Track your leaf and soil analysis reports on an individual block/patch basis. This information can be graphed and compared to application rates of NPK etc. for the same period.

Every time fertilizer is applied either as a dry application or by fertigation or folia spray, GrowData is tracking up to 13 elements.  Simply call up a report for the period of time covered since the last analysis to compare the quantities applied to the take up rate as reflected in the soil or leaf analysis.
