Summary: This study conducted a field experiment to test different methods and species of cover crops. The results showed that early establishment of cover crops, specifically direct sowing or sowing 10 days before harvest, had a positive impact on biomass formation and weed suppression. The performance of cover crops varied depending on the species, sowing date, and weather conditions, but a diverse cover crop mixture showed more stable performance under variable weather conditions.

Summary: This study investigated the potential of white clover and ryegrass as cover crops to inhibit weed growth and the impact of their residue on subsequent crops. The results showed that ryegrass effectively suppressed weed growth but reduced corn yield, while white clover enhanced corn yield with less noticeable weed suppression. Based on this, it is recommended to use ryegrass as a pre-crop to reduce herbicide use in corn cultivation.

Summary: Cover crop (CC) mixtures are a promising agroecological tool for weed management. However, their suppressive effect on weeds under contrasting levels of soil resource availability is not well-documented. A two-year field experiment revealed that the outcomes of competition between CC mixtures and weed species were driven by complex interactions between resource availability and species traits.

Summary: Integrating oats as a cover crop in forage crops and their intercrops can effectively suppress weeds and enhance the quality and productivity of crops. The intercropping system with pea, Sudan grass, and barley showed the best performance. This finding is significant for weed control, improving forage quality, and increasing crop yields.

Summary: This study aimed to investigate the effects of cover crop treatments on weed control and soil qualities. The results showed that white clover, common vetch, rattail fescue, and the white clover + perennial ryegrass mixture exhibited good weed control. The soil qualities in cover crop soil generally showed increasing trends, especially in soil physical properties and microbial diversity.

Summary: This study evaluated four spring-planted cover crops for biomass production and weed suppression. The results showed that brown mustard and small grains produced similar biomass amounts, with brown mustard showing more consistent biomass production and better weed suppression.

Summary: Weeds have a negative impact on the growth and profitability of organic vegetable crops. Weed management is a major challenge for organic vegetable growers due to limited control options. Anaerobic soil disinfestation (ASD) is a non-chemical pest management technique that creates oxygen-free conditions in the soil for a specific period. This study investigated the effectiveness of warm season cover crops as carbon sources for ASD and their role in weed management. The results showed that incorporating cover crops in non-aerated conditions provided better weed control and improved tomato plant growth and yield compared to other treatments. Warm season cover crops have the potential to be used as carbon sources for ASD in organic tomato production.

Summary: Adoption of cover crops in arid agroecosystems has been slow due to concerns about water resources and soil moisture depletion. However, a study found that fall-sown small grains and certain barley varieties have the ability to suppress winter weeds in irrigated, organic systems. This suggests that these non-thirsty cover crops can be a viable option for weed control in the southwestern United States.

Summary: The study found that in southern New Mexico, through proper irrigation management and planting of winter cover crops, weed density and biomass can be effectively reduced, leading to increased maize yield. Although winter cover crops did not suppress weeds throughout the maize growing season, their effect on weed control was still significant.

Summary: Cover crops (CCs) have the potential to suppress annual weeds within agronomic cropping systems in the United States. However, this potential may vary depending on the specific environmental and management factors of different geographic areas. A meta-analysis of studies conducted in the U.S. Southeast found that CCs had a negative effect on weed density but no effect on weed biomass or cash crop yield. The key factor associated with weed density reduction was the biomass of the cover crops.

Summary: Increasing diversity in cover crops can improve ecosystem service outcomes, especially mixtures of grasses and legumes. In areas with lower soil nutrients, diversity tends to have a stronger effect, supporting the stress-gradient hypothesis.

Summary: This study estimated the winter soil cover rate before spring-sown crops in mainland France and found strong heterogeneities in soil cover between different departments. Crops associated with livestock production tended to have higher winter soil cover rates.

Summary: Modern vegetable production often uses monoculture fields, intensive tillage, and synthetic agrochemicals to manage weeds. However, there is a growing interest in sustainable practices with lower inputs. This study investigated the use of conservation tillage with interplanted living mulch or cover crop residue as an alternative weed management strategy for sweet corn. The results showed that the cover crop systems effectively suppressed weeds throughout the cropping cycle, and there was no significant improvement with the application of herbicides. However, reduced yields were observed in the cover crop treatments compared to conventional tillage in the third year.

Summary: Non-marketable crops are used to promote agroecosystem services and sustainable agriculture, but the traits and associated soil microbial communities of different crops play a role in their effectiveness. Maximum canopy height and leaf area are positively correlated with all agroecosystem services, while rooting density is associated with bacterial diversity. Some crops excel in certain services but may have trade-offs with others, emphasizing the importance of considering plant functional traits when selecting crops for agroecosystem services.
