Summary: This multi-site study conducted in the Canadian prairies found that the effects of glyphosate on soil microbial properties were not significant, with soil pH and organic carbon content having a greater impact on the composition and enzyme activities of the soil microbiome. Continued evaluation of glyphosate's effects on the soil microbiome and its functioning is important due to its widespread use as a herbicide.

Summary: Farmers in Mediterranean climate regions are increasingly growing canola in wheat-based systems to break soil-borne pathogen disease cycles, control weeds, and enhance crop marketing opportunities. A rainfed cropping systems experiment was conducted to compare the performance of canola, winter triticale, and winter wheat and measure their effects on soil water dynamics and subsequent performance of spring wheat. The results showed a decline in wheat grain yield after canola, primarily due to reduced overwinter soil water storage.

Summary: Conservation agriculture with crop rotations and residue management provides various benefits to soil and the environment. This study evaluated the impact of two medium-term rotations (canola-wheat and bean-wheat) and four residue incorporation rates on wheat grain yield and nutrient concentrations in a volcanic soil in south-central Chile. The results showed that the preceding crop and residue incorporation rates had no significant effect on wheat grain yield and most nutrient concentrations, except for potassium and magnesium concentrations.

Summary: This study investigates the impact of climate factors on wheat and maize yields in the North China Plain (NCP) and finds that irrigation practices and crop rotations substantially impact grain yield. The study also reveals that rational rotation and irrigation can reduce grain yield sensitivity to climate change and enhance food production resilience.

Summary: Despite the large domestic market for guar gum and the opportunity to diversify regional cropping systems with guar, it is often restricted to a catch crop or substitute crop following cotton failures in the U.S. Southern Great Plains. A systems research study was conducted to evaluate the integration of guar into no-till dryland winter wheat systems, and the results showed that crop rotation sequence influenced seasonal guar yields.

Summary: Row croppers in the Southeast United States are interested in diversifying their cropping systems and increasing revenue by growing a winter cash crop between summer crops, especially cotton and peanut. Double-cropping carinata between summer crops has potential to boost grower revenue and increase land use efficiency in the region. Research was conducted to quantify the effects of summer cropping history on the performance of carinata as part of diversified crop rotations in the SE US.

Summary: Long-term field trials are ideal for studying soil microbial communities, as they evolve over time in a specific cropping system. This study found that crop rotation influenced microbial biomass carbon, with continuous wheat showing higher levels compared to other rotations. Fertilizer application increased soil microbial biomass carbon by 21%, while soil moisture deficit had no effect on the soil microbiome.

Summary: This study developed a satellite-based data fusion approach to map crop rotation at field-scale and analyze the effects of environmental factors on crop yields in southern Brazil. The results showed that continuous soybean planting and one-year soybean with one-year corn rotation were the most common crop rotation patterns in the region. The study also found that crop rotation had significant effects on soybean yields, with variations depending on the regions and years of rotation. Furthermore, climate conditions and soil organic carbon were identified as important factors influencing crop rotation. This study provides the first crop rotation map for the state of Rio Grande do Sul and serves as a foundation for similar databases in other states and countries.

Summary: This study evaluated the environmental profile of potato and wheat in a crop rotation system in the region of Galicia, Spain, finding that the local Galician wheat had the lowest environmental impact in terms of land management, financial function, and energetic value. However, in terms of productivity, potato was identified as the best crop. Comparatively higher yield made potato a more productive crop, even though the environmental impacts of wheat were lower in a rotation system compared to monoculture. This study highlights the importance of using Life Cycle Assessment for understanding the environmental impacts of agricultural systems and provides a basis for future comparison of rotational agricultural systems in the region.

Summary: This study evaluates the effect of lupin cultivation in Galician winter wheat-based rotation systems from an environmental and economic perspective. The results show that incorporating lupin in the rotation systems leads to significant reductions in environmental impacts, such as global warming and marine eutrophication. Additionally, favorable economic consequences were observed in certain rotation systems. This research highlights the importance of understanding the environmental impacts of diversification strategies in agricultural systems and serves as a baseline for a comprehensive sustainability assessment.

Summary: The objective of this study was to test the ability of different wheat genotypes to take up nitrogen from preceding legume crops under different water scenarios. The results showed that drought-tolerant genotypes had higher nitrogen nutrition index, biomass, yield, and nitrogen output under low water and nitrogen inputs, while other genotypes performed better under non-limiting conditions. Therefore, this study confirms differences between wheat genotypes in nitrogen uptake from preceding legumes in crop rotations under different water levels and highlights the potential of nitrogen nutrition index to assess wheat nitrogen status.

Summary: Crop rotation and soil tillage significantly influence the diversity, co-occurrence network and assembly processes of rhizobacterial communities. The interaction between crop rotation and tillage has a stronger effect on community composition than their individual contributions. The rhizobacterial network is more connected under crop rotation and the connectivity decreases with decreasing tillage intensity. Soil tillage determines the dominant assembly process in rhizobacterial communities.

Summary: Long-term heavy application of inorganic fertilizers reduces soil quality and biodiversity. Organic amendments have been found to have a positive impact on soil quality. This study demonstrates that the combined application of organic and inorganic fertilizers improves crop yield, soil chemical properties, microbial activity, and enzyme kinetic parameters, as well as enhances microbial growth and catabolic diversity.

Summary: Drought is a pressing issue worldwide, and selecting wheat genotypes adapted to changing climatic conditions is crucial. This study evaluated 156 bread wheat genotypes, including landraces and modern varieties, under different drought treatments. The results showed that landraces had higher yield stability and protein content under drought stress, suggesting their potential for developing drought-tolerant modern wheat varieties. Effective utilization of landraces in breeding programs is important for developing climate-resilient wheat varieties.

Summary: This study evaluated the changes in nutrient uptake, nutrient use efficiency, and yield of 20 cotton cultivars released in the USA between 1953 and 2018. The results showed that modern cotton cultivars have increased total nutrient uptake but slower improvement in nutrient use efficiency. The findings highlight the potential for enhanced nutrient uptake traits in cotton.
