New technology on the horizon - "green-on-green"

Precision farming is continually evolving, with ongoing advancements in AI computer vision, specifically within the field of “green on greentechnology. In previous years, the “green on brown” technology was widespread. This system could identify weeds on the fallow fields and address them through spot spraying, relying on color differences to distinguish between weedy and clean zones. 

In contrast, “green on green” technology differentiates between weeds and cultivated plants based on leaf morphological characteristics and other visual factors. This system can detect weeds in green crops. 

In practice, this involves creating a weed map athrough AI analysis after the drone survey.  This map shows the weed species composition in the  area, providing farmers with precise information on the location of weeds. Armed with this data, farmers can make well-founded decisions on mixing chemicals, areas to treat and the pace of application depending on the infestation levels of different zones.  

In a recent survey of a pea (Pisum sativum) field, several  weed categories were identified: ragweed (Ambrosia artemiisifolia), common milkweed (Asclepias syriaca), jimsonweed (Datura stramonium), german chamomile (Matricaria recutita), amaranth family (Amaranthaceae sp.). 

One of our clients, a major player on the food market, approached Proofminder to help them  fight a significant jimsonweed issue. High resolution drone images were collected by our partner, a professional drone service provider in Hungary Drone Deer, uploaded to Proofminder’s platform and analyzed by Proofminder’s AI model Proofminder not only detected jimsonweed and provided the GPS coordinates of the weeds for precision spraying, but also identified and located the four other most common  weed species. This information enabled the client to plan accurate  weed management actions, only applying chemicals in the areas where it was necessary. Due to these actions, the client was able to significantly improve food safety  and reduce the cost of spraying  dramatically. Identifying different weed species and distinguishing between similar weeds in a dense and lush vegetation was previously challenging, however, Proofminder’s platform now provides never-before-seen accuracy in weed maps that can help you in making the best weed management decisions.

Proofminder strives to provide innovative, cost-effective, environmentally friendly, and time-saving solutions to farmers. 

How is this achieved? 

  • Chemical usage can be decreased by up to 70% through spot spraying. 
  • The cost of chemicals can be decreased. 
  • Resistant or harder-to-treat weeds can be identified, allowing for the targeted use of larger quantities of herbicides or more expensive chemicals. 
  • Machine operating costs can be optimized. 
  • Reduced fuel consumption leads to lower carbon dioxide emissions. 
  • Time and resources are saved by avoiding unnecessary spraying.  
  • Weed maps and spray logs allow year-to-year comparison. 
  • Tracking the presence of weeds during different spraying cycles becomes possible. We can tell which weeds are more difficult to treat or even resistant, and if any have freshly appeared.  
  • Based on the above, spraying times and rates can be optimized in different areas.
