Which code does this activity belong in?
Nitrogenous Fertilizer Manufacturing covers establishments that produce fertilizer products where nitrogen is the primary nutrient component. The key distinction from Phosphatic Fertilizer Manufacturing is the chemical basis of the product; phosphatic fertilizers center on phosphorus rather than nitrogen. Establishments that merely combine pre-made ingredients are classified in Fertilizer (Mixing Only) Manufacturing, whereas nitrogenous fertilizer manufacturers must be engaged in producing the nitrogenous materials themselves or deriving them from sewage or animal waste before mixing.
