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.
