Title: Enhancement animal manure compost value by using effective mircrobial.
Abstract: Intensive pig farming uses to generate excessive animal
manure under a confine space. This excessive animal
manure can be managed by composting process to utilize it as an organic fertilizer. Duration of composting process
can be shortening by using effective microbial, Effective
microbial (EM) are defined as group of beneficial
microorganisms that are claimed to enhance microbial
activity in compost and soil, which may increase their
nutrients value. In view of that a study on evaluation the
effective of EM composting process was conducted on pig
manure from an intensive pig farm. Two compost piles
were set up based on 2 different treatments; (I) Compost
without EM or as a control, (II) Compost with EM. The
ingredients (manure, sawdust, charcoal, limestone and
EM) were well mixed under shed on concrete flooring.
Each treatment was turned over weekly to allow aeration.
The samples of compost piles were collected every 5
subsequent day for their nutrients analysis, and in situ
parameters were measured daily. In terms of EM
efficiency, it was found that temperature and pH of
compost treated with EM were higher than the control
result. The result showed that compost with EM had
better nutrient values than compost without EM in terms
of nutrient contents. Total nitrogen content was increased
about 4 % and 7% gain for TI and TIl, respectively.
However, a decrease of P and K content about 16% and
8%, respectively found in Tl. A decrease result of Pabout
2.5% and no change of K content in TIL The C/N ratio
was decreased about 13.5% and 23% for TI and TIl, respectively.
