High tech for maximum quality: checking seed in the computed tomography scanner
In the lab with Sylvia Letsch
Top-quality seed is the key to achieving the very best yields. One of the central requirements for seed to produce high-yielding plants is for it to contain a healthy embryo. But experts can’t tell that from the outside of a seed. An ideal solution would be if they were able to look directly inside the sugarbeet seeds, which are just a few millimeters in size. And KWS’ seed experts enable such an examination with a 3D computed tomography scanner.

A look at the sample: Every single seed is recorded in the analysis.

60 samples with a total of 18,000 seeds at one stroke.

The samples are placed in the scanner. The detector is on the left wall and the radiation source is on the right.

Large vibrating screeners are used to help prepare the seed. Its quality is repeatedly examined using the computed tomography scanner.

The upshot is the pellet: the finished seed.

The seed then goes to the packaging line.

That’s how things should end up looking: no sugarbeet twins or gaps in the field due to empty seeds.
