Nitrification was measured in fractions of chernozemic rendzina and lessive soil differing in aggregate size. In both soils the maximum rates occurred in aggregates between 1 and 3 mm in diameter. The effects of structural and other properties (particle composition, pore-size distribution, surface area, organic C and total N content, ratio of air volume to water volume in aggregates) proved to be insignificant except for the nitrification rate in the lessive soil, which positively correlated with the fraction of particles between 20 and 50 microm in diameter.
