This subject provides students with an understanding of the importance of optimal use of nutrients and water in production to ensure maximum productivity whilst maintaining sustainability and avoiding off-site impact. The impact of tillage practices, rotational sequences, and livestock grazing on soil physical properties that influence soil fertility, infiltration and soil water availability will be assessed.

Topics include:

• evaluation of management strategies, cropping systems, and tillage systems that maximise infiltration and use stored soil water efficiently;

• developing skills in identifying major soil groups and land capability for specific land-use;

• providing a framework for evaluating soil: physical and chemical ­properties;

• developing an understanding of sustainable crop and integrated crop-livestock production systems that sustain soil and water quality without impacting adversely in the environment;

• evaluation of soil water and crop properties based on climatic parameters and meteorological conditions;

• developing awareness of the impact on soil and water nutrient levels as a result of intensive agricultural practices;

• the influence of intensive agriculture and horticulture on soil water and atmospheric conditions with examples of strategies to deal with these issues;

• issues associated with allocation of water between agricultural, environmental, urban industrial and recreational uses;

• developing knowledge of farm water supply systems for both stock and domestic use and irrigation in terms of both quality and quantity;

• water reclamation and re-use;

• methods of nutrient application including fertigation, broadcasting, row, deep placement and site specific will be discussed; and

• efficient and economic application of nutrients including the preparation of nutrient budgets and performance monitoring.

• 2 hour Exam 45%
• 2 x Assignments at 30% and 25%
