At room temperature, air dry calcareous soils sorbed from 0.5 to 2% NO by weight within 10 to 15 min from a dry air stream containing 1.6% NO by volume. The sorption capacity increased with 0.4 to 0.7‐th power of NO concentration and the soil specific surface and was independent of the soil acidtitratable basicity. The sorption rate was approximately proportional to the unused portions of the capacity with rate constants ranging from 0.4 to 1 min ‐1 . Less than 10% of sorbed NO was lost by heating at 105C or a suction of 65 cm Hg for 24 hours. The NO sorbed by the soil was converted to NO ‐ 3 .
