A series of field experiments have been established across the grainbelt in recent months as part of a new project that aims to increase the benefits and profitability generated by soil amelioratio
Growers in low rainfall areas with predominantly acidic soils have the potential to increase wheat yields by up to 30 per cent by combining lime and gypsum applications to their soils.
The innovative use of drones to precisely assess soil erosion will save time and money for WA growers.
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 Department of Primary Industries and Regional Development will contribute to conferences on soil health by highlighting research undertaken on a range of practices to overcome soil constraints
Soil water repellence is caused by an accumulation of waxy organic matter in the soil surface. It is worse in sandy textured topsoils.
Claying involves adding and incorporating clay-rich subsoil into water repellent topsoil to overcome the repellence.
One-off soil inversion results in the complete burial of the water repellent topsoil in a layer typically at a depth of 15–35cm, and brings to the surface a layer of wettable subsoil.
Waterlogging in the higher rainfall areas (more than 450mm) of South West Western Australian crops and pastures is a common cause of reduced plant growth in winter, especially on duplex soils.
Management of weeds, disease and nitrogen nutrition are ongoing challenges that limit yield potential.
