Plant nutrition

Department of Primary Industries and Regional Development conducts and supports research into the agronomic requirements of a range of crops to provide information on crop nutrition to ensure optimum yields and quality. Plants require a number of nutrients to successfully grow and produce a crop. Western Australia's weather conditions can result in poor soil fertility and limited water supply which restrict a plants ability to uptake and use nutrients.

  • Deficient plants are smaller with yellow leaves and fewer tillers

    Nitrogen deficiency is the most common nutrient deficiency in wheat especially during cold, wet conditions and in well-drained soils in high rainfall areas.

  • Dark leaves with necrosis moving down from the tip of the oldest leaf

    Nearly all soils in Western Australia are phosphorus deficient in their natural state but the continual use of phosphorus fertiliser means acute deficiency in broadacre crops is rare, with the exce

  • Plants with fewer tillers and pale older leaves

    Nitrogen deficiency is the most common nutrient deficiency in barley especially during cold, wet conditions and in sandy soils in high rainfall areas.

     

  • Phosphorus deficient seedling

    Nearly all soils in Western Australia are phosphorus deficient but continual use of phosphorus fertiliser means acute deficiency in broadacre crops is rare, with the exception of Darling Range grav

  • 3Phase is a fertiliser program for growing lettuce, celery, cabbage and broccoli on sandy soils under irrigation.

  • The life of the celery crop is considered in three phases — establishment, rapid growth and maturation — and each phase has specific fertiliser requirements.

  • Hollow heart is an internal disorder where a 'lens' or 'star'-shaped cavity forms in the potato tuber.

  • The life of the broccoli crop is considered in three phases — establishment, rapid growth and maturation — and each phase has specific fertiliser requirements.

  • Phosphorus fertiliser application to potato crops should aim to maximise profits and also minimise the overuse of phosphorus to reduce environmental impacts and health risks.

  • Cauliflower and broccoli crops generally require multiple harvests to remove all marketable curds or heads. By improving the uniformity of plant maturation, crops can be harvested in a single pass.
