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: 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: The objective of this study was to develop a model for simulating the leaf color dynamics of winter wheat under different nitrogen rates. RGB data of winter wheat leaves were collected and a color model was developed using the collected data. The results showed that leaf color changes went through three stages, and different linear functions were used to simulate the dynamics of RGB values. The developed model was validated and used to render wheat leaves in 3D, which showed good agreement with the observed leaf color dynamics.

Summary: This study characterized the CO2 fluxes of a winter wheat-summer maize rotation cropland in different growing periods and identified the driving factors using long-term monitoring data. Leaf area index (LAI), photosynthetically active radiation (PAR), and soil water content (SWC) were found to be important drivers of CO2 fluxes in both wheat and maize seasons. The findings provide valuable insights into the carbon cycle of cropland ecosystems under climate change.

Summary: This study quantifies the impact of waterfowl grazing on winter wheat yield, crop height, and nutrient content using two parallel methods: exclosure experiments and yield assessments. The study found that waterfowl grazing significantly reduced crop height during winter and early spring, but compensatory growth restored it to normal levels at harvest time. The effect on grain yield varied from non-significant to a 6% loss, with significant losses only occurring when grazing continued into spring. Large-scale scaring efforts had limited effects on grain yield loss when fields were grazed during spring but prevented damage in winter-grazed fields. These findings suggest that economic impacts from grazing waterfowl on winter wheat are rare in the study area and possibly in other temperate regions.

Summary: Establishment of improved perennial pasture systems can enhance soil health in semiarid regions like the Texas Southern High Plains. Utilizing composted animal manure as a soil amendment can increase soil organic carbon and improve microbial communities. Even a one-time application of compost at a relatively low rate can boost soil organic carbon in semiarid pastures, with greater effects observed in fertilized grass-only pastures compared to those with legume establishment.

Summary: This study investigated soil microbial biomass and composition in turfgrass systems in semiarid climates, finding that microbial biomass in residential soils was influenced by home age. Soil organic matter and silt content were identified as key factors affecting microbial community. The shift from fungal to bacterial dominated microbial communities in urban environments as landscapes matured was attributed to long-term effects of irrigation, fertilization, and pesticide use. Time after establishment was deemed more important than subtle differences in management in development of soil microbial communities, suggesting achievable soil health and resource conservation goals with relatively low levels of management over time in this setting.

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.
