Our program of plant and tissue analysis during the growing season assures that our clients' fertility programs are working well and allows us to make any mid-season adjustments as necessary in macro and micro nutrient levels. Agro Engineering has developed potato variety-specific guidelines for tissue (petiole) sample results.
We're also now trialing a new type of plant sampling called sap sampling that draws information from the plants phloem, and gives us more information for better in season fertility recommendations.
