Summary: Soil fertility in organic agriculture is dependent on microbial cycling of nutrients from legume cover crops and animal manure, but the labile carbon and nitrogen in these inputs can lead to increased nitrous oxide emissions. Our research shows that managing the rate and timing of organic input additions, as well as preventing the co-location of legume cover crops and manure, could help mitigate N2O emissions.

Summary: Efficient recycling of manure nutrients through local cropping systems is crucial for reducing the environmental impact of the dairy industry. However, manure alone cannot meet crop nitrogen needs, necessitating the use of synthetic fertilizer. Transportation of manure at least 12.9 km and replacing synthetic fertilizer phosphorus on 96% of cropland is necessary to balance phosphorus with crop production.

Summary: The study compares different strategies to reduce gaseous emissions from slurry application in conservation agriculture. It found that pretreatment by acidification, placement under the stubble, and irrigation significantly reduced nitrogen losses, while delayed fertilization reduced N2O emissions. These strategies are the most suitable for slurry application in conservation agriculture.

Summary: The potential of digital agriculture relies on mathematical models to encode 'cause-and-effect' relationships and support on-farm decision making. Irrigation decision making, particularly for woody perennial crops like grapevines, is influenced by the relationship between applied water and crop yield. Process-based models are used to represent these complex relationships in an interpretable and generalizable manner.

Summary: The study reveals that mulched groundcovers can significantly increase soil organic matter and nitrogen availability in the short term compared to conventional tillage. Spontaneous vegetation has a positive impact on soil structure, soil penetration resistance, and soil biological health. These results suggest that mulched groundcovers can improve soil health and potentially enhance the sustainability of the wine sector.

Summary: This article introduces a method that uses machine learning to emulate process-based agricultural system models and discusses its application in agricultural management and policy-making. By simulating crop production and soil carbon dynamics in a typical cropping region, the researchers found that ML-based emulators can accurately and quickly reproduce the predictions of the original model, capturing main processes with less input data. This approach can guide agricultural management strategies and address global environmental challenges arising from agricultural intensification.

Summary: The threat of environmental degradation has brought great attention to clean energy production and transportation, yet the limited scope of energy consumption in Sichuan province has resulted in the abandonment of large-scale clean energy sources. On the other hand, the development of modern greenhouse cultivation has introduced a new type of electrical load in the grid, transforming the agriculture industry. The results show that power consumption is mainly driven by an artificial lighting compensation system.

Summary: The study shows that the modern integrated crop-livestock system (ICLS) in China performs better in terms of environmental pressure, energy sustainability, and economic benefits, but has lower productivity compared to traditional specialised cropping systems (SCS). When substituting chemical nitrogen with manure fertiliser nitrogen, both ICLS and SCS show decreased productivity and environmental pressure, with ICLS displaying a less pronounced trade-off.

Summary: Water shortage and poor soil fertility are the main barriers to the sustainable development of peanut production in the semi-arid areas of Northeast China. Understanding the dynamics of soil water-nitrogen and crop water/nitrogen use is crucial for developing effective water and nutrient strategies. This study used an agro-hydrological model to simulate soil water and nitrogen status, as well as peanut growth, and found that the optimal irrigation amount for peanut cultivation in this region is 80-97 mm.

Summary: Simulations of crop yield under climate change show significant variations depending on models, locations, species, management strategies, and Representative Concentration Pathways. A meta-model based on site-level simulations was developed to understand the effects of climate and adaptation on yield change for maize, rice, wheat, and soybean. The study found that adaptation plays a crucial role in mitigating projected yield losses under the RCP4.5 scenario, with most influential factors being adaptation strategy and climate change. These results highlight the importance of implementing adequate adaptation strategies to mitigate the impact of climate change on crop yields.

Summary: In this work, the regularity of rainfall temporal series in the state of Pernambuco, northeastern Brazil, from 1953 to 2012 was analyzed using the sample entropy method (SampEn). The study found that the regularity of rainfall decreases from the inland Sertao region towards the coastal Zona da Mata region. The analysis of different time periods and comparison of regions showed variations in rainfall amount and regularity, which were associated with specific climatic phenomena such as El Nino and La Nina episodes. This study contributes to the application of information theory-based methods in climatological studies.

Summary: This study presents a methodology for analyzing the distribution and spatial-time dependence of the supply of forest bioelectricity in Brazil. The results indicate that the central-southern states of Brazil are the main locations for forest thermals. The decrease in spatial autocorrelation between 2000 and 2019 suggests the impact of new thermoelectric plants established by large groups throughout the country. The study also identifies high-powered clusters and outliers, indicating the possibility of associating thermoelectric plants with other activities.

Summary: The accurate estimation of biomass in tropical dry forests is still a challenge. In this study, a methodology was developed using field and orbital data, regression models, and high-performance computation to estimate biomass stocks in a tropical dry forest in Northeast Brazil. By combining various vegetation spectral indices and satellite sensor data, regression model equations were generated to predict biomass stocks. These equations, along with other map data, were used to plot a map of biomass stock in the entire region.
