Summary: The study investigated the impact of soil tillage and crop type on soil respiration in a typical Central European agricultural site with crop rotation. Results showed that soil respiration was significantly higher under no-tillage treatment compared to mouldboard ploughing, particularly for summer crops. Differences in soil water content could contribute to this variation. Six models were tested to simulate soil respiration, with Normalized Difference Vegetation Index improving model performance. Specific models for different crops and treatments were recommended to enhance accuracy and reduce uncertainty.

Summary: Soil organic carbon (SOC) is an important indicator of soil health. In addition to SOC, other biological indicators can also provide information about soil carbon dynamics and microbial activity. This study examined the drivers of these indicators, their relationships, and the effects of soil health practices on indicator values. The results showed that the indicators were influenced by temperature, precipitation, and clay content. There were strong correlations among the indicators, especially between SOC and permanganate oxidizable C. Soil health practices such as reduced tillage and cover crop inclusion had positive effects on indicator values. The response to these practices was more pronounced in areas with higher precipitation. Based on cost, sensitivity, interpretability, and availability, a 24-hour potential C mineralization assay was identified as the most beneficial measurement to be conducted with SOC.

Summary: This study used large-scale macrocosm experiments to explore the impact of viruses on microbial mortality and dissolved organic matter (DOM) processing in aquatic ecosystems. The results showed that viral activities can significantly transform microbial biomass into DOM and release viral lysate DOM into water columns. Viral lysis was stimulated by sinking organic carbon at the bottom of stratified ecosystems, indicating a potentially complex viral impact on DOM production and utilization.

Summary: Agriculture faces the challenge of meeting competing societal demands to produce food, fiber and fuel while minimizing negative environmental impacts. This necessitates the establishment of long-term agricultural field experiments to study the behavior of different cropping systems. A new experiment has been implemented at Rothamsted to examine the behavior of contrasting cropping systems and initial yield data has been reported.

Summary: The study found that no-tillage can lead to stratification of soil chemical parameters, while continuous mouldboard ploughing can prevent the stratification of most parameters. However, there was no significant difference between long-term infrequent tillage and no-tillage treatments, and infrequent tillage could not effectively ameliorate the stratification of soil chemical parameters.

Summary: This study highlights the importance of soil health indicators that link to ecosystem services and crop yield. The research identified CO2 flush, KMnO4-extractable C, and concentrations of certain elements as the most promising indicators related to crop yield. Soil biological properties may also be considered in routine tests for measuring soil health alongside physical and chemical properties.

Summary: This study examines the impact of projected climate change on corn and soybean yield and income returns in Nebraska. Results show that wetter winter, wetter spring, and dry summer seasons lead to yield reductions for corn, but have less impact on soybean yield. However, income returns are more stable for soybean compared to corn. Disk tillage and corn-soybean rotation with 80 kg-N/ha are recommended for the highest and stable income returns in the near-future.

Summary: This study evaluated the effects of crop rotation, conservation tillage, and low-input strategies on soil quality and farming performance. The results showed that implementing crop diversification and reducing soil disturbance and chemical inputs can improve soil quality and increase crucial variables while maintaining stable yields. Crop diversification has significant benefits in Mediterranean areas and represents a promising strategy for more sustainable land management.

Summary: This study assessed the impact of conservation tillage on soil quality, earthworm populations, and root growth in organic farming. It was found that conservation tillage improved soil physical quality and increased earthworm populations, but biological activity did not fully compensate for soil compaction after 16 years without ploughing in sandy soil.

Summary: The study found that cropping practices have different effects on soil fungal communities and guilds, with consistent impact on AMF and plant pathogenic fungi from reduced fertilization. The structure of fungal communities varies significantly between sites, crops, and climatic conditions, highlighting the need for more cross-site studies to manage beneficial soil fungi in agricultural systems.

Summary: This study assessed the impact of different types of organic farms and tillage methods on yield dynamics. The results showed that mixed farming (organic farm) performed well in terms of high yield and yield stability. However, for potatoes, cash crop cultivation and non-inversion tillage in stockless farming had higher production risks.

Summary: Rush skeletonweed is an invasive weed in winter wheat/summer fallow rotations in the low to intermediate rainfall areas of the inland Pacific Northwest. Effective control of rush skeletonweed during the summer fallow phase can be achieved through a combination of fall application of picloram and a burn-down treatment in August prior to winter wheat seeding.

Summary: This study characterized the population structure of Salsola tragus in the inland Pacific Northwest using a genotyping-by-sequencing approach. The results showed that the population in this region is mainly comprised of a single, tetraploid species with weak population structure. Despite high phenotypic variability, agronomic weed managers can consider S. tragus as a single entity for management purposes, as there is no evidence of cryptic subgroups with differential responses to management inputs.

Summary: The study aimed to determine the dose response of rush skeletonweed to picloram applied in the fall or spring with different sprayers, and evaluate the impact on injury and grain yield in subsequent winter wheat crops. Results showed that treatments applied with weed-sensing sprayers achieved similar efficacy to broadcast treatments, but at lower doses. Fall picloram applications did not reduce winter wheat grain yields. Spring broadcast applications of picloram reduced grain yields, and the reduction increased with higher picloram rates. Therefore, applying picloram in the fall with a weed-sensing sprayer effectively controls rush skeletonweed without significant impact on winter wheat grain yields.

Summary: Smooth scouringrush, a troublesome weed in no-till cropping systems, can be effectively controlled by adding an organosilicone surfactant to glyphosate herbicide. The addition of the surfactant improves the efficacy and consistency of control through stomatal flooding. Daytime applications of the herbicide are generally more effective than nighttime applications, but there may be exceptions depending on environmental conditions.
