Efficiency, substitution and redesign is one framework used to cut reliance on costly fertiliser inputs. Emma Gillbard speaks to a plant and soil expert for advice on how this can be achieved.Farmers are seeking ways to cut artificial fertiliser rates as prices skyrocket, and one Canadian expert has developed a three-step approach to achieve this.Cropping is currently based on classic agronomic disciplines, coupled with high inputs and good returns. However, by improving efficiency, substituting for alternatives and redesigning agricultural systems with the inclusion of legumes, farmers are ableto reduce reliance on costly fertilisers, explains Joel Williams, independent plant and soil health scientist."Irrespective of farming type and starting point, we can all benefit from using this framework to decouple from inputs. This technique enables us to conceptualise the transition from conventional farming practices to a more regenerative approach," he says.
