ABSTRACT:
A method and mass for the drainage, irrigation and lightening of soils is constituted by hollow elements dispersed in soil so as to define capillary or semi-capillary passages. The elements are bulked up so that they can rest in an irregular fashion one relative to the others by providing in between them spaces of variable shapes and dimensions thereby to supply drainage, irrigation, lightening and enrichment of soils.
