Grains

The Department of Primary Industries and Regional Development has significant direct investment in grains research, development and extension capability and activities, research infrastructure and policy development.

The Western Australian grains industry is a major contributor to the agrifood sector and the Australian economy. WA produces on average 13 million tonnes of grains (cereals, oilseeds and pulses) each year. Grain exports generate more than $4 billion (five year average) for the WA economy each year – making it the largest agricultural sector in the state, and the fourth largest export industry overall after iron ore, oil and gas, and gold.

WA exports about 80% of its annual grain production to more than 50 countries worldwide. Indonesia is WA’s top wheat export market worth over $0.5 billion per year. WA is the world’s leading supplier of premium malting barley to China, the major supplier of wheat for the Japanese udon noodle market, and a major feed barley supplier to the Middle East.

In the 2014/15 season it is estimated the WA grains industry exported a total of $3.7 billion of cereals and $790 billion of pulse, pasture and oilseeds. The major contributors to these exports were wheat ($2.7 billion), barley ($905 million), canola ($710 million), oats ($83 million) and lupins ($77 million).

  • Acid soils cause significant losses in production and biomass, which restricts the ability to sequester carbon.

  • If you are deep-ripping, ploughing or spading to remove subsurface compaction or another constraint, it is a good idea to incorporate lime in the same operation.

  • Liming to recover an acidic soil to an appropriate pH can result in significant production benefits, however a response to liming indicates that previous production has been lost due to an acidic t

  • The rate of soil acidification due to agriculture can be reduced but not eliminated. Liming will always be needed to prevent the soil from becoming too acidic.

  • Soil acidification occurs naturally very slowly as soil is weathered, but this process is accelerated by productive agriculture.

  • A small decrease in soil pH represents a large increase in soil acidity.

  • 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.

  • Aluminium toxicity in the subsurface is the major problem associated with soil acidity in Western Australia.

  • Carbonate from calcium carbonate (or magnesium carbonate) neutralises acid in the soil.

  • In this section you will find detailed information on various case studies highlighting the long-term benefits of liming and different options used by farmers for incorporating lime.
