The effect of micro-organisms on the effectiveness of soil conditioners

, : The effect of micro-organisms on the effectiveness of soil conditioners. Agricoltura Italiana 72(27 n.s.)(4): 272-276

In a laboratory experiment in which non-sterile soil and soil sterilized by propylene vapour was incubated for sixty days with nylon 6, 10, poly- alpha -Me-styrene, polybutadiene, urtal, polystyrene or polyvinyl- alpha -naphthalene, the favourable effect of the conditioners on the structure of an alluvial and a Pliocene clay soil decreased with time in sterile soil but not in non-sterile soil.
