Is Seed Rate an important property to capture during As-Planted in the context of Traceability? Answer=Yes. #1

Open dubnemo opened 1 year ago

For variable rate planting operations where the density of corn is thicker than other areas, when planter models have one planter box per row, some boxes will empty sooner; i.e., available volume measure will be different for each planter box. One would argue that if sensors were available to capture the remaining volume (sonic, etc), we would know the TRU's ContainerState. And if it was required, it seems it would be an array of point with associated rate values .

Seed Rate also has importance for nutritional value of harvested commodity, as there is not enough nutrients in the soil to go around.

@jtevis @ekwallace @crakerb-ship-it Does ADAPT have unit of measure for seed rate?

PLS pounds per acre

NRCS: A seeding rate is expressed in PLS pounds per acre and is based on planting a Pre-determined number of Live Seed per square foot to achieve a specific plant density.

ADAPT has a couple options for as-applied seed rate in the data definitions that would vary by seed/planter meter type, one is count per area, the other mass per area, also there is a volume per area, but I am not aware of any seeding machines that document metering that way. Drills and air seeders essentially meter by volume but are calibrated by weight...

All the values in ADAPT have Target, Actual, and Control, I assume for traceability Actual would be the only one we are interested in.

Wow, it seems that we need to educate a lot of agronomists on the new standard, arcane unit of measures. For example, seeds/acre is a nice way.

In Canada and Europe, I was seeing weight kg/hectre vs count. Why weight? That is not smart. It gives very limited information related to seed density on the field, requiring you do know seed size and mass density.

"definitionCode": "AppliedCountPerAreaActual" -> typeCode "unitOfMeasureCode": "count1ha-1" -> unitCode

It depends on how you define seeding rate. Seeds/time is not of much value but the result measured in seeds/area is important an important parameter. However, for most precision planters this is already recorded. Usually both the intended and actual rates are recorded.

In general, since most "precision" planters are already recording this data I don't think it is necessary to include in the CTE.
