Seed bed preparation and soil management history are thought to have a large impact on the efficacy of mechanical cultivation, but limited information is available on the mechanisms of these effects. In field trials, we tested how pre-plant bed preparation, historic compost use, and molasses applications affected soil surface characteristics and the efficacy of flextine cultivation. Contrary to expectations, historic compost and molasses application had little or no effect on the efficacy of fl…

Summary

Seed bed preparation and soil management history are thought to have a large impact on the efficacy of mechanical cultivation, but limited information is available on the mechanisms of these effects. In field trials, we tested how pre-plant bed preparation, historic compost use, and molasses applications affected soil surface characteristics and the efficacy of flextine cultivation. Contrary to expectations, historic compost and molasses application had little or no effect on the efficacy of flextine cultivation, and rolling beds prior to planting reduced flextine efficacy. Rolling beds resulted in lower soil surface roughness, but also increased soil penetrometer resistance, which was associated with reduced efficacy of cultivation. These surprising results highlight the importance of characterization of soil conditions in cultivation research.
