Biogas slurry has the problems of having a low concentration, having a large production
volume, and containing many small-molecule organic pollutants. During the fertigation …

Human-induced inputs of nitrogen (N) and phosphorus (P) into the biosphere have reached
unprecedented levels, particularly N, leading to an escalating global anthropogenic N: P …

Coastal lagoons can act as sinks and sources of a wide range of substances, including
nutrients, and pollutants. In these ecosystems, primary production is limited more by nitrogen …

Nitrate contamination of groundwater due to improper management of fertilizer application
and controls during agricultural activities is an escalating worldwide issue. Numerous …

Livestock slurry has been reported to be a potential secondary raw material as it contains
macronutrients‑nitrogen, phosphorus and potassium-, which could be valorised as high …

Nitrite reduction has often been treated as a biotic process in water treatment systems, but it
also occurs abiotically, and it is difficult to distinguish both reactions as they can co-occur at …

High levels of ammonium (NH 4+) in groundwater can threaten the health of surface
