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.

  • Manganese deficiency is most often seen on well drained neutral or calcareous soils but heavy fertiliser usage can induce it in other soils, particularly after heavy applications of lime.

  • It is difficult to provide prescriptive guidelines for strawberry irrigation given the wide range of planting configurations and irrigation layouts.

    Oats are very susceptible to manganese (Mn) deficiency, which produces a condition called 'grey speck'.

  • Oat plants showing symptoms of acute phosphorous deficiency including necosis moving down from old leaf tip

    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

    Potassium is required for photosynthesis, transport of sugars, enzyme activation and controlling water balance within plant cells.
