Decomposers: Rice Wash and Molasses

Here is another study conducted by our group – the Biological Science Major students during our Ecology course.


Decomposers are vital components of the nutrient cycle.  Without decomposers, nutrients would not cycle back into our environment and waste would accumulate at an alarming rate.  If decomposers did not exist, within a month the earth would be covered in a layer of dead flies almost twenty feet deep!  Thankfully, decomposers consume dead plant and animal matter, so the nutrients contained within them can be reused.  Likewise, if nutrients were not recycled in our environment they would not be available to other organisms.

Decomposers can be used as an organic foliar fertilizer. Spraying also allows plants to benefit from the pesticidal properties of the decomposer. Apart from inhibiting arthropod pests like aphids and spider mites, it also suppresses plant diseases (ex. Pythium) and plant parasitic nematodes (ex. root knot nematodes).

Decomposer is also an excellent plant growth promoter and soil amendment. According to soil scientists, using decomposer produces major growth differences between plants grown on soil and water and those grown on soil and decomposer. “The presence of plant growth regulators in the decomposers can influence plant growth significantly independent of nutrient availability.”

Vermiculture and Vermicomposting

About 2,350 years ago Aristotle has said, “Earthworms are intestines of the earth.” Only in the twentieth century has the truth in this statement been verified and found correct. He was ahead of our times by two and half of millennia. Darwin was another one to state: “No other creature has contributed to building of earth as earthworm.”

Vermiculture is basically the science of breeding and raising earthworms. It defines the thrilling potential for waste reduction, fertilizer production, as well as an assortment of possible uses for the future (Entre Pinoys, 2010).

Vermicomposting is the process of producing organic fertilizer or the vermicompost from bio-degradable materials with earthworms. Composting with worms avoids the needless disposal of vegetative food wastes and enjoys the benefits of high quality compost.

The earthworm is one of nature’s pinnacle “soil scientists.” Earthworms are liberated and cost effective farm relief. The worms are accountable for a variety of elements including turning common soil into superior quality. They break down organic matter and when they eat, they leave behind castings that are an exceptionally valuable type of fertilizer (, 2010).

This research paper would rationalize the methodologies as well as the laboratory findings undertaken by the Bachelor of Secondary Education (BSEd), Biological Science Major, Third Year Students of RMTU San Marcelino Campus on their innovative approach on Vermiculture and Vermicomposting.
