What is considered the minimum soil moisture level for effective irrigation management?

The minimum soil moisture level for effective irrigation management is recognized as 40% available soil moisture. This level is critical because it ensures that the soil retains enough moisture to support plant health while also preventing stress that can result from excessive drying. Maintaining moisture levels at or above this threshold helps optimize plant growth, encourages robust root development, and improves overall water use efficiency in irrigation practices.

If soil moisture falls below this level, plants can exhibit signs of stress, leading to reduced growth and yield. Additionally, understanding this level aids in planning irrigation schedules and determining when to supplement rainfall with irrigation, ensuring that crops receive adequate water without waste. This practice is crucial for sustainable agricultural management and helps conserve water resources while maximizing crop productivity.
