Recordkeeping Tools for GPM + Run Time
This field record sheet has a place to record irrigation run times, pond level, and weather information for each application when you use the gpm + run time or pond drop method. There is also a place to write targeting information if you want to apply the lagoon water in only part of the irrigation in order to put on a specific application rate.
You have several options for managing your data once the application is complete. While many operators choose to hire a service to calculate application rates for compliance purposes, doing the calculations yourself is easy and gives feedback in time to make in-season adjustments.
If you are most comfortable doing the calculations by hand, here are tools to make this easy.
Keeping a running total of applied nutrients is easy using these Excel spreadsheets. Use the information to make management decisions that will help you get the best crop yields by making in-season adjustments as needed and also there will be no surprises when it is time to prepare your annual report to the water board.
