The Challenge
Agronomic research and knowledge to develop variable rate fertilizer (VRF) prescription maps is lacking for the Canadian prairies.
The Project
Correlate crop yield response to nitrogen fertilizer rates from fields across Alberta with variable landscape through various physical and chemical soil and topographic factors.
The Results
With the cost of equipment and consulting, immediate future for VRF is not economically beneficial.
Grower Benefits
Alberta producers can save their money on VRF equipment and consulting/application until technology further develops to be cost effective.
