Potential yield was estimated by a modified French and Schultz approach using monthly rainfall for each site and season... Exchangeable cations were measured on prewashed samples because many subsoils were saline (EC 1:5 higher than 0.5 dS/m)... Most sites showed no yield increase in the season of application...

Growers have been busy in recent weeks applying lime to paddocks as part of ongoing efforts to overcome soil acidity and maximise their farm's potential... There is no doubt that lime can improve yields on acidic soils and is a preventative treatment to maintain soil pH at acceptable levels... "In the trials we assessed whether investment in fertiliser needs to be cut to achieve a profit from lime incorporation and, overall, the answer was no...

Management of subsoil acidity and compaction using a combination of lime, deep ripping and controlled traffic Stephen Davies, Chris Gazey, Breanne Best and David Gartner, Department of Agriculture and Food, Western Australia.. The management of carbon can easily be promoted within the context of retaining both a profitable and viable farming system... A number of questions remain in relation to carbon offsets in agriculture and many of the opportunities and risks are unknown at this point in time...

Grain grower Kym Curnow estimates variable rate technology (VRT) has saved his business more than $117,000 over three years by allowing him to target inputs to soil type on his Western Australian farm... We'd just finished applying a blanket rate of gypsum over everything and the paddocks still weren't performing," he says... Before moving to VRT, his standard approach was to apply a blanket application of 14kg/ha of phosphorus across his entire farm...

Gypsum applied to responsive soils along Western Australia's south coast has improved water use efficiency (WUE) - the amount of grain produced from a given amount of rainfall... With results restricted to certain soils, growers will need to test their soil to determine whether it is responsive to gypsum... Gypsum counteracts sodic soils by reducing clay dispersion, which improves soil structure and drainage and reduces waterlogging...
