Soil organic carbon (SOC) is inherently low in Western Australian soils – limited by climate and soil type – with some potential to increase through management.
Western Australian grain growers are set to reap the rewards of a significant investment in new soil nutrition research that will boost crop production and reduce fertiliser costs.
The aim of carbon farming is to sequester more carbon and reduce greenhouse gas emissions, as part of Australia's response to climate change.
Barley growers attending a field walk and spring forum this week will hear about the latest research trials undertaken by the Department of Primary Industries and Regional Development.
Carbon farming is the agricultural practices or land use to increase carbon stored in the soil and vegetation (sequestration) and to reduce greenhouse gas emissions from livestock, soil or vegetati
Claying involves adding and incorporating clay-rich subsoil into water repellent topsoil to overcome the repellence.
The effect of mechanical incorporation of different lime rates on crop yield and subsurface pH was observed four seasons after application.
Mechanical incorporation of different lime rates using offset disc, Grizzly Tiny offsets® and deep ripping treatments were tested.
Amelioration of soil pH in poor soil patches in paddocks was tested using lime application and deep ripping treatments.
Mechanical incorporation of different lime rates using Grizzly Tiny offset® plough, deep ripping and cultivator points were tested.
