Rodale compares their own experimental farm, not organic yields on real commercial organic farms (many of which are run for more than 5 years). Their conventional yield is also on their farm, not real conventional farms.
Edit: Looking a bit further rodale has rest years that they don’t count for their organic fields. 25% of the years they literally don’t grow anything on a given plot, but they only compare the growth years.
- sdoering 6y agoIt is a scientific institute. So it isn't an organic farm either. So I am not sure if this argument applies in any direction. It I am totally aware of studies like Verena Seufert et al. showing reduced yields between 5 to 39% depending on the context and used methodologies. Edit: Regarding rest years. At least were I live both, organic or non organic farmers do that. Not sure how it is in other parts of the world.
