Green on green case study: Precision weed management

Precision weed management is where optical sensors and remote and sensor weed mapping systems are used to target weeds and therefore cut herbicide costs. The technology is becoming more widely available, which is why GRDC is investing in a series of case studies, to explore the benefits and costs related to these technologies. With green on brown systems, weeds can be detected in a fallow field. And now there's also green on green technology, which uses an algorithm to differentiate between weeds and crops. Tim Rethus operates a zero till cropping business in Horsham in Victoria's Wimmera region. Tim's invested in both green on brown and green on green technology. We caught up with Tim to find out more about his decision to integrate these systems into his farming practices, and whether he thinks the return on investment has been worth it.  Contact: Tim Rethus, Grower  [e-mail]    More in Precision weed management series:   Video, Green on green case study  Podcast, Green on brown case study  Video, Green on brown case study  Podcast, Drone weed mapping case study  Video, Drone weed mapping case study    Project Investment Code: SRE2310-001SAX  Learn more about your ad choices.
