Summary: Soil nutrient deficiency is a major constraint to sustainable agriculture development on the Loess Plateau. Optimized agricultural management practices, such as improved fertilization, conservation tillage, and crop rotation, can enhance crop yield, economic profit, and soil fertility. A long-term study demonstrated that optimized agricultural management strategies significantly increased grain yield, economic profit, and improved soil conditions.

Summary: Crop diversification in rotations is crucial for sustainable crop production. This research analyzed the impact of soil tillage and crop rotation on the yield, energy yield, and economic profitability of different field crops. The study found that crop rotations with a diverse range of crops, particularly with a reduced share of winter wheat, significantly increased wheat grain yields and overall economic profitability. Furthermore, wheat and oilseed rape were identified as the most valuable crops in terms of energy yield.

Summary: This study aimed to evaluate the impact of conservation tillage on soil properties and yields in eastern Canada. The results showed that after long-term implementation, conservation tillage significantly increased organic matter and phosphorus and potassium content in the 0-5cm surface layer, but did not translate into higher yields. In contrast, moldboard plow performed better in terms of economic benefits under recommended nitrogen levels.

Summary: In order to better manage soil-borne oomycetes, a long-term field experiment was conducted to investigate the effects of tillage and crop rotation on oomycete communities. It was found that no tillage and crop rotation both influenced the diversity and structure of the fungal community, and the interaction effects of tillage and rotation made it more complex to manage these pathogens.

Summary: The Corn Belt of Northeast China (CBNC) is facing a decline in productivity due to long-term intensive cultivation, which threatens the sustainable development of corn and soybean. Field experiments were conducted to evaluate crop yields, economic returns, and water productivity in the CBNC from 2017 to 2020. The results suggest that continuous corn cultivation had the highest yield and income, but considering production, financial gains, and water productivity, continuous corn was still the best planting pattern for the CBNC.

Summary: Crop rotations can increase crop yield and quality, while biochar-based fertilizer application can also improve crop quality. The findings of this study provide important information for designing sustainable crop rotation systems.

Summary: Weather and topography are important drivers of spatial variability in crop yield. The relationship between crop yield and these factors shifts with precipitation, with maize generally yielding higher in low-elevation and low-slope landscape positions, and soybean in low-slope positions. Additionally, the impact of precipitation on yield-topography relationships differs between maize and soybean.

Summary: Recent advances in UAV remote sensing and image analysis have led to the development of a GIS-based framework, GAUSS, which successfully integrates large imagery datasets with manually collected data. A field cultivation experiment focusing on soybean-wheat crop rotation demonstrated the framework's effectiveness in predicting crop yield and identifying the impact of soybean cultivars on wheat yield.

Summary: The study suggests that incorporating wheat into corn-soybean rotations can increase yields and net returns, with the benefits becoming more significant over time. This diversification strategy may provide a balance between higher net returns from corn and soybean while minimizing the direct net revenue reductions associated with wheat.

Summary: Conservation agriculture is a farming system that promotes minimum soil disturbance, maintenance of a permanent soil cover, and diversification of plant species, which has been introduced in the Veneto region of north east Italy. The study found that this system did not have detrimental effects on root development and positively affected maize, soybean, and winter wheat, possibly due to increased nutrient availability. Further research on soil-specific mechanisms between soil compaction and root apparatus is warranted.

Summary: This study evaluates the long-term effects of no-tillage (NT) on crop yield and greenhouse gas (GHG) emissions in corn and soybean cropping systems in Kentucky, USA. The results show that NT can reduce soil CO2 and N2O emissions, and the effects are influenced by air temperature and soil clay content.

Summary: The impact of fall-winter crop species on subsequent soybean performance under a no-tillage system in tropical environments was evaluated. Preceding cultivation of crambe or sunflower favored nutrient uptake by soybean, and sorghum, safflower, and crambe as fall-winter crops increased soybean yield compared to fallow plots. Maize and sunflower had the highest increases in soybean yield in the second and third growing seasons, respectively.

Summary: This study aimed to compare the effects of different fertilization practices on the resilience of maize, wheat, and soybean cropping systems. The results showed that fertilization increased crop yields in unfavorable environments, but did not change crop adaptation to the environment. Maize had the highest response to nitrogen, while wheat and double-cropped soybean exhibited the highest responses to phosphorus and sulfur, respectively. These findings provide useful guidelines for fertilization management practices to increase crop resilience.

Summary: In Sweden, crop species diversity is strongly influenced by latitude and associated mean annual temperature. Mean annual precipitation and soil texture have no significant relationship with crop diversity. There is no significant change in crop diversity at the national level, but temporal trends vary between counties. Some counties show an increase in crop diversity over time, while others show no change or a decrease. Socioeconomic factors likely play a role in these temporal changes.

Summary: This study investigates the impact of ridge tillage (RT) and strip tillage (ST) on crop yields in Europe in comparison with no-till (NT) and conventional tillage (CT). The results show that, on average, NT leads to a 5.1% reduction in crop yields, while RT and ST each result in a 5% increase in crop yield over CT.
