Radiometric measurements of a cotton canopy exposed to long term moisture stress are compared with those obtained using the technique of suddenly induced moisture stress. It is shown that the results obtained from both techniques are broadly similar. It is also demonstrated that the changes in reflectance in the near-infrared are closely related to changes in leaf hydrostatic tension. Since changes in leaf hydrostatic tension are used to trigger irrigation applications, this opens up the possibility of using field radiometry as a tool in irrigation water use planning.
