• B. earthworm's casting mixed with soil
• C. casting alone
• D. dead earthworms mixed with soil.

Answer 1

The Correct Option is B

Vermicompost is a heterogeneous mixture of decomposing vegetable or food waste, bedding materials and vermicast. Vermicast, also called worm casting, worm humus or worm manure is the end product of the breakdown of the organic matter by earthworm. These castings have been shown to contain reduced levels of contaminants and a higher saturation of nutrient than do organic materials before composting. Vermicompost containing water soluble nuterients is an . excellent nutrient rich organic fertilizer which is a better alternative to chemical fertilizers as it does not affect soil pH and maintains soil fertility for years without affecting the food quality.
