Benefits of precision spraying

Conserve herbicide

  • Experiments have shown that a typical wheat or barley farm can reduce use of herbicide by 40 – 50 %.
  • Assuming that herbicide costs NOK 25 / USD 3 / EUR 2.6 per 1000 m², this saves NOK 30 000 / USD 3 600 / EUR 3 150 per year, on a 3 km² farm.

Increase yields

  • Experiments have shown that unsprayed fields of wheat and barley have on average 6 – 7 % greater yields.
  • This increased yield gives an average of NOK 100 / USD 12 / EUR 10.5 extra income per 1000 m².
  • When the DAT system reduces herbicide use by, on average 40 %, a 3 km² farm increases their income by NOK 120 000 / USD 14 600 / EUR 12 650 per year.

Save time and the environment

  • Reducing herbicide use helps you run your farm in a more sustainable manner by also saving you time and eliminating excess herbicide in the environment.
  • The variables in this calculation vary, but we invite you to make your own calculations with our cost-savings spreadsheet.
