Abstract
We construct a series of blowups of a singular foliation by applying to the universal Lie -algebroid of a singular foliation the so-called Nash modification. For , we recover a blowup introduced Sinan Sert\"oz, and for , we recover a notion due to Omar Mohsen. One of the important features is that any singular foliation becomes a Debord foliation (= projective singular foliation) after one blowup. Examples are also given.

Comments
The title has been changed. The introduction has been extended. A new section on the smoothness of the Nash blowup has been added. The main results have been clarified. These main results are taken from Chapter 7 of my PhD thesis
