	Vegetable mould creates fertile soil. Earthworms prepare the ground for the growth of fibrous-rooted plants and many types of seedlings~~; they help~~ to expose and sift the vegetable mould. With vegetable mould, soil is in a state fitted to retain moisture and absorb soluble substances. [4] Nitrification is possible with vegetable mould in soil, as well. The constant movement by worms in soil allows for materials to be buried beneath accumulated castings of worms, and then brought to a decayed state. [5] All humic substances are able to chelate soil nutrients and act as a storehouse of ~~Nitrogen~~, ~~Phosphorus~~, ~~Sulphur~~ and ~~Zinc~~. Humic substances can also improve nutrient uptake, especially phosphorous, sulfur, and nitrogen. [6]		Vegetable mould creates fertile soil.

	Earthworms sift ~~the~~ finer soils from ~~the~~ coarser, mix the soil with mineral particles, and saturate it with intestinal secretion. Earthworm burrowing, casting, grazing, and dispersal change the soil's physico-chemical and biological status and could cause drastic shifts in the density, [[diversity]], structure and activity within the [[drilosphere]].

	Vegetable mould is the layer of dark colored, uniformly fine soil particles that cover the surface of land in moderately humid climates. This layer of mould, known as a form of soil [[humus]], can reach a depth of 40 cm or more in the soil profile. Earthworm secretions (or castings) primarily compose vegetable mould, and the layer is a few inches thick. Vegetable mould is located in the O Horizon of the [[Soil Horizons]].
