- •
Bulk inorganic nitrogen depositions range between 2.81 and 4.56 kg N ha− 1 yr− 1 in heathlands of North-Western Spain.
- •
The highest bulk NO3− and NH4+ deposition rates were displayed in the rainiest months.
- •
Annual bulk NO3− deposition was comparable to bulk NH4+ deposition in La Majúa and was higher in San Isidro.
- •
NH4+/NO3− ratio was characteristic of industrialized areas in San Isidro and of undefined areas in La Majúa.
- •
N-sensitive heathlands of North-Western Spain are susceptible to elevated N deposition rates.
