Return Information Quality for Post-Harvest Evaluations

As the number of devices and services making use of accuracy ag data to assistant in choice making remains to raise, the significance of having top quality data is likewise boosting. Most producers comprehend the relevance of yield screen calibration for creating accurate yield quotes, yet there are other errors that can influence both the precision and the spatial stability of return information (in more details - 3d topography software). Spatial stability of return information becomes very crucial when being made use of to creating prescriptions for fertilizer and seeding. Spatial mistakes in return information become a problem when utilizing return maps to develop monitoring zones and subsequent input choices by area within an area. Taking the time to assess high quality and also getting rid of erroneous data guarantees prescriptions as well as various other maps based off return information are correct.

When processing yield data this wintertime, some mistakes to be conscious of consist of: header elevation setting, quick stop-start errors, flow delay setup, as well as header/ system size setup. Each of these errors will result in incorrect yield estimates affecting maps produced from yield maps. The complying with details several of the possible mistakes:

Incorrect header height setting

An incorrect header height setting can lead to information being gathered when the integrate is not collecting the plant. This mistake usually results in low or zero yield values being collected in headland or point-row areas while the integrate is turning. If this error is not acknowledged as well as attended to, the return approximates for areas that consist of cliff locations will certainly be undervalued as a result of added property being gauged with little or no added plant picked up. Number supplies an image where the enhancement of the turning data would ignore yield in these areas. It is suggested the turning data be removed prior to any kind of area or spatial evaluations be performed.

Number 1. Wrong header elevation establishing leading to information collection in cliff turning.

Quick Start-Stop Errors

The accuracy of the yield monitor calibration depends on consistent flow of material via the incorporate. Sudden changes ground rate (increasing or deaccelerating) cause locations where return quotes are incorrect. Typically yield is overestimated where the sudden stop occurred and then ignored until the material flow via the incorporate has time to ramp back up. Number 2 shows three areas where the combine was stopped quickly throughout soybean harvest. These data do represent the actual yield in this area and also need to be gotten rid of.

Number 2. Red yield points in the yield map show locations where the incorporate quit and after that restarted during soybean harvest. Getting rid of the stop-start mistake in facility of this map and after that interpolating to a grid changes the 50x50 feet grid worth for this area by 23 bu/ac (soybean yield).

Flow Hold-up setup

When the circulation delay setting is incorrect, it will cause each mass circulation quote being attributed to the wrong area in the field. This creates not just a spatial error, but also a mistake of yield when the combine's rate is transforming. This mistake is typically simplest to spot around the border of the area on the yield map, as shown in Figure 3. It is necessary to keep in mind that the data is offset for the whole size of the field and not only at the sides.

Number 3. The characteristic zig-zag pattern created when the circulation hold-up setting is incorrect.

Header width mistake

Having a precise estimate of the area being harvested is essential to having accurate return price quotes. An usual trouble takes place when the corn or platform header is not being operated at complete capacity and the header size setting is not upgraded to mirror that in the yield display. When this takes place, the amount of crop approximated is split over a larger location than in fact gathered resulting in an underestimation of return. These errors most commonly show up in return maps as straight lines down a pass or in fields with point-rows. One requires to either change the harvest width for these factors or eliminate from the map before evaluations. Number 4 presents a partial pass (e.g. partial header size) in soybeans where the header size was set to full-width generating reduced return estimates for this pass.
