Abstract

The aim of this study was to elucidate the interrelationship between the spatial variability of soil respiration and the spatial variability of soil redistribution as well as other soil and crop properties. The study was carried out in a small agricultural watershed subjected to water and tillage erosion processes. During three crop cycles (one of sugar beet, two of winter wheat) soil respiration, soil temperature, and soil moisture were measured in situ at least bi-weekly at 20–22 locations. Effects of differences in soil temperature and moisture, erosional and depositional status, plant and soil properties were analysed. The results highlighted that : effects of spatial differences in soil temperature and moisture on soil respiration were marginal; Differences in median grain size and bulk density had the most consistent effect on soil respiration; During most measuring phases respiration was smaller at erosional compared to depositional sites
