What truly is the purpose of a variable rate prescription? Wikipedia puts it as “the application of a material, such that the rate of application is based on the precise location, or qualities of the area that the material is being applied to.” Fairly complicated right? At Premier Crop we like to describe it as using your technology that your equipment already has to reallocate your inputs to a part of the field where your yield potential and return on investment are higher. Ever since variable rate application methods were introduced in the 1990s and on into the 2000s there have been a number of farmers who have strayed away from using variable rate technology because it “just doesn’t pay”. I can understand this mentality because there has never been a precision agriculture software that ties the agronomics to the economics. Was the increase in yield that we saw in that area of the field where more seed/fertilizer was applied enough to offset the cost of the inputs and provide a greater return? This is the type of question that led many to be non-believers in variable rate prescriptions.
