What are the rate/rate unit and product rate/product rate unit fields in the ARM Treatment editor used for?

The ARM Rate/Unit treatment fields are also known as “standard” rate/unit fields. These two fields must be filled in before ARM can print a Spray/Seeding Plan report. Other key treatment fields that influence calculations on a spray/seeding plan report are the Form Conc and Form Type fields. The Other Rate/Unit fields are not required to produce either report.

The Other Rate/Unit treatment fields are also known as “alternative” rate/unit fields. These two fields were introduced in standard study definitions in ARM 6. Special programming is included to calculate the Other (alternative) Rate when the Rate (standard), Unit, and Other Rate Unit fields contain an entry. The Plot Signs report also includes an option to print signs with the Other Rate/Unit information, in case these contain product rates that are more useful to print on plot signs for a field tour.

The following shows an ARM treatment editor from an example study.

This example study illustrates how a researcher may enter Rates (standard) based on metric treatment units but also express the Other Rates in US treatment units. The rate units used by ARM (US or Metric) are determined by the setting on the Treatment tab of the Settings window (Window, Settings, Treatment).

The first treatment entered in the example study illustrates a treatment entered with the “standard” Rate/Unit as 3.5 KG A /HA. The “alternative” Other Rate Unit is defined as PT/A (US). ARM calculates the 6 Other Rate shown in the example study after the following have been entered:

1. Form Conc
2. Conc Unit
3. Form Type
4. Rate
5. Rate Unit
6. Other Rate Unit
