Vermicomposting: Process and its Benefits to Environment


Vermicomposting is noticeably the most preferred method of composting in the recent years. This is an easy process to get rid of the organic waste and to turn it into something useful. The major benefit of it is that it can be done on both large and small scale production. It is an eco-friendly approach for recycling organic waste into valuable bio-fertilizers. In simple words, vermicomposting is recycling of organic waste by using red wigglers, earthworms, white worms, whose excreta helps in the process of fertilization. The process of vermicomposting takes 22-23 days, depending on the density of waste and earthworm maturity.

The Process

It is a controlled degradation of organic waste by using worms. Micro-organisms, bacteria, earthworms participate in the vermicomposting process. The process of vermicomposting starts with the process of vermiculture (process of breeding of earthworms in a controlled condition). The bins used for vermicomposting are available in the market; some people also use old plastic containers available at home. These bins need to have holes for ventilation. Required amounts of yard waste and kitchen waste is stored in the bin. The bin is kept moist but not very wet. The bin is then filled with worms coupled with organic waste.

Benefits of Vermicomposting

  • Richer Soil

The earthworms leave the soil 10-15% richer with the essential plant nutrients of potassium, nitrogen, phosphorus etc., which leads to enhancement of the soil properties.

  • Helps in Growth of Plants

It is a preferred method used by farmers as it gives similar results as that of synthetic fertilizers and is suitable for the ecosystem as well.

  • Water Retention

In vermicomposting, the water is held at an organic level; therefore it tends to evaporate slowly and helps in water retention.

  • Good Substitute for Synthetic Fertilizer

Research has proven that crops fertilized with organic vermi fertilizer, give better performance than synthetic and inorganic fertilizers.
