What is the role of earthworms and insects in soil?
Earthworms play a vital role in nitrogen mineralization through the release of metabolic products such as mucus, casts, and urine, which contain urea, uric acid, and dead tissue. Nitrogen mineralization can also be enhanced indirectly through the fragmentation of organic matter and alteration of the soil’s physical properties.
How do earthworms increase the fertility of soil?
Earthworm excrement or casts increase soil fertility because it contains nitrogen, phosphorus, potassium, and magnesium. How do earthworms improve soil fertility? Earthworms also mix soil layers and incorporate organic matter into the soil. This improves the fertility of the soil, as the organic matter is dispersed and the nutrients become available to bacteria, fungi and plants.
What is the importance of earthworms?
The importance of earthworms for soil structure. It was in 1881 that Charles Darwin published his influential book ‘The Formation of Vegetable Mould through the Action of Worms with Observations in their Habits.’. People must have been aware, probably since the dawn of agriculture, of the beneficial effects of earthworms on the soil, ...
How do earthworms affect soil?
That is, earthworms directly improve the structure of the soil and hence its stability. Of course, it has long been known that worms improve the aeration and drainage of soils through their burrows, but they also have a more fundamental effect. Through their activity they directly promote the aggregation or crumb structure of the soil.
How do sticky substances affect soil?
So these sticky substances glue the mineral particles together in the aggregates and , at the same time, in a kind of mutual relationship, the mineral particles protect the organic matter, to some extent, from microbial attack and thus preserve it for a longer time in the soil. However, microbial attack does continue, if only at a much-reduced rate, so eventually the aggregates are liable to break down, as the soil microorganisms consume the sticky substances that are holding them altogether. At the same time aggregates are continually being formed, as a result of various processes in the soil – physical, chemical and biological. It is the relative rates of these two contrary processes – aggregation and disaggregation (or breakdown) – that determine the future nature of the soil.
Why are aggregates important for plants?
It is crucial for plant growth that the individual mineral particles in the soil clump together into larger pieces called aggregates, which, because they are more irregular in size and shape than the individual mineral particles, have more spaces between them, through which air, water and plant roots can pass.
What would happen if there was no structure in the soil?
If the soil had no structure, there would be nothing holding the individual mineral particles in place and they could very easily be washed away by rain or blown away by wind. These aggregates make another important contribution to the soil properties, apart from leaving spaces between them and stabilising the soil.
How long does it take for the earthworm population to recover?
The earthworm population will recover in a few years if the soil is left undisturbed, but, if cultivation is repeated every year, as it often is, then the earthworm population will have no chance to recover and will remain well below the natural level. Darwin, C. 1881.
What do slugs need?
They need two things more than anything. First of all, they need dead plant material to feed on, so we have to supply that in the form of crop residues and mulches. Secondly, they need to be left alone to do their work. Disturbance of the soil is bad for them.
The worth of the worms
So worms are triply important – as well as aerating the soil and incorporating dead plant material into the soil organic matter, they also help to maintain or improve soil structure.

How do earthworms help the soil?
As the earthworms move around, they help loosen the soil and provide more aeration, making it easier for nutrients to reach the surface. The movement of the earthworms from one point to another gives the earth more nutrients. Hence, it helps to reduce erosion and flooding.
Why are earthworms important?
Earthworms are significant because they can help in the remediation of contaminated soil. The use of earthworms to restore ecosystems that got destroyed through mining has also been suggested as a viable option to support the ecosystem.
What do earthworms eat?
They provide an essential protein-rich food source for other significant species in the ecosystem like birds, hedgehogs, and frogs. This brings us to the question: what do earthworms eat to provide such nutrients to help the ecosystem? They can naturally survive on their own by feeding on fungi and bacteria. Earthworms accelerate the degradation of organic matter by increasing the surface area involved through the comminution.
What are the benefits of earthworms?
Beneficial effects of earthworms are due to increased nutrients, water availability, improved soil structure, stimulation of microorganisms, or the formation of microbes to enhance plant growth or possibly through the direct production of plant growth-promoting substances by the earthworms .
How do worms affect soil erosion?
This is to say, the presence of worms that have high percolation ability can decrease soil erosion by up to 50%. Endogeic-decompacting species in the tropics play a crucial role by increasing the soil and water infiltration porosity, which helps reduce run-off significantly.
Who discovered the role of earthworms in the ecosystem?
Charles Darwin was the first person who recognized how important the roles of the earthworms are in the ecosystem. He discovered it by using lime and ash to test the earthworms, and the result he got on how well the earthworms absorbed the substance was remarkable.
Is an earthworm a creepy crawly?
Studies have shown that earthworms are not just “creepy crawlies,” as most people refer to them.
Why are earthworms important?
Because of all of the important functions earthworms perform in our soils it is crucial to have a soil teaming with life. Earthworms do not like soil that is too acid, alkaline, dry, wet, hot or cold , their presence is a good indicator of soil conditions suitable for plant growth.Below is an outline of the way in which you can encourage earths in ...
How do earthworms help plants?
It’s within this process of mixing that disperses the organic matter throughout the soil and makes the nutrients held in it available to plants. In addition earthworms propagate microorganisms in their gut adding to the biological population in the soil. Earthworms when present improve the soil physical, chemical and biological properties ...
What are the microbial organisms that live in soil?
Microbes and earthworms play an important role in the soil ecosystem sometimes referred to as the soil food web. This soil food wed consists of both small and large organisms with the smallest being the microscopic bacteria and fungi that are attracted to the plant exudates and consume organic matter, nitrogen, and nutrients. These organisms hold the nutrients in their body, and when they die they become slow release fertilisers for the plants. They also are food for the second level of organisms that exist in the soil, such as nematodes and protozoa. These organisms are then fed upon by millipedes and earthworms and other organisms. The soil ecosystem has a huge amount of biodiversity. In addition, previous studies have documented earthworm movement toward microbial food sources which shows how crucial it is to promote healthy biological activity in your soil. EM can play in role in this, as a microbial inoculant consisting of bacteria, yeast and fungi that can deliver significant inputs of microbes to your soil. EM will also play a role in stimulating native soil microbes to produce a healthy functioning biological soil, which in turn encourages earthworm activity.
What are the most important organisms in soil?
Earthworms are one of the most important organisms in soils. Earthworms mix together different layers of soil and incorporate carbon in the form of organic matter into the soil. It’s within this process of mixing that disperses the organic matter throughout the soil and makes the nutrients held in it available to plants. In addition earthworms propagate microorganisms in their gut adding to the biological population in the soil. Earthworms when present improve the soil physical, chemical and biological properties and acts as soil conditioner. They do this is through: 1 Fragmentation 2 Aeration and soil aggregation 3 The breakdown of organic matter in soil 4 Release of plant available nutrients 5 Secretion of plant growth hormones 6 Performing their role in nitrogen fixation 7 Carbon dynamics 8 Microbial production 9 Phosphorous dynamics 10 Reducing compaction 11 Increasing water infiltration

Worms need oxygen to survive so a reasonably aerated soil is essential. This explains why worms aren’t present in anaerobic and heavily waterlogged soils .
What is the best way to keep soil moisture?
Groundcover such as pasture or stubble reduces moisture evaporation. Decaying organic matter (humus) holds moisture in the soil. In the heat of summer some earthworm species burrow deep into the soil and are inactive until soil moisture returns.
What do earthworms eat?
Earthworms feed on soil and dead or decaying plant matter, including straw , leaf litter and dead roots etc. They are the principal agents in mixing dead surface matter with the soil, making the carbon more accessible to decomposition by soil microbes. Examples of this include crop residues and stubble, green manure crops pasture residues.
