Incorporating SARDI Soil Water Extraction Technologies™
The Sentek SoluSAMPLER is a soil solution sampler that draws moisture from the surrounding soil and stores it in an inert ceramic cup, awaiting collection and analysis. It is the ideal complement to the TriSCAN sensor, enabling precise site specific analysis of soil pore water salinity content.
Sentek SoluSAMPLER types
Low Flow - suitable for most applications High Flow - suitable for light texture and moist soils (for rapid sampling)
Â
Sample Analysis
Samples of soil pore water are extracted from the ceramic cup using a syringe. Analysis of the water can be carried out by:
portable Electrical Conductivity (EC) meter
nitrate strips
laboratory analysis
Salinity and Nitrate Monitoring
Salinity and nitrate monitoring is important as:
saline water can reduce crop quality and yield
irrigation efficiency may lead to an increased risk of harmful salt accumulation in the rootzone
measurement can detect salt before visual symptoms are seen
nitrate levels are important for crop yields
nitrate leaching into groundwater can have serious health consequences
