Aims:

Identify profitable long term management of subsoil compaction for deep sandy soil at Binnu.

Crop type: Wheat 1 trial Soil Type Soil Compaction Soil amelioration Type
Binnu, WA Yellow deep sand
Research organisatons
Funding source

Aims:

To demonstrate more efficient deep ripping of a dry compact sandy soil and to assess any benefits of improved rain infiltration and crop yield.

Crop type: Wheat 1 trial Soil amelioration Application
east Buntine, ACT Sand over gravel
Research organisatons

Aims:

To provide an overview and improve understanding of the range of tillage implements available to growers to incorporate lime, their respective costs and benefits and to assess novel options.

Crop type: No crop specified 1 trial Soil amelioration Type
Dandaragan, WA
Source Data Unavailable
Research organisaton
Funding source

Aims:

To test the effect of very deep ripping to 500mm with shallow leading tines and incorporation of limesand on a very deeply compacted acid sand plain soil.

Crop type: Wheat 1 trial Fertiliser Rate Soil Preparation Soil amelioration Type
West Wubin, WA Sandy loam
Research organisaton
Funding source

Aims:

  • To test if the ‘window’ is broadened due to seed coating.
  • To test the effect on yield due to timing of ‘haircut’.

Crop type: Wheat 1 trial Herbicide Type Herbicide Timing Inoculant Application
East Dalwallinu, WA Sandy loam
Research organisaton
Funding source
NEAR Project

Aims:

To evaluate a range of seeding modifications or additions with the aim of improving crop establishment and yield on water repellent sandplain soil.

Crop type: Wheat 1 trial Soil amelioration
Badgingarra, WA Pale deep sand
Source Data Unavailable

Aims:

To evaluate banded wetting agent (SACOA ‘Irrigator’) for crop establishment and yield on non-wetting soils in the West Midlands.

Badgingarra, WA Warradarge, WA
Source Data Unavailable
Research organisatons
Funding source

Aims:

To assess what clay rich subsoil application rates are required for overcoming soil water repellence and how this interacts with method of incorporation.

Crop type: Wheat 4 trials Soil amelioration
Badgingarra, WA Balla, WA Binnu, WA Bolgart, WA Non-wetting sand

Aims:

Test benefits of ribbon sowing to improve yield of very wide rows in a dry season when sowing onto deep moisture.

Crop type: Wheat 1 trial Sowing Method Sowing Row spacing
Tardun, WA Sandy loam
Research organisaton

Aims:

To provide better guidelines on safer methods of sowing wheat on shallow soil in the low rainfall zone; especially in terms of row spacing seeding rate, variety, depth of soil and soil type.

Crop type: Wheat 1 trial Sowing Rate Sowing Row spacing
Pindar, WA Shallow red sandy clay loam
Research organisatons

Aims:

Evaluate benefits and penalties of cropping traffic on deep ripping.

Crop type: Wheat 1 trial Soil Compaction Soil Preparation Soil amelioration Application
Balla, WA Sandy duplex
Research organisatons
Funding source

Aims:

To evaluate benefits and penalties of cropping traffic on deep ripping.

Crop type: Wheat 1 trial Soil Compaction Soil Preparation Soil amelioration Application
Buntine, WA Sand over gravel
Research organisatons
Funding source

Aims:

To quantify the benefits of very wide rows for wheat quality and yield.

Crop type: Wheat 1 trial Sowing Row spacing
Pindar, WA Red loamy duplex
Research organisatons
Funding source

Aims:

To quantify the benefits pre-furrowing after pasture in a low rainfall area. Prefurrowing runs a point through dry soil to help rainfall entry.

Crop type: Wheat 1 trial Soil Type Sowing Method
Pindar, WA Various
Research organisaton

Aims:

To quantify the benefits of Tramline Farming in a low rainfall area.

Crop type: Wheat 1 trial Soil Compaction
East Wubin, WA Sandy duplex
Research organisatons

Aims:

To develop systems to protect grain quality and yield in a low rainfall area. Trying wider rows to conserve moisture instead of fallow.
