Phosphorus inputs in grazing and cropping enterprises are still an essential part of productive farms on the tablelands and slopes. With phosphorus being a finite resource, scientists across the country like Dr Richard Simpson have been searching for improvements in the P-balance of agricultural soils.Local landholders are invited to attend a Nutrient Cycling in Soils workshop on Thursday, March 12 in Blayney.
The Central Tablelands Local Land Services is hosting Dr Richard Simpson, among five expert speakers who will talk about a range of soil fertility investment options.
Dr Simpson’s topic, ‘The fate of phosphorus applied to pasture – implications for effective use of fertiliser’ will headline the event in Blayney.
Phosphorus inputs in grazing and cropping enterprises are still an essential part of productive farms on the tablelands and slopes. With phosphorus being a finite resource, scientists across the country like Dr Richard Simpson have been searching for improvements in the P-balance of agricultural soils.
“Farmers recognise that phosphorus is a finite resource and that the cost of fertiliser has risen steeply over the last decade, but this is not a reason to abandon its use,” Dr Simpson said.
“There are ways of stretching it out further, increasing its efficiency. Understanding the target soil test value for managing soil fertility on your farm and the emerging possibility of using plants that are more productive in low phosphorus soils, are ways to improve the P-balance of pastures.
“Traits that improve the plant’s ability to forage for nutrients include long fine roots, branching, root hairs and mycorrhizal associations.”
Phil Cranney, Senior Land Services Officer for pastures is encouraging farmers to take advantage of access to Dr Simpson and other speakers.
“This is a great opportunity to hear directly from a leading CSIRO research scientist about a subject that can deliver benefits now and will undoubtedly have increasing impact into the future,” he said.
The information session will begin at 9am in the Blayney Shire Community Centre on 41 Church Street.
Presentations will finish at 12:30 pm and there will be a short open panel discussion till lunch, which will be served at 1pm.
There is no cost, but for catering purposes you must RSVP. For more information or to RSVP, please call Phil Cranney, Senior Land Services Officer for Pastures (0458 745 478 or email [email protected]).
