greenhouse gas emissions and intensity. However, replacing 50% of the nitrogen fertilizer led to decreased crop yield and increased gas emissions and intensity. This study provides a research basis for developing a sustainable sweet maize farming system in the region and has implications for clean agricultural production in subtropical areas.

Summary: Intercropping maize and peas can improve soil health and increase carbon storage, especially when reducing nitrogen fertilizer inputs. An 11-year long-term experiment showed that intercropping increased soil organic carbon concentration and stock, reduced bulk density, and decreased greenhouse gas emissions. This environmentally-friendly farming strategy plays a crucial role in soil quality and carbon sequestration.

Summary: This study investigated the effects of maize-soybean intercropping on nitrogen uptake, yield, utilization efficiency, and nitrogen assimilatory enzymes of maize crops under different nitrogen fertilization conditions. The results showed that intercropping at the optimal nitrogen rate significantly increased maize grain yield, residue yield, and 100-grain weight in both years. Intercropping also improved nitrogen content and uptake, as well as the activities of nitrogen assimilatory enzymes. These findings highlight the potential of intercropping for enhancing nitrogen status and use efficiency in maize crops, supporting sustainable agricultural production.

Summary: This study conducted field observation experiments for three years to compare the comprehensive benefits of different film mulching irrigation methods on greenhouse gas emissions, grain yield, water and fertilizer efficiency in maize fields. The results showed that drip irrigation under mulch (DM) had lower N2O emissions (32.46%), higher CH4 absorption (23.49%), and lower CO2 emissions (4.53%) compared to border irrigation under mulch (BM). Different environmental factors played varying roles in controlling greenhouse gas fluxes under the two treatments. Maize yield, irrigation water use efficiency (IWUE), and partial factor productivity of applied nitrogen (PFPN) were higher under DM by 17.85%, 17.90%, and 71.84% respectively, while the global warming potential (GWP) and greenhouse gas emission intensity (GHGI) under DM were lower by 6.65% and 20.79% respectively compared to BM. This research provides valuable insights into agricultural development in arid areas.

Summary: This study aimed to investigate the impact of different levels of biochar (BC) and nitrogen (N) application on the performance of maize-soybean intercropping system. The results showed that the treatment of 15 t ha(-1) BC and 180 kg ha(-1) N increased grain yield and water use efficiency (WUE), while 15 t ha(-1) BC and 135 kg ha(-1) N enhanced nitrogen recovery efficiency (NRE) in both years. However, nitrogen promoted the protein and oil content of intercropped maize, but decreased the protein and oil content of intercropped soybean. Moreover, BC did not improve the protein and oil content of intercropped maize, but increased maize starch content. BC had no positive impact on soybean protein, but it unexpectedly increased soybean oil content. The comprehensive assessment value first increased and then declined with increasing BC and N application. These findings provide a comprehensive understanding of the growth of maize-soybean intercropping system and its potential to enhance production in northeast China.

It was found that intercropped maize soils had increased complexity and robustness of soil networks, while densities of plant parasitic nematodes and β-glucosidase activity were reduced. Intercropped soybean soils had lower C availability, but showed an increase in saprophytic fungi and plant parasitic nematodes compared to monoculture soils.

Summary: This study assessed greenhouse gas emissions and carbon footprint of maize production in Southwest China, finding them significantly higher than in other major maize-producing regions worldwide due to factors like nitrogen surplus. An integrated strategy including recommended fertilizer application rates, innovative fertilizers, and crop management could potentially reduce the carbon footprint by 41% and improve yield potential in the region. Integrated soil and crop management is crucial for sustainable maize production in tropical/subtropical regions where maize is a staple food.

Summary: This study used a carbon footprint method based on a life cycle assessment to analyze greenhouse gas emissions from pig production in China during 2000-2016. The results showed a decreasing trend in carbon footprint, with feedstuff production and manure management being the main sources of GHG emissions. The study suggests that the shift towards intensive pig production, improved feed crop cultivation, and manure management systems could significantly reduce GHG emissions in the Chinese pig sector.

Summary: Farmland abandonment in China poses a threat to grain security, and compensating the value of carbon sequestration in grain production could incentivize farmers and mitigate the issue. A study was conducted in Guangdong province to quantify the carbon sequestration value of the rice production system and assess grain security. The results showed decreased rice yield and self-sufficiency rate, as well as significant greenhouse gas emissions. The study proposed compensation standards for carbon neutrality in rice planting to ensure grain security and carbon neutrality targets in China.

Summary: This study investigated the effects of nitrogen supply on the induced defense of maize against the fall armyworm. It was found that appropriate nitrogen supply increased plant biomass and enhanced nutrient contents, leading to increased feeding by the armyworm. However, when combined with herbivore attack or jasmonic acid application, lower nitrogen supply increased susceptibility to pests while higher nitrogen supply improved defense against pests. Changes in nutrient levels and volatile organic compound emissions caused by nitrogen supply could explain these opposite induced defense responses in maize.

Summary: In this study, we conducted a 270-day in situ experiment on a long-term maize farm to explore the microbial mechanisms that trigger the priming effect (PE) in the presence of maize residues. We found that the application of chemical nitrogen decreased soil organic carbon (SOC) mineralization and the positive PE, while increasing residual carbon mineralization and microbial carbon use efficiency. This research highlights the importance of understanding microbial community structures and the functions of keystone microbial taxa in carbon turnover and the PE in farming systems.
