Fallow weed management for broadacre cropping

Fallow weed detection and location on large broadacre crop paddocks for selective spraying using existing everyday spay rigs provided in collaboration with our industry partner InFarm.  

This involves the capture high resolution imagery that is processed using the latest Artificial Intelligent (AI) technology to detect small weeds within fallow paddocks on large broadacre cropping farms. Detected weeds are geolocated and a tractor ready file created that can be ingested via a USB into a standard variable rate spray rig. This then controls the nozzles or boom section to selectively spray the weed patches.  

The objective is for farmers to be able to reduce herbicide costs by up to 97.5%, and to be able to do this on large cropping properties quickly and efficiently with existing machinery.  

In cabin video (below) – points to note on the display are:

  1. Green spots on the display are unsprayed weeds coming up.
  2. Blues patched on the display are the weeds once sprayed.
  3. The spray nozzles can be seen on the bottom of the display with blue arrows turning on and off on each section of the boom.  

Benefits include

  • A reduction in herbicide costs of up to 97.5%.  
  • Improved spray productivity for large properties – being up to 2x faster for the spray rig to cover the ground area compared with other competitive ground-based technologies. 
  • Similar or lower cost per hectare than ground-based technology contractors. 
  • No large capital outlay required to setup a ground-based system, utilizing existing spray rigs. 
  • Provides detailed chemical spray coverage maps of a paddock each time for advance planning and for regulatory records. 
  • Reduced environmental impact of herbicides.

    Terrain modelling for land management  

    Data provided for our industry partner, InFarm, using aerial LiDAR surveys to produce high resolution bare earth (without vegetation) digital terrain models (DTM) that can be analysed to uncover the way water moves on terrain in detail.  

    By mapping catchments and water flow, we can see where water is leaving the production cycle and provide solutions to mitigate the losses. 

    Benefits include:

    1. Enhance water infiltration  
    2. Divert and repair erosion  
    3. Optimise water collection 
    4. Identify ideal dam location  
    5. Mitigate bog zones and flood prone areas  
    6. Best practice contouring  
    7. Best practice farm logistics  
    8. Quantify soil for melon hole repair
