Controlling the soil microflora to
enhance the predominance of beneficial
and Effective Microorganisms can help to
improve and maintain the soil chemical
and physical properties. The proper and
regular addition of organic amendments
are often an important part of any strategy
to exercise such control.
Previous efforts to significantly
change the indigenous microflora of a
soil by introducing single cultures of extrinsic microorganisms have largely been
unsuccessful. Even when a beneficial microorganism is isolated from a soil, cultured in the laboratory, and reinoculated
into the same soil at a very high population, it is immediately subject to competitive and antagonistic effects from the
indigenous soil microflora and its numbers soon decline. Thus, the probability
of shifting the "microbiological equilibhave a low Fusarium occupancy, and they
are often of the disease-suppressive type.
The production of gases from fields where
synthetic soils are present is minimal,
even for flooded rice.
