Test results: the EDX technology in comparison
During comprehensive placement tests in 2010, different precision air seeders were compared whilst sowing maize. The objective of the test was to compare the placement quality of the new EDX precision air seeder with conventional machines from other manufacturers. The results show an obvious advantage in the EDX technology.
- Grain spacing along the row
For coefficient of variation (CoV), the measure for placement accuracy, the EDX comes off very well in comparison with conventional machines. At 15 km/h the CoV values for the EDX are virtually the same as with conventional machines at slower operational speeds.
- Placement targets
Across all operational speeds the EDX achieved the highest number of seeds placed at the target spacing. Even at 15 km/h the placement target values for the EDX were higher than the level of the compared machines working at much slower speeds.
