Technology on the rise

Sam Trengove.SPAA (Precision Agriculture Australia) committee member Sam Trengove (pictured) demonstrated the varied possibilities for new technology at the recent Mallee Sustainable Farming (MSFP) field day at Ouyen.

Mr Trengove said there were good applications for technology such as crop sensors, which he said could either be used for weed or nutrition management.

He said the sensors, which are still reasonably expensive, but coming down in price with technology improvements, were particularly good for identifying weeds in canola and pulse crops.

“In cereals, the crops tend to grow a bit fast, so it is hard to isolate the weeds, but you can do it successfully in oilseeds and pulses early in the season.”

He said it could also be used to assess nutrition needs, although farmers needed to make sure that crop discolouration was due to a nitrogen deficiency and not another issue.

Mr Trengove said one of the advantages of the crop sensors was that they had better resolution than human eyes.

“You can pick up some things with the sensors that you couldn’t just by doing a visual inspection.”
