Published by the American Society of Agricultural and Biological Engineers, St. Joseph, Michigan www.asabe.org ASAE ASABE S658-3 December 2023Keywords: Calculated in-furrow seed spacing, Corrected miss, Corrected multiple, Corrected spacing, Distribution, Doubles, Flow rate, Field speed, Meter spacing, Metering, Miss, Monitoring, Multiples, Orientation, Performance, Planter, Population, Row spacing, Row unit, Seed, Seed meter, Seed rate, Seed sensor, Seed size, Seed spacing, Seeder, Simulated, Singulate, Singulation, Skips, Slope, Spacing deviation, Trajectory position, True miss, True multiple. 1 Scope 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 for measuring the predicted performance of seed placement within the in-ground state (seed furrow) just after seed is dispensed from the row unit without accounting for the various dynamic effects after release from the seed delivery system. An Excel workbook in which row unit test data can be entered, and which will perform the necessary calculations and copy the results into the report documents and prepare the necessary graphs can be downloaded from https://www.asabe.org/S658. Instructions and information for using the workbook are in the Instructions tab of the workbook. This standard allows for evaluation of machine performance or comparison of results 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.
