Plant biologicals are a widely used yet loosely defined term that generally refers to products intended to enhance plant growth, productivity, and protection against pests and diseases. Many, such as microbial inoculants, biostimulants, and plant-derived compounds, also influence microbial communities and processes. The functionality has been recognised for decades, but consistent field-level benefits remain difficult to demon...

Aquaculture farming discharges large volumes of fish sludge, consisting of particulate organic matter from feed spill and feces. Fish sludge from land‐based salmonid aquaculture systems can potentially be used to feed low‐trophic species such as marine polychaetes and insects. Further use of these invertebrates as feed may provide a more sustainable feed chain. However, food security must not compromise feed or food safety. Th...

Cover crops increase carbon (C) inputs to agricultural soils, and thus have the potential to mitigate climate change through enhanced soil organic carbon (SOC) storage. However, few studies have explored the fate of belowground C inputs associated with varying root traits into the distinct SOC pools of mineral‐associated organic carbon (MAOC) particulate organic carbon (POC). Therefore, a packed 0.5 m column trial was establis...
