Information of insects that live in the soil and how does it makes it more fertile?

Question

it my homework

Answer 1

in addition to earthworms, redworms, millipedes, and centipedes, there are a number of microbes that aid in decomposition. Plant roots need air and water in addition to soil, so the tunnels the insects make help to provide the aeration and prevent compaction of the soil, which holds in too much moisture and causes root rot and related problems. Having a well aerated soil also allows for roots to go deeper in to the soil, creating a more erosion resistant plant.

In addition, the leftovers of worm feedings (worm castings, or, more specifically, worm f***s) is an excellent way to allow the nitrogen in organic matter to be in a form the plants can absorb easily through the roots. Many insects also live in the soil, especially centipedes, that feed on harmful insect pests that may harm your plants.  

Answer 2

there are lot of insects that live in the soil. They are earthworms,

millipedes,centipedes,snails etc. Earthworms they move

wthin the soil and allow proper passage for nitrogen to flow and

cause proper decomposition of materials making  rich  manure. thus it makes soil fertile.

Answer 3

Insects (as well as other macro-organisms, like earthworms) and micro-organisms, such as bacteria and fungi, that live in the soil are detritovores – that is, they feed on decaying plant and animal material.

This enhances the friability of the soil – making clay soil more porous adding necessary drainage and sandy soils more water retentive. This helps the spacing of particulate matter and the distribution of air and water – both of which are needed for healthy plant roots.

The byproduct of the soil organisms consumption is encapsulated fecal matter rich in nutrients that are released slowly into the soil – making soil more fertile and more or less neutral on the pH scale. An excellent environment for plants to grow, become more disease resistant and more productive.

Since soils rich in macro and micro organisms have a fairly neutral pH, the nutrients such as nitrogen, phosphate, potash, magnesium, zinc, iron, copper and other minerals do not get “locked-up”, as would happen in excessively acid or alkaline soil but are made available to the plants where they are needed.

Therefore, soil rich with life is rich with plant nutrition.

Some beneficial insects that live in soil are:

Sow or Pill Bugs (Woodlice)

Springtails

Mites

Fungus gnats

Soldier Fly Larvae  

Centipedes

Millipedes

Ants

and many more.

One common mistake made by gardeners is their concentration on ‘feeding the plants’ when in reality, they should be ‘feeding the soil’, to keep its living organisms alive and thriving.

You can find out a bit more by doing a search for ‘compost and its benefits’.
