Abstract
A study on the effects of simulated rain at two different pH (3.0, 5.6 ) has been carried out on naturally sub-acidic (pH 5.2) soil samples f rom a Landriano farm (Milan, Italy). Biological activities (urease and ATP), microbiological groups (aerobic heterotrophic, free-living N-fi xing bacteria and Mycetes) and fungal microflora composition, have bee n monitored after 2, 4, and 6 months of treatment of the soil samples. The results showed that under these experimental conditions, acid tre atment affects significantly fungal microflora composition, not ATP co ntent and microbial counts. Urease activity increased with treatment a t pH 5.6.
