Chaff Deck Case Study

Chaff Decking Paddock Demonstration Update

By Tim Bartimote | LLS Cropping Officer

For the last two seasons (2019, 2020) Local Land Services has been funded through the GRDC (Grains Research and Development Corporation) to undertake in-field demonstrations of Harvest Weed Seed Control (HWSC) around Gilgandra and Parkes.

This project aims to demonstrate the importance of integrated weed management to maintain adequate long term weed control and minimise herbicide resistance.

These demonstration sites focused on the use of chaff decks as a viable option for ARG weed seed management. This chaff deck method aims to capture weed seeds in the chaff as they pass through the header by separating it from the straw. Chaff is then directed and compiled on the wheel tracks.

It is primarily used in operations where a Controlled Traffic Farming (CTF) system is in operation.
