Abstract

The soil surface of a prepared soil box (0.5 m2) was observed after two successive periods of drying, between which the macroporosity of the soil surface was destroyed by raindrop impact and washing in of sediment by surface runoff. More numerous burrows were observed after the second drying (256 compared to 183 at the first time) and they were longer and larger. The number of burrows in the vicinity of cracks was higher in both observations than if they had been distributed at random. It was concluded that the spatial relationship between burrows and cracks was dependent only on the distance between burrow and cracks, with the exception of places where cracks and burrows occupied the same location.
