Abstract
In a theoretical approach the concept of soil available water for irrigated crops is critically evaluated. Laboratory-determined field capacity and permanent wilting point seem to give unsatisfactory estimates for the upper and lower limit of available water. Some new concepts of soil available water for crops are discussed. The need for a correct value of profile available water, that takes the interrelationship between soil, climate and crop into account is recognized.
