Humus is an effective fertilizer for the following reasons:
1. **It is rich in organic matter.** - Humus contains a variety of organic compounds that improve soil structure and fertility.
2. **It is abundant in inorganic nutrients.** - While primarily comprised of organic material, humus can also help hold and release essential nutrients in forms that plants can use.
The other options are not accurate:
- **It doesn’t need microorganisms to decompose matter.** - Humus is formed through the decomposition of organic matter, which does involve microorganisms.
- **It is dense and does not contain organic matter.** - This statement is incorrect as humus is specifically characterized by its high organic matter content.
So, the correct selections are the first two: "It is rich in organic matter" and "It is abundant in inorganic nutrients."
