This unit provides students with an understanding of the relevant industry systems within which the Australian grains industry operates. Topics include Quality Assurance (QA) systems within the grains industry, occupational health and safety principles, human resource management on-farm, socio-economics of grain production, grain processing and products, marketing and finance, risk management, and information systems for grain production. Students will be required to attend the equivalent of a 3-day intensive school to cover practical aspects of the unit. GRNS503 is based on the undergraduate unit GRNS303 with additional load consisting of extra questions on assignments and examinations and candidates for GRNS503 will be expected to show a greater level of understanding of the unit material than that required for GRNS303.
