Soil Bacteriome Shifts along a Cultivation Gradient in Southwestern Spanish Wetlands.

ABSTRACT: Understanding how long-term agricultural practices affect soil bacteriome is essential for sustainable land management. In the Guadalquivir Marshes of southwestern Spain, which encompass both Doñana National Park and one of Europe's most productive rice cultivation areas, decades of rice farming have transformed natural wetlands into artificial agroecosystems. Although bacterial degradation in cultivated soils has been previously suggested, comparative analyses between rice paddies and adjacent natural wetlands remain scarce.Here, we characterized the soil bacteriome across a cultivation gradient by comparing undisturbed natural marshes, within Doñana National Park, with rice fields cultivated for 25 years (Cantarita) and 80 years (Mínima 2).
