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.
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
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.
Claying involves adding and incorporating clay-rich subsoil into water repellent topsoil to overcome the repellence.
Using tillage to incorporate lime improves the rates of reaction and increases subsurface pH sooner than spreading lime on the surface alone.
Agricultural lime is any product that is used to increase the pH of soil. In Western Australia, the three main sources are limesand, limestone and dolomitic lime.
