GreenSeeker®

Putting the RIGHT AMOUNT IN THE RIGHT PLACE AT THE RIGHT TIME

GreenSeeker®  optical sensor technology enables you to measure, in real time,  a crop's nitrogen levels and variably rate  apply the "prescribed" nitrogen requirements. GreenSeeker® also predicts yield potential for the crop using the agronomic vegetative index (NDVI). The nitrogen recommendation is based on in-season yield potential and the responsiveness of the crop to nitrogen.

GreenSeeker® enables you to take plant health and vigor measurements on your schedule!No longer do you have to depend upon cloud-free days for satellite images, or pay the high cost of aerial images. GreenSeeker® is similar to satellite and aerial imagery zone management imagery programmes, however,it is in real time.

You can also collect data during existing farming operations such as spraying, cultivation and mowing. These images can by used to create management zones, identify pest and disease problems, evaluate drainage systems efficacy, modifying soil sampling strategies, monitor and modify irrigation schedules, determine optimum harvesting dates and make variable rate prescription maps. Numerous NDVI readings are averaged across each zone and a "prescription" is written. The controller modifies the rate for each ensuing zone. GreenSeeker® works with most variable rate controller and delivery systems. The sensors can be mounted on booms of various configurations on most sprayers and spreaders.

GreenSeeker® allows application of liquid UAN, UREA and NH3 fertilisers. It can also be used to variably apply a variety of other agro-chemicals such as defoliants and plant growth regulators.

Key Benefits of GreenSeeker®

  • Fast and precise optical sensing .
  • Current conditions determine fertiliser rates.
  • Collect crop data during existing farming operations.
  • Addresses field variablilty,putting the right amount in the right place.
  • Works night or day.
  • Significantly reduce environmental impact.
  • Reduce in-crop  fertiliser and input costs.
  • One time investment with no annual  costs.
  • Simple to install and calibrate and straight forward to operate.

How GreenSeeker® works

GreenSeeker allows on-the go management of top or side-dress nitrogen. The sensor's light emitting diodes (LED) generate red and near infrared (NIR) light.The light generated is reflected off the crop and measures by a photodiode located at the front of the sensor head.

  1. Sensors scans the crop using LED lights.
  2. Optically sense health using vegetative index (NDVI).
  3. Predicts yield potential.
  4. Prescribes optimum zone nitrogen rate.
  5. Delivers variable rate application.
  6. Zone size 0.1 to 0.2 ha (dependant on speed and controller).
  7. Utilises existing controller and plumbing.
  8. Can apply liquid UAN, UREA and NH3.

    Features of GreenSeeker®

    • Weatherproof.
    • Operational night or day.
    • Modular system that can be added to.
    • Plug and play with existing rate controllers.
    • Capable of speeds up to 25km/hr.

WeedSeeker

WeedSeeker® technology uses sensors and nozzles spaced at 300mm - 380mm apart.This is due to the narrower field of view associated with the WeedSeeker® sensors compared to a 500mm spacing on a standard boom. WeedSeeker® can also be used to selectively apply fungicides, insecticides, fertilisers and other inputs to targeted plants instead of ‘weeds’ in a range of applications.

Smart - N

In 2010 the Precision Pastoral Nutrient Management Group was set up and gained funding through MAF-SFF to look at the viability of the Snmart-N Fertiliser Application system. Nitrogen leaching from dairy pasture is recognised as the number one environmental problem facing our dairy industry, and cow urine patches are the main culprit.

EM Soil Surveys

Soils vary across farms and within paddocks but the practice has been to manage these as though variations did not exist – applying a consistent rate of fertiliser across a paddock being an example. The EM38-MK2 provides measurement of both quad-phase and in-phase components, within two distinct depth ranges, all simultaneously, without any requirement for soil-to-instrument contact.
