06 Harvest weed seed control

Capture weed seed survivors at harvest using chaff lining, chaff tramlining, chaff carts, narrow windrow burning or weed seed impact mill. There are currently nine Harvest Weed Seed Control (HWSC) tools being used by Australian grain growers. All remove weed seeds at harvest but they come at a different capital cost, running cost and cost of nutrient removal. To compare these tools we must first consider the running cost, and then add the nutrient cost to get a realistic comparison.

WeedSmart’s Peter Newman has also put together a model on HWSC so you can calculate the cost of different HWSC options on your farm. You can download the model here.

Narrow Windrow Burning

This option is relatively easy to adopt and has good results for farmers. Some of the downsides to this option include it being time-consuming; the high level of nutrient removal and the risk of fire escapes to name a few.

Chaff lining

This cheap and simple solution involves creating a chaff chute which is attached to the back of the harvester to divert the chaff fraction (containing weed seeds) in a narrow row at the centre of the harvester instead of onto the tramlines, meaning it can also be used in non-CTF farming systems.
