Effetto del digestato sulla struttura del suolo

The aim of this work is to analyze the effect of the digestate on the soil, and mostly on its structure. Here is given a general description of the digestate, at the production level, by viewing its forms and quantities and, quantitatively, by analyzing the biochemical properties reported into the tables. Moreover is described the separation of digestate's solid and liquid states considering the differences between them from the biochemical point of view and the consequences on soil structure. Eventually is described the effect of digestate on soil structure by examining several articles about tests which have been carried out in the field and in the laboratory as well; among these articles one in particular, studyng the dimension and the stability of the aggregates and the vitality of earthworms, is deepened. In conclusion is examined on the whole if digestate is a good organic improver.
