Summary: Cover crops are increasingly used to provide multiple ecosystem services, but the role of weeds in these cover crop plant communities is not well studied. Weeds in cover crops can enhance ecosystem service provisioning in some cases, but in other cases they should be managed to limit weed biomass and fecundity, depending on the context.

Summary: Broadacre crops require relatively higher nutrient input to achieve yield targets, making efficient nutrient use in arable farmlands crucial. Enhancing soil quality through integrated nutrient management approaches, such as the use of organic amendments alongside fertilizers, can improve soil nutrient dynamics and reduce excessive fertilizer use. Studies have shown that the combination of compost and fertilizers can improve soil health, fertility, and crop yield, making it a potentially viable alternative to sole reliance on chemical fertilizers in farmlands.

Summary: This study investigates the effects of fertilization management on soil microbial communities and their functional profiles, and how it impacts nutrient use efficiency (NUE) and crop productivity. The results show that the composition of rhizosphere bacterial community and their nutrient cycling-related functions are significantly influenced by fertilization management. Moderate compensation of nutrient cycling functions leads to the highest NUE and crop productivity in combined organic-mineral fertilization treatment, while insufficient or standard mineral fertilizer input decreases NUE and crop productivity.

Summary: Crops that provide ecosystem services beyond crop production are gaining attention and interest. Cover crops, grown either as the sole crop or in mixtures, contribute to achieving the United Nations' sustainable development goals by providing multiple ecosystem services. However, it is not known to what extent the ecosystem services provided by cover crops are affected by interactions between genotype, environment, and management. Understanding these interactions can help maximize the ecosystem services of cover crops while minimizing their impact on ecosystems. Therefore, a paradigm shift in defining, managing, and utilizing cover crops is proposed.

Summary: The three-year field experiment in Scotland found that over winter cover crops can significantly increase grain yield and nitrogen concentration of subsequent spring barley crops, but this comes with increased costs and decreased profitability. While cover crops had mostly neutral effects on soil properties, they did loosen the surface soil. Overall, cover crops showed potential benefits for cereal production without negative impacts on soil health or agronomic sustainability.

Summary: Compared to virgin land, croplands have lower organic carbon storage due to soil tillage and decreased plant inputs. Cover crops grown in-between crops appear to be the most effective method for increasing cropland organic carbon stocks. However, existing studies have limitations and more research is needed for better design and understanding.

Summary: Recent advances in biotechnology make it possible to obtain glyphosate-resistant corn genotypes, allowing for large-scale usage of this herbicide. However, the use of glyphosate can exacerbate water deficit effects during the initial development of crops. This study aimed to investigate the physiological and biochemical effects of glyphosate on glyphosate-resistant (RR) corn plants under water deficit conditions. Our results show that glyphosate application does not negatively impact RR corn plants under moderate water deficit but negatively affects root length and volume in the absence of water deficit.

Summary: Peanut pod yield and its response to fertilizer-K are influenced by the interaction between the environment and plant density. Planting density and K fertilization have a greater impact on rainfed areas than irrigated environments. Increasing plant density leads to an increase in peanut leaf area index and dry matter accumulation, but a decrease in stomatal conductance, particularly in rainfed fields. The application of 50 kg ha(-1) of K in low-K soil can increase leaf K concentration, stomatal conductance, and yield in rainfed fields, while in irrigated fields, yield increases up to a certain plant density and does not further increase with higher densities or K application.

Summary: Soil aggregation is a critical indicator for assessing soil health and its role in protecting against erosion, storing organic carbon, and supporting soil organisms. The choice of initial sieve opening size impacts the determination of dry-stable and water-stable mean-weight diameter (MWD) in fine-textured soils. While initial sieving through 8 mm resulted in higher dry-stable MWD, the soil stability index was not affected by the sieve size. Both methods provided consistent interpretations of soil management practices and demonstrated the depth effect on water-stable MWD. The study suggests that using a 4.75-mm sieve opening for soil analysis can provide reasonable estimates and interpretations of surface soil aggregation.

Summary: Soil management systems have a direct impact on the relationship between soil and plants, but there is limited research on the influence of long-term management systems on the physiological quality of soybean seeds. The effects of pre-harvest desiccation on seed quality, particularly seed longevity, are also not well understood. This study aimed to evaluate the physiological quality of soybean seeds grown under conventional tillage and no-tillage systems, with and without the use of desiccants. Overall, seeds cultivated under conventional tillage showed higher vigor, while the no-tillage system had superior seed longevity. However, the application of desiccants reduced seed longevity in both systems.
