Have you been getting frustrated, because fertilizer, pheromones, and flown on chemicals will not enter into the system correctly. Here is the process on how to make sure that they are entered correctly.
The first step is to change the recording information to units if it is not already selected. When units is selected then N/A will show up in the per 100 and per tank columns, since these are not used in dry or unit appilications.
The next step is to uncheck the Est. Ac. box. Then enter the number of treated acres, and then enter the number of units appilied.
