Nitrogen dioxide (NO₂) gas damage on vegetable crops commonly occurs in plastic film houses where relatively large amounts of NO₃- are applied in acid soils. In acid soils, HNO₂ can be formed from the NO₂-accumulated during denitrification, and NO₂ can be evolved from the chemical self-decomposition of HNO₂. In this study, NO₂ gas production and its detrimental effects on plants were investigated in soils of various conditions to elucidate the mechanisms involved in the gas production. A silty loam soil was amended with
NO₂ - (500 mg N kg<SUP>-1</SUP>) and glucose, and pH and moisture of the soil were adjusted respectively to 5.0 and 34.6% water holding capacity (WHC) with 0.01 M phosphate buffer. The soil was placed in a 0.5-L glass jar with strawberry leaf or NO₂ gas absorption badge in air space of the jar, and the jar was incubated at 30℃. After 4-5 days of incubation, dark burning was observed along the outside edge of strawberry leaf and NO₂ production was confirmed in the air space of jar. However, when the soil was sterilized, NO₂ emission was minimal and any visible damage was not found in strawberry leaf. In the soil where water or NO₃ - content was reduced to 17.3% WHC or 250 mg N kg<SUP>-1</SUP>, NO₂ production was greatly reduced and toxicity symptom was not found in strawberry leaf. Also in the soil where glucose was not amended, NO₂ production was significantly reduced. In soil with pH of 6.5, NO₂ was evolved to the level causing damage to strawberry leaf when the soil conditions were favorable for denitrification. However, compared to the soil of pH 5.0, the NO₂ production and its damage to plants were much less serious in pH 6.5. Therefore, the production of NO₂ damaging plants might be occurred in acid soils when the conditions are favorable for denitrification.
