All three crops are late-harvested crops with a long growing season, but they have been found to have very different root growth. At their optimal N supply, carrot left 27 kg nitrate-N\/ha in the top 100 cm of the soil, leek left 87 kg N\/ha and white cabbage left only 11 kg N\/ha, in accordance with previously published differences in rooting depth among the three crops. Compared at a supply of 160 kg N\/ha, 52, 65 and 4 kg nitrate-N\/ha was left in the soil by carrot, leek and white cabbage respectively. Apart from an extensive root system, while cabbage also had a much higher N-uptake capacity than the two other crops. The significance of differences in root growth, N-uptake capacity and other factors in determining the ability of the three crops to deplete the soil inorganic N pool is discussed.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-57793","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"THORUP-KRISTENSEN K,DANISH INST AGR SCI,DEPT FRUIT VEGETABLE & FOOD SCI;POB 102;DK-5792 AARSLEV, DENMARK.","annee":"1999","mois":"10","numero":"49:2","page":"92-97","auteurs":[{"ID":56228,"post_author":"0","post_date":"2018-12-04 07:13:54","post_date_gmt":"2018-12-04 06:13:54","post_content":"","post_title":"Sorensen","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"sorensen-5","to_ping":"","pinged":"","post_modified":"2018-12-04 07:13:54","post_modified_gmt":"2018-12-04 06:13:54","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/sorensen-5\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":57792,"post_author":"0","post_date":"2018-12-04 07:44:41","post_date_gmt":"2018-12-04 06:44:41","post_content":"","post_title":"Thorup-kristensen","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"thorup-kristensen","to_ping":"","pinged":"","post_modified":"2018-12-04 07:44:41","post_modified_gmt":"2018-12-04 06:44:41","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/thorup-kristensen\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":54039,"post_author":"0","post_date":"2018-12-04 06:29:44","post_date_gmt":"2018-12-04 05:29:44","post_content":"","post_title":"ACTA AGRICULTURAE SCANDINAVICA SECTION B-SOIL AND PLANT SCIENCE","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"acta-agriculturae-scandinavica-section-b-soil-and-plant-science","to_ping":"","pinged":"","post_modified":"2018-12-04 06:29:44","post_modified_gmt":"2018-12-04 05:29:44","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/acta-agriculturae-scandinavica-section-b-soil-and-plant-science\/","menu_order":0,"post_type":"source","post_mime_type":"","comment_count":"0","filter":"raw"}]},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v23.6 (Yoast SEO v23.6) -
