Soil management

Crop production in Western Australia presents a variety of management problems arising directly from the inherent properties of the soils. Department of Agriculture and Food, Western Australia (DAFWA) conducts and supports research into managing the structure, waterholding capacity and fertility of these soils and can provide technical information to assist landholders make better management decisions.

    People unfamiliar with raised beds are often concerned with the proportion of land occupied by furrows.

    The use of no-till crop establishment practice is essential for farming raised beds. Cultivation is likely to degrade the bed and furrow construction.

    The machinery needed to crop raised beds requires only one additional, specialised implement—a bedformer, which also converts to a bed-renovator.

    Waterlogging occurs when rainfall exceeds the ability of the soil to conduct the excess moisture. Soil pore space becomes saturated with water, starving roots of oxygen and affecting plant growth.

    Drainage is usually the best way of reducing waterlogging. Other management options to reduce the impact of waterlogging include: choice of crop, seeding, fertiliser and weed control.

    The costs of installing a system of raised beds should be recovered through a cropping program.

    Confident identification of soil compaction to restrict crop or pasture growth uses diagnosis combining visual symptoms of plant, root and soil features.

    Surface and subsurface soils can be compacted. Livestock and light machinery often compact surface soil.
