What does humus primarily consist of?

  1. Unprocessed soil materials

  2. Organic matter that has decomposed

  3. Minerals and rocks

  4. Synthetic fertilizers

The correct answer is: Organic matter that has decomposed

Humus is primarily composed of organic matter that has decomposed. This material is the result of the breakdown of plant and animal material by microbes, leading to a rich, dark substance in the soil. Humus plays a crucial role in soil health as it improves soil structure, enhances water retention, and provides essential nutrients for plants. Its presence is vital for supporting microbial life and contributes to the overall fertility of the soil, making it more capable of sustaining agricultural practices and growing healthy crops. The complexity and stability of humus make it a fundamental component in sustainable agribusiness and farming strategies, as it contributes to long-term soil productivity.
