Abstract

In ecological investigations of interactions between plants and soil moisture, whether the aim is to determine fundamental plant-environment relationships or primarily to solve immediate plant production problems, the soil moisture content at permanent wilting, expressed as a percentage of the dry weight, is a basic determination. Although there is evidence that this soil moisture value may not represent the exact non-available moisture content of the soil (4, 8) it is generally agreed that it represents the limit of favorable plant growth conditions and will be considered here as non-available soil moisture.
