what is the role of earthworm in soil preparation
Answers
Answer:
Earthworms maintain the physico-chemical properties of the soil by converting biodegradable materials and organic wastes into nutrient-rich products, emerging from their burrows to deposit the fecal matter (vermicast) on the surface. Earthworms stimulate microbial activity, mix and aggregate the soil, soil water content, and water holding capacity. The mutual action of earthworms and microbes brings faster decomposition as the earthworm’s condition, aerate, fragment, and enhance the surface area of the organic matter for microbial action. They also increase litter decomposition, soil organic matter dynamics, nutrient cycles, promote plant growth, and reduce some soil-borne diseases.
Answer:
Earthworms (EWs) are a major component of soil fauna communities in most ecosystems and comprise a large proportion of macrofauna biomass. Their activity is beneficial because it can enhance soil nutrient cycling through the rapid incorporation of detritus into mineral soils.
