Answer 1

Answer:

here's your answer

Explanation:

Earthworm burrows increase soil porosity which increases the amount of air and water that get into the soil. Increased porosity also lowers bulk density and increases root development. Earthworm excrement or casts increase soil fertility because it contains nitrogen, phosphorus, potassium, and magnesium.Earthworms need the food and habitat provided by surface residue, and they eat the fungi that become more common in no-till soils. As earthworm populations increase, they pull more and more residue into their burrows, helping to mix organic matter into the soil, improving soil structure and water infiltration.Earthworms play a huge role in breaking down organic matter and fertilising soil, they simply do this through their constant need to eat and excrete, producing 'worm cast'. This worm cast is full of beneficial bacteria and nutrients which provides a healthy habitat for plants and other organisms.

Answer 2

Earthworms increase soil aeration, infiltration, structure, nutrient cycling, water movement, and plant growth.
