Which part of soil has organic materials incorporated with the mineral matter, nutrients and water?

Horizon A

The correct answer is Option (3)- Horizon A

The part of soil that has organic materials incorporated with mineral matter, nutrients, and water is called Horizon A.

Explanation:

Soil is typically organized into layers known as soil horizons, each with distinct characteristics. The topmost layer is called Horizon A, also known as the topsoil. This layer is rich in organic matter, minerals, nutrients, and microorganisms, making it the most fertile and productive layer for plant growth.

Horizon A is crucial for supporting plant life as it contains decomposed organic materials, which contribute to soil fertility and provide essential nutrients for plant growth. It is in this layer that roots of plants obtain the necessary water, minerals, and nutrients for their development.
