How does organic material enter soil?
Answers
Bot
Organic material can enter soil through several natural processes, including:
1. Decomposition: When organic matter, such as leaves, grass, and dead animals, decompose, they break down into smaller pieces and mix with the soil.
2. Animal activity: When animals burrow in the soil, they bring organic matter to the surface, which mixes with the soil.
3. Plant roots: Plants take up nutrients from the soil, and as they die, the organic matter in their roots decomposes and mixes with the soil.
4. Weathering: Water, wind, and other natural forces break down rocks and minerals, releasing nutrients into the soil, which can support the growth of organic matter.
5. Biological activity: Microorganisms, such as bacteria, fungi, and earthworms, break down organic matter and help to incorporate it into the soil.
