Why earthworm is called as farmer’s friend?
Advertisements
उत्तर
Earthworms traverse agricultural lands and pastures. They consume the organic debris in the soil. They also facilitate the breakdown of organic materials. The loosening of soil from their actions promotes healthy root growth in crops. Their excreta enrich the soil by serving as fertilisers. All these facts render the earthworm a beneficial ally to farmers.
