The effect of size of structural aggregates on the intensity of nitrification and nitrogenase (nitrogen: acetylene oxidoreductase) activity was investigated in three soils. In two of them the nitrogenase activity was limited by addition of glucose. Aggregates of a larger diameter (2-4 mm) exhibited a considerably higher nitrogenase activity than those with a diameter smaller than 2 mm. This effect was even more pronounced when the soil samples were repeatedly intensively aerated. On the contrary, smaller aggregates (0.5-2 mm) exhibited more intensive nitrification.
在三种土壤中研究了结构团聚体大小对硝化作用强度和固氮酶（氮：乙炔氧化还原酶）活性的影响。其中两种土壤通过添加葡萄糖使固氮酶活性受到限制。直径较大（2 - 4毫米）的团聚体表现出比直径小于2毫米的团聚体明显更高的固氮酶活性。当土壤样品反复进行强烈曝气时，这种效应更加明显。相反，较小的团聚体（0.5 - 2毫米）表现出更强的硝化作用。
