The organic nitrogen, particulate phosphorus, and organic carbon in water percolating from soil and river stay in the soil/river, while temperature, inorganic nitrogen and SRP follow the water to the aquifer. Inorganic nitrogen is subjected to denitrification in the aquifer (see Chapter [[start:hype_model_description:hype_np_soil#denitrification|Nitrogen and phosphorus in land routines - Denitrification]]). | The organic nitrogen, particulate phosphorus, and organic carbon in water percolating from soil and river stay in the soil/river, while temperature, inorganic nitrogen and SRP follow the water to the aquifer.
