Eric Koetz has over 20 years experience working in crop and pasture agronomy in southern NSW farming systems. He joined NSW DPI in 1996 after working with CSIRO from 1990 to 1996 on break crops and nitrogen management of cereals.
With NSW DPI, Eric initially worked on lucerne establishment in mixed-farming systems and evaluating a range of grasses (native and exotic) for low rainfall environments.
From 2000, he worked on integrated weed management including six years with the CRC for Australian Weed Management.
Eric’s research from 2008 to 2012 focused on herbicide resistance and involved three surveys across southern and central NSW identifying resistance levels to the major herbicide groups.
From 2012 to 2014, Eric was responsible for the pulse agronomy trials in southern NSW assessing the use of brown manuring in cropping systems and its role in controlling resistant weeds as well as the benefits of increased nitrogen and soil water from manured pulses to the following crops.
Eric has spent the past two years as a Research Agronomist working on cereals in Southern Farming Systems. Eric’s current role is as a weeds agronomist in cotton farming systems at the Wagga Wagga Agricultural Institute.
