Do you have a flow meter, but are not sure how to use it to apply the specific amount of nitrogen from lagoon water called for by your nutrient management plan? Check out this new Excel spreadsheet from the University of California cooperative extension for help.
The tool allows users to easily calculate the flow rate or run time needed to apply just the right amount of lagoon nutrients using your flow meter and throttling valve.
If you don’t have a flow meter, a similar spreadsheet calculates how long to run the lagoon pump on each field or check to apply the amount your plan calls for.
