Managing soils

Soil productivity is largely determined by its ability to provide water and nutrients to plants along with the way the soil constraints are being managed by growers. In many instances a particular soil will be constrained by more than one physical or chemical characteristic. In many cases, there are practical and profitable management options to reduce the effects of a constraint, leading to improved yields and profitability. Recognising soil constraints and their potential impact on agricultural systems is difficult, but very important. The department can provide the technical information needed for growers to understand the condition and properties of their soils, and develop management strategies to increase productivity and profitability and improve soil condition.

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

  • Healthy soils support the exchange of energy and nutrients, which sustains plant and animal life as well as the production and decomposition of organic matter.

  • These pages have been produced as an online user manual for iLime, outlining specific features of the app and how to use them.

  • 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.
