| Résumé : |
The Area of Natural Interest of Gallecs is nowadays one of the largest areas of arable land organically managed in Catalonia. In 2005 a project was launched to convert fields to organic farming and recuperate traditional crop varieties. The aim of this work is to analyse the changes in weed diversity, including both segetal and rare species, and of crops in 20 fields (ca. 46 ha) after the conversion to organic farming during 5 cropping periods (2005-2010). The number of cultivated crops increased from 1 to 17, including ancient and local varieties of cereal and legumes. Weed biodiversity at regional scale doubled in 5 years, whereas the presence of segetal and rare species increased by 75 % and 136 % respectively. Thus, organic farming contributes to the increase and the conservation of weed diversity in arable agroecosystems, including segetal species which are currently rare or have even disappeared from most of the conventional arable fields. |
