Valley Irrigation is the worldwide leader in precision irrigation. The Valley brand of center pivot, linear, and corner equipment provides solutions for conserving water and meeting the growing demand for food. The center pivot is much more than an irrigation machine. Sharing the intelligence between connected field devices, the pivot, and the integration of data science and machine learning lets you detect and receive critical information to improve crop precision, which results in greater returns – all while using fewer inputs and resources.
Pastega Holdings have various sugar cane farms located in Eaton southwest of Mackay. The family have been progressively taking their farming practices into the 21st century and moving their irrigation to Valley pivot systems allowing water, time and electricity savings. They believe that personal time with their families is very important so having a fully automated irrigation system that can be operated via their phone from anywhere in the world was a huge benefit.
