We discovered an error in our article, involving the use of an incorrect value for the ideal gas law constant, R , of 1.08205, instead of the correct value 0.08205. We also discovered an incorrect conversion from moles of N₂O to moles of N, 1 mole N/mole of N₂O was used instead of the correct value of 2 moles of N/mole of N₂O). The incorrect value of R and mole conversion were used in N₂O gas flux calculations. This affects a number of values presented in the article, noted below, although the changes do not have a material effect on interpretation of the results or the implications of the study.

Error on p. 956 :

In Equation 1, the correct value for R is 0.08205, not 1.08205.

Error on p. 959 :

Old incorrect text: The flux of N₂O was significantly higher from SND (63 μg N m⁻² h⁻¹) and GEO (55 μg N m⁻² h⁻¹) than from P&S (3 μg N m⁻² h⁻¹).

Corrected text (changes in bold): The flux of N₂O was significantly higher from SND (1653  μg N m⁻² h⁻¹) and GEO (1453  μg N m⁻² h⁻¹) than from P&S (86  μg N m⁻² h⁻¹).

Error on pp. 959–960 :

Old incorrect text: We calculated a mass balance for N entering and exiting the drainfields to help quantify loss pathways (Fig. 4). In P&S, outputs (514 g N m⁻² yr⁻¹) of N accounted for 87.6% of inputs (588 g N m⁻² yr⁻¹) to the drainfield, with 12.4% (74 g N m⁻² yr⁻¹) unaccounted for. Loss of N occurred mainly as dissolved N species, comprised of NO₃ (83%), organic N (16%) and NH₄ (1%). Nitrous oxide in gas and dissolved phases accounted for 0.04% of N outputs, suggesting N₂O production was not a major loss pathway in P&S.

Nitrogen was better accounted for in SND and GEO, with outputs (2194 and 2170 g N m⁻² yr⁻¹) accounting for 95.1 and 94.1% of inputs (2306 g N m⁻² yr⁻¹), respectively. Loss of N occurred mainly as dissolved N species, comprised of NO₃ (84–85%), organic N (14–15%) and NH₄ (<1%). Nitrous oxide in the gas and dissolved phase accounted for 0.08% of N loss in SND and GEO, indicating this was not an important pathway for net N loss in either drainfield type.

Corrected text (changes in bold): We calculated a mass balance for N entering and exiting the drainfields to help quantify loss pathways (Fig. 4). In P&S, outputs (515  g N m⁻² yr⁻¹) of N accounted for 87.6% of inputs (588 g N m⁻² yr⁻¹) to the drainfield, with 12.4% (73  g N m⁻² yr⁻¹) unaccounted for. Loss of N occurred mainly as dissolved N species, comprised of NO₃ (83%), organic N (16%) and NH₄ (1%). Nitrous oxide in gas and dissolved phases accounted for 0.2% of N outputs, suggesting N₂O production was not a major loss pathway in P&S.

Nitrogen was better accounted for in SND and GEO, with outputs (2208 and 2182  g N m⁻² yr⁻¹) accounting for 95.8 and 94.6 % of inputs (2306 g N m⁻² yr⁻¹), respectively. Loss of N occurred mainly as dissolved N species, comprised of NO₃ (84–85%), organic N (14–15%) and NH₄ (<1%). Nitrous oxide in the gas and dissolved phase accounted for 0.6–0.7% of N loss in SND and GEO, indicating this was not an important pathway for net N loss in either drainfield type.

我们在文章中发现了一个错误，涉及使用理想气体定律常数R的不正确值1.08205，而不是正确值0.08205。我们还发现从N ₂ O摩尔到N摩尔的不正确转化，使用1摩尔N /摩尔N ₂ O代替了正确的2摩尔N /摩尔N ₂ O值。在N ₂ O气体通量计算中使用了不正确的R和摩尔转化率值。尽管这些更改对结果的解释或研究的含义没有实质性的影响，但这影响了本文中提出的许多价值，如下所述。

p错误。956：

在公式1中，R的正确值为0.08205，而不是1.08205。

p错误。959：

旧的错误文本： SND（63μgN m ^-2 h ^-1）和GEO（55μgN m ^-2 h ^-1）的N ₂ O通量明显高于P＆S（3μgN m ^-2 h）^-1）。

纠正的文本（以粗体显示）： N中的磁通₂ O的从SND显著更高（1653 微克n×m个^-2 ħ ^-1）和GEO（1453 微克n×m个^-2 ħ ^-1）比从P＆S（86 微克Ñ m ^-2 h ^-1）。

pp。959–960出现错误：

旧的不正确的文字：我们计算了N进入和离开排水区的质量平衡，以帮助量化损失途径（图4）。在P＆S中，N的输出量（514 g N m ^-2  yr ^-1）占流失场的输入量（588 g N m ^-2  yr ^-1）的87.6％，占12.4％（74 g N m ^-2  yr ^-1）^{- 1}）无法解释。N的流失主要是溶解的N物种，包括NO ₃（83％），有机N（16％）和NH ₄（1％）。气相和溶解相中的一氧化二氮占氮产量的0.04％，表明N ₂ O的产生不是P＆S的主要损失途径。

氮在SND和GEO中的占比更好，产出（2194 g N m ^-2  yr ^-1和2194 g N m ^-2 yr ^-1）分别占输入的95.1％和94.1％（2306 g N m ^-2  yr ^-1）。N的损失主要是溶解的N物种，包括NO ₃（84-85％），有机N（14-15％）和NH ₄（<1％）。气相和溶解相中的一氧化二氮占SND和GEO中N损失的0.08％，表明这不是两种流失类型中N净损失的重要途径。
