Interactive tool for farmers to diversify high-latitude cereal-dominated crop rotations

Abstract

Agricultural landscapes have become more intensive and monotonous, which may further increase biodiversity loss. Even though Finnish rural landscapes are often heterogeneous, crop choices and rotations lack diversity. The aim of this study was to develop an interactive, multi-step crop rotation tool, which acknowledges farmer’s preferences in land allocation for different crops depending on farm and field parcel characteristics. The tool was developed to provide as diverse a 5-year crop rotation plan as possible on the field parcel scale for the farmer’s consideration. The tool is flexible and interactive in the sense that it allows a farmer to include or exclude crops and spatially and temporally rearrange them to improve farming logistics. The tool was tested in southern-western Finland with the highest potential for diverse crop choices and sequencing. Test-runs indicated that the tool was powerful in proposing diversified crop rotations: the shares of current monotonous cereal-based rotations collapsed. The final diversification plan always lies in the farmer’s hands, who may exclude crop choices and even end up in cereal monoculture rotations. The tool provides estimates on farm economics for each step of the planning process. The tool will be available for all Finnish farmers (∼48,000) on the EconomyDoctor-portal with personal access only and the background information is automatically updated annually.
