Client Testimonials

"Since installing Soil Moisture probes on our property, the guess work of watering has been replaced with certainty. We are now adequately watering our lucerne crops at the optimum time to increase crop growth and improve yields."

"Alpha Group’s Irrigation Monitoring Service has become an integral part of our overall irrigation system. We have been able to use minimum water for a maximum area whilst operating on a range of soil types, including quite shallow limestone. This has enabled us to achieve efficient and timely watering which in turn has lead to excellent seed yields, with good profitability and sustainability going forward."
