Production & postharvest

The Department of Primary Industries and Regional Development contributes to the productivity, profitability and sustainability of plant-based agriculture. From broad scale dryland cropping systems to intensive irrigated production, we work with industry and business to address challenges in plant production through research and development, knowledge transfer and government policy settings.

  • 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.
