The ASABE S658 standard is divided into three parts:
ASABE S658-1, Singulating Seeding Equipment Test Methods Part 1: General Information
ASABE S658-2, Singulating Seeding Equipment Test Methods Part 2: Monitoring Systems Performance
ASABE S658-3, Singulating Seeding Equipment Test Methods Part 3: Seed Spacing Performance

The scope of this part of the S658 standard series is to define a test method of the monitoring system from the row unit’s seed sensing point to the end user interface display or farm management system.

An Excel workbook with the report form in which planter monitor information can be entered (Annex G), and the table in which planter monitor performance results can be entered (Annex D, Table D.1, with minor calculations performed automatically) can be downloaded from https://www.asabe.org/S658.

Instructions and information for using the workbook are in the Instructions sheet of the workbook.

This standard allows for evaluation of machine performance or comparison of data within a given facility. This type of comparison testing can only be possible if all factors (i.e. test process, test setup, test methods, seed characteristics, instrumentation, and environmental effects) are managed, administered, and replicated exactly the same and therefore results are only valid for comparison within a test location. The standard is anticipated to be performed within a laboratory environment facility and not in an actual field.

Note: All Annexes referenced within the ASABE S658 standard series are located in part one, ASABE S658-1, Singulating Seeding Equipment Test Methods Part 1: General Information.
