SoluSAMPLER
Features
- Incorporates SARDI soil water extraction technologies.
- A custom designed ceramic cup, available with different pore sizes to suit the soil type it is used in.
- Once under vacuum, the extractor draws moisture from the surrounding soil and stores it in the inert ceramic cup awaiting collection and analysis.
- The solution extracted into the cup retains its ionic integrity as the ceramic does not influence the solutes.
- The ceramic cup is glued to a length of 40 millimetre PVC conduit, housing an extraction tube with a two way stopcock.
- Complements probes with TriSCAN™ sensors, enabling precise site specific analysis of soil pore water salinity content.
- Soil pore water samples can be extracted from the ceramic cup using a syringe and analyzed using a Portable Electrical Conductivity (EC) Meter, nitrate strips or laboratory analysis.
Benefits
- Improve crop quality and yield by using soil solution monitoring to track salinity and nitrate levels in the soil.
- Reduce the risk of harmful salt accumulation in the root zone due to irrigation.
- Measurements can detect salt before visual symptoms are seen.
- Minimise the risk of serious health consequences caused by nitrates leaching into groundwater.

Satellite Spectral Imagery

Satellite Spectral Imagery
NDVI images are satellite images taken throughout cropping season. This is an optional service, like the Weather forecasting service MeteoBlue. NDVI measures the state of plant health based on how the plant reflects light at certain frequencies. Other images available include NDRE, MSAVI, ReCl and NDMI. Our offerings provide you with insights at 10m x 10m granularity on a frequent basis.
As customers, you can see 1-2 high resolution images per week of your crops tracking over- or under performance. This will help you tackle irrigation management, fertigation practices, crop diseases and irrigation system performance issues.
Furthermore, building up this data over time is an investment that you can realise by improving overall yield quantity or quality, reducing input costs, or expanding into new varietals or paddocks. Up to 18 months of historical data can also be accessed.
