Optimizing variable rate nitrogen fertilizer application in fields with spatial variability

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.
