The entry requirement for this occupation is a bachelor degree or higher qualification. In some instances relevant experience is required in addition to the formal qualification.
- investigates soil fertility taking into account microbial populations, soil fauna, content of organic matter and presence of nitrogen, oxygen and other elements required for plant growth and productivity
- studies the physical and chemical properties of soils to determine the potential for plant growth, water absorption capacity, drainage characteristics, acidity, texture and degree of salinity
- develops soil management practices, and studies their effects on the long-term productivity of soil
- determines the mineralogy and structure of soil constituents to explain absorption processes
- investigates the mechanical properties of soils to improve tillage practices
- studies the influence of soil properties on the amount and chemical content of recharge to ground water tables
- investigates and advises on soil conservation problems and farming practices to reduce soil erosion and water quality deterioration
- advises on water quality and salinity problems, particularly those associated with irrigation
- may examine layering and drainage of soils used in foundations for roads, dams, buildings and other structures
