Adequate quantities of quality water for irrigating crops is one of the critical issues growers face. Vegetable growers are being given the tools to improve irrigation efficiency and maximise plant growth and profits by learning when to water and how much to apply so that they can maximise yields and profits. It also discusses how researchers at the Victorian Department of Primary Industries are finding that a range of different soil health practices have both environmental and economic benefits to growers. By measuring biological, physical, and chemical properties in soil, they are identifying which methods improve soil quality, while providing good yields and maximum profit.
