relating planter downforce and soil strength
Soil & Tillage Research, 2018Co-Authors: Philip F Brune, Bradley J Ryan, Frank Technow, Brenton D MyersAbstract:Abstract Soil strength is a property that contributes to agricultural outcomes and describing related soil attributes. It is typically measured at low throughput with manual implements or approximated on-the-go with unique systems, limiting the robustness and broader applicability of data sets. This work assessed the viability of planter downforce as an on-the-go and relatively standardized means to collect soil strength data. Manually sampled soil mechanical and physical property data was collected and compared with planter downforce. Medium to high relationships were observed between planter downforce and vane shear strength (r 2 = 0.76), cone penetration resistance (r 2 = 0.67), and bulk density (r 2 = 0.78). These indicate planter downforce – a dataset extensively collected by modern Planters – has the potential to meaningfully describe distributions of soil strength in agricultural fields, and thereby serve as a useful soil informatics dataset to improve modeling of crop development and productivity.

LABORATORY AND FIELD TESTING OF SEED SPACING UNIFORMITY FOR SUGARBEET Planters
Applied Engineering in Agriculture, 2010Co-Authors: Jonathan W. Panning, Michael F. Kocher, John A. Smith, Stephen D. KachmanAbstract:Five planter configurations were evaluated for seed spacing uniformity at three field speeds using a seed location method in the field and a laboratory method involving an opto-electronic sensor system. Planter seed spacing uniformity was described using the Coefficient of Precision (CP3) measure. Results showed that CP3 measures determined using the laboratory test method were significantly different from those determined using the field test method. This indicated the laboratory test method cannot be used to predict planter seed spacing uniformity in the field. Seed spacing uniformity determined in laboratory tests was higher than, or equal to, seed spacing uniformity determined in field tests. This indicated the laboratory test method may be useful to screen out Planters or planter units with poor uniformity of seed metering. Field testing of the Planters that perform well in laboratory tests must be conducted to adequately determine the seed spacing uniformity of those Planters in the field. Results from laboratory and field tests could be useful in determining areas for improvement of Planters or planter units.

the role of field dust in pesticide drift when pesticide treated maize seeds are planted with vacuum type Planters
Pest Management Science, 2018Co-Authors: Arthur W Schaafsma, Victor Limayrios, Luis Gabriel ForeroAbstract:BACKGROUND Neonicotinoid-contaminated dust escaping pneumatic seeders causes exposure to non-target organisms such as pollinators. Two sources of dust have been reported: abrasion by talc which is added as seed lubricant during planting, and seed-to-seed abrasion occurring during seed handling, distribution and planting. We report a third important source that warrants remediation. Here, soil dust stirred up by Planters was found to enter the vacuum air intake near seed metering devices. RESULTS The mean quantity of dust collected from the exhaust of a commercial pneumatic planter over a number of field sites and situations was 46 g ha−1, ranging from 5.8 to 184.2 g ha−1. While the clothianidin concentration in exhaust dust declined with increasing quantity of dust, total clothianidin recovered increased linearly within the study parameters. Up to 2.4 g ha−1 of clothianidin was recovered from planter exhaust, representing approximately 12.6% of the active ingredient applied to seed. A similar pattern occurred in the laboratory on a single standing planter unit using diatomaceous earth as surrogate field dust. CONCLUSION Field dust in pneumatic metering systems contributes significantly to clothianidin contamination in planter exhaust by seed abrasion. Adding diatomaceous earth as surrogate field dust to the Heubach seed dust protocol accounted for field dust abrasion and distinguished anti-abrasive properties of seed treatments. © 2017 Society of Chemical Industry

development of an electro mechanic control system for seed metering unit of single seed corn Planters part i design and laboratory simulation
Computers and Electronics in Agriculture, 2018Co-Authors: Anil Cay, Habib Kocabiyik, Sahin MayAbstract:Abstract The performance of precision Planters is very important for attaining uniform seed spacing. While a planter is on work, undesired situations such as spinning and slipping on ground wheel, vibration, seizing and jamming on the chain-sprocket systems may occur during the transfer of the motion from the ground wheel to the seed-metering unit especially at high operating speeds. In order to overcome these problems, it was aimed to develop an electro-mechanic drive system (EMDS) for seed metering units of a classic single seed planter. The performances of the EMDS and the classic drive system (CDS) were tested at three different operating speeds (vf) (5, 7.5, 10 km/h) and ten different seed spacing (zt) from 6 to 29.3 cm at laboratory. Both systems were compared regarding to the seed spacing uniformity. When the EMDS was used, the quality of feed index (Iqf), multiple index (Imult), miss index (Imiss) and precision index (Ip) were ranged as such: 2.91–95.36%, 0–1.73%, 4.45–97.09% and 8.79–22.14%, respectively. At the test of the CDS, the performance indices varied as such: Iqf 2.09–98.55%, Imult 0–0.36% and Imiss 1.09–97.91%, Ip 5.79–20.92%. Seed spacing uniformities were found as “good” and “moderate” for both systems. Average seed spacing values obtained from the EMDS were found to be closer to the theoretical seed spacing values compared with that obtained from the CDS. EMDS enabled the suggested optimum seeding rate, a quick and simple setting possibility, synchronize and real-time control, the ability to work under higher speeds, individual movement and control for each metering unit. However, EMDS should be tested to determine the success of the system in practice. Therefore, the field performance of EMDS with respect to plant spacing uniformity and operational parameters (variation among rows, fuel consumption and negative slippage) were examined in the following part of this study (Part II: Field Performance).
