Water quality is monitored through periodic sampling at the upper and lower limits of rivers on properties. Irrigation systems are progressively being upgraded to those that are more efficient, moving away from high water usage systems, as part of the Group’s continuous improvement programme. The increased use of probes to measure soil moisture as well as the interpretation of the results by irrigation specialists have resulted in detailed irrigation scheduling, impacting positively with a reduction in both water and electricity consumption.

Rather than rely on perennial rivers, it is an objective of Crookes Brothers to store sufficient water to meet seasonal demands. In an environment where water availability is critical, having sufficient water allows the Group to manage crop production more effectively. To this end, each farming unit has developed an extensive network of dams and pipelines.
