Resumo
Using the method of Briggs and Shantz, several types of soils of the State of São Paulo were studied respecting their wilting points. The results obtained are given in the Table I, and show us that we cannot use as wilting point twice the value of the hygroscopicity as given by Camargo and Vageler for the soils of the State of São Paulo.
