Abstract Background and aims Perennial grass seed systems may promote soil organic carbon (SOC) storage through continuous plant cover, reduced tillage, and straw residue retention, yet few studies have explored the effects of field management practices on SOC stocks. Methods We measured SOC stocks (0–30 and 30–100 cm depth), particulate and mineral-associated organic carbon (POM and MAOM), microbial community structure, and plant biomass across 24 tall fescue seed fields of varying stand ages (2–20 years) and straw management practices (straw retention vs removal) in Oregon, USA. Results While SOC stocks did not differ among treatments at either depth, stand age and straw retention altered plant and biomass, and SOC partitioning. Specifically, older stands exhibited higher total field-level C (SOC + plant biomass) due to greater root inputs, while straw retention increased the proportion of POM in the topsoil. Together, stand age and straw retention shifted community composition and increased microbial biomass. Total PLFAs were positively correlated with %POM and soil respiration, indicating that straw retention can drive rapid C turnover. When compared to nearby land uses, tall fescue seed fields had lower topsoil C stocks than natural grasslands but higher than arable crops, underscoring the C storage potential of these systems. Conclusions Our results indicate that stand age and straw management altered SOC dynamics primarily through changes in microbial biomass and labile SOC inputs. Maintaining older perennial stands with straw retention can support higher belowground inputs and foster a larger microbial community, potentially enhancing aspects of soil health beyond SOC accumulation.

The ice-ice disease (IID) impacting the commercially important eucheumatoid seaweed Kappaphycus striatus is characterized by thallus bleaching (whitening), softening, and subsequent disintegration of the affected tissue. The occurrence of IID is thought to be stress-related release of dissolve organic carbon exudates that are utilized as substrate for microbial growth. The presence of pathogenic bacteria can subsequently induce IID manifestations that can jeopardize crop health. In this study, we investigated the role of pathogenic bacteria isolated from diseased green cultivar of K. striatus in inducing IID symptoms in healthy non-axenic brown cultivar of the same species under controlled laboratory conditions. Healthy branches of K. striatus were exposed to four distinct bacterial strains: three isolated from the diseased K . striatus ( Vibrio brasiliensis strain A8, V . brasiliensis strain B2 and V . chemaguriensis strain V1) and a positive control Cytobacillus solani strain-V2. Over a period of ten days, routine administration of each bacterium was conducted during the daily renewal of the filtered seawater medium. The occurrence of symptoms, i.e., typical of IID infection, was observed in samples subjected to additional bacterium but not under the control condition with natural microbiome. Our findings suggest that the presence of pathogenic bacteria, even under non-stressful laboratory conditions, can induce IID disease syndrome with various manifestations, including the development of wounds, abrasions, thallus bleaching, and fragmentation. The samples infected with the positive control C. solani strain-V2 exhibited the most severe bleaching at 80%, followed by V. brasiliensis strain-A8 at 60%, while V. brasiliensis strain-B2 and V, chemaguriensis strain-V1 both induced 50% thallus bleaching.
