Module 2, “Soil and Nutrition: Crops", begins in unit 2.1 with an in-depth analysis of soils' water storage properties and their role in the retention and supply of nutrients to plants.

Unit 2.2  investigates the soil, paddock, crop and other factors that need to influence your nutrient decisions. 

Units 2.3 through 2.6 focus on the the role of different nutrients in crop production, answering questions such as:

• What are macro and micro nutrients required by plants? 

• What is the specific role of each nutrient in crop production?

• How can you manipulate nutrient availability and correct deficiencies?

• What are the nutrition 'hot-spots' that will provide the best feedback on nutritional deficiencies?

The last three units provide an overview of soil tests for nutrients, salinity and disease,(2.7) plant tests such as near infra red reflectance (2.8) and a chart for checking your expected production yields against crop type and rainfall.
