Rice Paddy Soil Seedbanks Composition in a Mediterranean Wetland and the Influence of Winter Flooding

Soil seedbanks are defined in composition and quantity by many environmental factors inherent to a specific area, they can be an indicator of the potential problems weeds crops. In Valencia (Spain), rice is cultivated with continuous flooding during growing season, after harvesting, paddy fields flooded again winter. This study investigates fields’ soil seedbank this Mediterranean area effect winter on seedbank. Multispectral images from Sentinel-2 satellite were used characterise water level paddies Satellite facilitated characterisation fields. samples sixty-nine points distributed over 15,000 ha determine plots. The data spatially represented geographic information systems. species that contributed most Cyperus difformis L., important weed other such as Echinochloa sp. Leptochloa fusca subspecies. Other great contribution develop produce large small seeds, Lemna sp., Polypogon monspeliensis (L.) Desf., Nasturtium officinale R. Br. These interfere little or do not crop. revealed general, reduced density differences between species. Furthermore, influence different plant obtained well their distribution maps further step protected point view management crop, wetland.
