A participative network of organic and conventional crop farms in the Seine Basin (France) for evaluating nitrate leaching and yield performance
A collaborative study was set up, involving a network of volunteer farmers, to investigate NO3− leaching with ceramic cups (90 cm deep) on whole crop rotations of organic (OF) and conventional (CF) commercial farms in the Seine Basin. The water inflows calculated ranged from 86 to 190 mm depending o...

| Tóm tắt: | A collaborative study was set up, involving a network of volunteer farmers, to investigate NO3− leaching with ceramic cups (90 cm deep) on whole crop rotations of organic (OF) and conventional (CF) commercial farms in the Seine Basin. The water inflows calculated ranged from 86 to 190 mm depending on the year for the 4-month drainage period. The amounts of N leached were on average 23% lower in OF (12.5 ± 2.9 kg N ha− 1 yr− 1) than in CF systems (16.2 ± 6.3 kg N ha− 1 yr− 1). Concerning farming practices, the main impacting factors were the use of EOM in fall, the lack of catch crops before spring, and the proportion of legumes in the rotation. Overall, this wide collaborative network highlights good and innovative practices by CF and OF farmers attempting to decrease NO3− in groundwater. |
