N2  - Six different compost samples were evaluated. Marjoram compost was selected as the more humified one. Results of investigating isolation and purification procedures suggested milder methods to obtain good yield of humic acid with minimum structural alterations. Structural features studies of compost humic acid compared to more humified ones(i.e.Leonardite) and a synthetically prepared humic-like substance using a variety of wet-chemical and  spectroscopic methods, exhibit noticeable similarity and revealed that they are close to soil humic acids with slightly less aromaticity, molecular weight and functional groups content. With respect to biological activities studies they inhibited in vitro, mycelial growth of 5 from 8 phytopathogenic fungi tested
