This fact sheet is drawn from the RIRDC publication "An Alternative to Border Check Irrigation: Comparison of border check to drop tube centre pivot irrigation for lucerne irrigated with saline water" (RIRDC publication no. 08/014).
In response to a decline in the quality and availability of irrigation water and changing water allocation policy, the lucerne seed industry recognised the need to evaluate alternative irrigation systems.
The research provides numbers and observations on a ‘real life’ comparison of drop tube centre pivot and border check irrigation of lucerne seed production systems. The information gained can be used by growers to evaluate their current irrigation methods and assess future investment in the conversion of existing irrigation systems or the development of new irrigation fields.
