Irrigation: Scheduling

Scheduling irrigation is about planning when and how much water to apply to a crop to achieve crop production or a particular quality. The principles of scheduling water apply to all crops, however the critical timing, methods and techniques can vary with the crop. 

This book is about

• the ways in which specific crops respond to stress and the effects of the timing and degree of stress and the growth stage of the crop 
• evapotranspiration (ET) and  crop water use to schedule irrigations
• developing an irrigation schedule
• terms used to describe the amount of water available to a crop
• soil moisture probes and where to locate them
• water quality issues to consider.
