Put data behind seed wellbeing!

We at Bayer are looking for seed sized sensor solutions that monitor soil properties relevant for seed germination and early growth.

Within our SeedSensor challenge seven finalist teams were asked to plant an environmentally friendly SeedSensor, and start data driven yield optimization when seeds hit the ground.

Thanks to the teams from all over the world who gave their best with their innovative sensor solutions and made this virtual challenge so interesting and so much fun.

Congratulations to all of you!

Look forward to our next Grants4Tech challenge that will be posted here soon.


Build a seed sized sensor solution that monitors relevant soil properties for seed germination and growth. To be of practical use, SeedSensors need to be environmentally friendly, easy to use, and small.

The Opportunity

Today data driven field management starts the moment plants emerge. Why not earlier? Why is it so hard to sense below the surface? Soil sensors have a couple of disadvantages. They require a dedicated effort to plant and return data of just one spot. How to overcome this limitation? Make them small so that they fit in planters, are planted without additional effort, and distribute many of these sensors over the field. A mesh of sensors will provide a good overview of the soil properties close to every seed.

Your SeedSensor solution should cover following aspects:

  1. Measure relevant parameters accurately
    Parameters like temperature and moisture need to be measured. Show us also further parameters that could be of interest for us.
  2. Be as small as possible, preferably of the size of a seed
    Present us a sensor that can be put into the soil using a corn planter. The smaller the sensor, the better!
  3. Offer robust and practical solution
    Data collected by the SeedSensor should be transmitted successfully to a receiver device. Make your sensor independent of external power supply.
  4. Environmental friendliness
    Your solution needs to be either fully biodegradable, reusable, or recyclable.

The applications submitted by the entrants / entrant teams should cover these features as far as available. We are also interested in innovative partial solutions.
