The number of roots per 5 cm depth level down to 1 m was counted frequently during the growing season using mini-rhizotrons, i.e., transparent tubes inserted into the soil. Root biomass at different depths down to 1 m was estimated from soil cores taken one month before harvest. The results from the two methods were compared and root counts in the different treatments were compared with the above-ground growth and production. Nitrogen-fertilized barley in pure stand had the highest biomass both above and below ground. According to the mini-rhizotron observations this treatment also had a deeper and denser root system, until barley harvest, than the other treatments. After barley harvest, roots from the undersown lucerne continued to increase, whereas the number of roots in the undersown meadow fescue remained the same. The root system in barley/meadow fescue did not penetrate into the subsoil, where more than 60% of the number or roots in barley undersown with lucerne were found. In general, the mini-rhizotron results indicated a higher relative abundance or roots in the deeper layers than the root biomass estimated with the soil coring method."
