How do worms effect plants and soil?
Earthworms and plant growth have a special relationship; those wiggly worms make a big difference in how a tree blossoms or a flower blooms. The little bugs help the soil become more nutrient-rich by breaking down dead plant materials. This process creates humus, a natural fertilizer that plants use to grow taller and healthier.
How do worms help soil?
As well as keeping soil healthy, worms can help clean up contaminated land by enhancing ‘bioremediation’ – the process by which micro-organisms consume and break down environmental pollutants converting them to non-toxic molecules.
How do worms help clean up soil?
As well as keeping soil healthy, worms can help clean up contaminated land by enhancing ‘bioremediation’ – the process by which micro-organisms consume and break down environmental pollutants converting them to non-toxic molecules.
What do worms do when they eat?
When they eat, worms break down and recycle this organic matter within the soil which helps naturally fertilise the earth and ensure it’s packed with vital nutrients. The little mounds you sometimes see on top of the soil are called worm castings (essentially, worm poo!) and are the end product of this recycling process.
What is the function of burrowing and wriggling in soil?
Their wriggling and burrowing movements regulate the distribution of these micro-organisms in the soil.

How do earthworms move soil?
Charles Darwin calculated that earthworms can move large amounts of soil from the lower strata to the surface and also carry organic matter down into deeper soil layers. A large proportion of soil passes through the guts of earthworms, and they can turn over the top six inches (15 cm) of soil in ten to twenty years.
What Do Earthworms Do?
Earthworms dramatically alter soil structure, water movement, nutrient dynamics, and plant growth. They are not essential to all healthy soil systems, but their presence is usually an indicator of a healthy system. Earthworms perform several beneficial functions.
How do earthworms increase porosity?
Increase infiltration. Earthworms enhance porosity as they move through the soil. Some species make permanent burrows deep into the soil. These burrows can persist long after the inhabitant has died, and can be a major conduit for soil drainage, particularly under heavy rainfall.
What are deep burrowing earthworms?
Deep-burrowing species – Anecic species. These earthworms, which are typified by the “night crawler,” Lumbricus terrestris, inhabit more or less permanent burrow systems that may extend several meters into the soil. They feed mainly on surface litter that they pull into their burrows. They may leave plugs, organic matter, or cast (excreted soil and mineral particles) blocking the mouth of their burrows.
What are the casts on soil?
Casts at the soil surface are evidence that earthworms are shredding, mixing, and burying surface residue.
How many species of earthworms are there?
They are divided into 23 families, more than 700 genera, and more than 7,000 species. They range from an inch to two yards in length and are found seasonally at all depths in the soil. In terms of biomass and overall activity, earthworms dominate the world of soil invertebrates, including arthropods. Earthworms.
Which family of earthworms is most important in enhancing agricultural soil?
The family of earthworms that is most important in enhancing agricultural soil is Lumbricidae, which includes the genuses Lumbricus, Aporrectodea, and several others. Lumbricids originated in Europe and have been transported by human activities to many parts of the world. The United States has only one or two known native species of lumbricids. Others were brought to this country by settlers (probably in potted plants from Europe), and were distributed down the waterways.
Why Do Earthworms And Worms Live In Soil?
The reason why worms and earthworms live in the soil is that they feed on decaying animals and plants.
Why do worms like to be on top of the soil?
Worms and earthworms also love being on top of the surface because decaying animals and plants are mostly on the surface. This is why worms and earthworms love to be burrowed deep in the soil.
How Deep Do Earthworms Live?
Ideally, worms and earthworms live on the ground because of the moist soil. In a normal situation, worms and earthworms do not burrow so deep because the decaying organic matter is not below deep down the soil but on the surface.
Why do worms need to stay away from the sun?
They also need to stay away from the sun because the sun’s heat can dry them out and suffocate them. Worms and earthworms mostly live on soil, burrowed just underneath the surface. But some worms live underwater. There are thousands of worm species, and they are scattered all around the world.
What do worms eat?
These organic materials include leaves and branches. These worms and earthworms will eat these organic matters and turn them into nutrients. These nutrients will then go into the soil. Your plants and trees will eat these nutrients.
Why do worms need to be moist?
Worms and earthworms need to be moist all the time to breathe and absorb oxygen into their body. If the worm or earthworm will dry out or have dry skin, the worms and earthworms will eventually suffocate and die.
How do worms stay alive?
These worms will stay alive by digging their way deep down the soil to stay warm from all the ice. In typical weather, worms and earthworms will still burrow themselves on the ground but not deep enough. They will dig depending on their exposure to the sun.
Why are worms active in gardens?
Worms in gardens are most active when soil is moderately warm and moist. Their tunneling behavior accentuates the percolation of water into the soil. They also loosen soil so oxygen and aerobic bacteria can get into plant roots.
What are the functions of worms in gardens?
Worms in gardens also perform cultivation functions that increase soil porosity and allow oxygen to get into roots. Encourage earthworms in soil or even try worm composting to experience the life-giving effects of worm castings.

Characteristics
- Of all the members of the soil food web, earthworms need the least introduction. Most people become familiar with these soft, slimy, invertebrates at a young age. Earthworms are hermaphrodites, meaning that they exhibit both male and female characteristics.
Habitat
- Earthworms occur in most temperate soils and many tropical soils. They are divided into 23 families, more than 700 genera, and more than 7,000 species. They range from an inch to two yards in length and are found seasonally at all depths in the soil.
Diet
- In terms of biomass and overall activity, earthworms dominate the world of soil invertebrates, including arthropods.
Functions
- Stimulate microbial activity. Although earthworms derive their nutrition from microorganisms, many more microorganisms are present in their feces or casts than in the organic matter that they consume. As organic matter passes through their intestines, it is fragmented and inoculated with microorganisms. Increased microbial activity facilitates the cycling of nutrients from organic matt…
Causes
- Mix and aggregate soil. As they consume organic matter and mineral particles, earthworms excrete wastes in the form of casts, a type of soil aggregate. Charles Darwin calculated that earthworms can move large amounts of soil from the lower strata to the surface and also carry organic matter down into deeper soil layers. A large proportion of soil p...
Goals
- Provide channels for root growth. The channels made by deep-burrowing earthworms are lined with readily available nutrients and make it easier for roots to penetrate deep into the soil.
Ecology
- Different species of earthworms inhabit different parts of the soil and have distinct feeding strategies. They can be separated into three major ecological groups based on their feeding and burrowing habits. All three groups are common and important to soil structure.
Types
- Surface soil and litter species Epigeic species. These species live in or near surface plant litter. They are typically small and are adapted to the highly variable moisture and temperature conditions at the soil surface. The worms found in compost piles are epigeic and are unlikely to survive in the low organic matter environment of soil.
Species
- The family of earthworms that is most important in enhancing agricultural soil is Lumbricidae, which includes the genuses Lumbricus, Aporrectodea, and several others. Lumbricids originated in Europe and have been transported by human activities to many parts of the world. The United States has only one or two known native species of lumbricids. Others were brought to this coun…
Distribution
- Generally, lumbricids are much more common in the north and east than in the drier south and west of the United States. They tend to be more abundant in loam and clay loam and even in silty soil, than in sandy soil and heavy clay. Populations also build up in irrigated soil. Earthworm populations tend to increase with soil organic matter levels and decrease with soil disturbances, …
Benefits
- Earthworms improve water infiltration and water holding capacity because their shredding, mixing, and defecating enhances soil structure. In addition, burrows provide quick entry for water into and through soil. High infiltration rates help prevent pollution by minimizing runoff, erosion, and chemical transport to surface waters. Although there is much more to learn about how earthwor…
Criticism
- There is concern that burrows may increase the transport of pollutants, such as nitrates or pesticides, into groundwater. However, the movement of potential pollutants through soil is not a straightforward process and it is not clear when earthworm activity will or will not have a negative impact on groundwater quality.
