A three-year research project was conducted to encompass four studies where EM was
evaluated. These were the effects of EM on (1) Eliminating foul odor in poultry and pig farms,
(2) The weight gain of broilers, (3) The growth and yield of some vegetables and (4) Plants and
animals in terms of pathogenicity.
The application of EM technology in swine was evaluated after one year of study. Evaluation
was done on urine and faeces, pigpens, drain canals and septic tanks. Initial results showed
that foul odor in pigpens was greatly reduced by EM application. Using the hedonic scale,
67% of the evaluators rated the treated test sites as odorless, 23 % said that these were
slightly odorous, and 10% evaluated as moderately odorous. In poultry, the effects of EM as a
foul odor eliminator after one growing cycle of broilers was not very favourable. With the
same scale used in swine, 73 % of the evaluators rated moderately odorous, 20% rated slightly
odorous, and 7% rated strongly odorous.
In vegetables, the mean yield responses of test crop fertilized with sludge and effluent coming
from pigpens with and without EM application were similar. As to pathogenicity, no distinct
disease or pest, problems were observed in the test crops and animals regardless of treatments.
