Excess nutrients in the coastal environment have been linked to a host of environmental problems, and nitrogen reduction efforts have been a top priority of resource managers for decades. The use of shellfish for coastal nitrogen remediation has been proposed, but formal incorporation into nitrogen management programs is lagging. Including shellfish aquaculture in existing nitrogen management programs makes sense from environmental, economic, and social perspectives, but challenges must be overcome for large-scale implementation to be possible.

Litter decomposition is essential for nutrient and chemical cycling in terrestrial ecosystems. Previous research on litter decomposition has often underestimated its impact on soil nutrient dynamics and allelopathy. To address this gap, we conducted a comprehensive study involving both field and greenhouse experiments to examine the decomposition and allelopathic effects of the invasive L.

Uncovering the response of plant functional types (PFTs) to nutrient limitation caused by atmospheric deposition is critical for assessing the health of terrestrial ecosystems under climate change conditions. However, it remains unclear how atmospheric deposition and underlying ecological factors affect PFTs globally. To address this, we compiled a global dataset of four PFTs, i.

A two-year study has been conducted to optimize saffron cormlet production in a soilless cultivation system. Variations in the concentration of phosphate, boron, and irrigation events were assessed in the first year. Subsequently, after optimizing the substrate composition, the effects of nutrient solution volume and the concentration of nitrate, iron, and boron were investigated on the yield and weight of cormlets and leaves, photosynthetic activities, and productivity of nutrient solutions in the second year.

Landfill biomining is indeed a promising eco-friendly approach to sustainably manage and reclaim old dumpsites. Soil like fractions of < 8-10 mm size, also known as bioearth or good earth constitute a substantial part of the legacy waste. Detailed characterization is necessary to meet regulatory standards for the safe use of bioearth and minimize its environmental and human health impacts upon reuse.

Advances in manufacturing and trade have reshaped global nitrogen deposition patterns, yet their dynamics and drivers remain unclear. Here, we compile a comprehensive global nitrogen deposition database spanning 1977-2021, aggregating 52,671 site-years of data from observation networks and published articles. This database show that global nitrogen deposition to land is 92.
