Measurements of gas flow through soil columns of loam from Kjettslinge, Uppland, Sweden, gave average NO production rates of 0.06 +/- 0.01 ng of NO N g of soil min in aerobic conditions and 3.7 +/- 0.6 ng of NO N g of soil min in anaerobic conditions at 25 degrees C. Approximately 30% of the NO(3) loss in anaerobic conditions was as NO. In aerobic conditions an equilibrium concentration for NO was found. Above this concentration there was uptake of NO. Autoclaved samples indicated that less than 10% of the NO production was abiological, and there was no abiological NO uptake. The NO production reached anaerobic rates at soil O(2) levels between 0.5 and 0.05%.
对瑞典乌普兰郡凯捷斯林格壤土柱中气体的测量表明，在 25°C 条件下，有氧时平均每克土壤 min 产生 0.06 ± 0.01ng 的 NO 氮，无氧时产生 3.7 ± 0.6ng 的 NO 氮。在无氧条件下，大约 30%的 NO3 损失为 NO。在有氧条件下，发现了一个 NO 的平衡浓度。在这个浓度以上，NO 被吸收。经过高压灭菌的样本表明，不到 10%的 NO 产生是非生物的，并且没有非生物的 NO 吸收。当土壤中的 O2 水平在 0.5%到 0.05%之间时，NO 的产生达到了无氧的速度。
