What is Irrigation Water Requirement Calculations about?

This document provides two examples of calculating irrigation requirements for crops. The first example calculates that a crop requiring 12 mm of daily water consumption on a field with a 70 cm root zone, 28% field capacity and 13% wilting point would need irrigation every 9 days. The second example calculates that a crop with a 100 cm root zone, 22% field capacity, 12% wilting point, 25 mm/day consumption, and 50% irrigation efficiency would require irrigation with 15 cm of water every 6 days.
