A field receives nitrogen inputs as follows: 120 kg N ha\(^{-1}\) from fertilizer, 30 kg N ha\(^{-1}\) from biological fixation and 5 kg N ha\(^{-1}\) from atmospheric deposition. Losses occur by volatilisation amounting to 10 % of the total input and by leaching amounting to 15 % of the total input.
