Última Root Growth and Nitrogen Utilization of a Leek Crop and an Undersown Catch Crop Organic Eprints Nielsen, Dr. Kai Lønne; Thorup-Kristensen, Dr. Kristian. After its late harvest a leek (Allium porrum) crop will normally leave large quantities of nitrogen (N) in the soil which may be subject to leaching. A possible method to reduce N leaching losses is to establish a catch crop before the harvest of the leek crop. It was the aim of this study to investigate the effects of incorporating a catch crop in a leek crop with minimal competition and to monitor how root growth affected N availability across soil depths at different distances between catch and leek crop rows. To reduce competition between both crops leek was planted at 0.5 and 0.75 m row distances and chicory (Cichorium intybus) as a catch crop at an interrow spacing of 0.75 m. Minirhizotron glass tubes were inserted in the middle of the interrow...
