Regarding soil, which of the following statements is true?a)A-zone of ...
The correct answer is a) A-zone of horizon of soil contains maximum humus.
In soil science, the term "horizon" refers to a layer within the soil profile. Soil profiles are made up of different horizons, each with its own characteristics and properties. The horizons of soil are typically designated by letters, with the topmost horizon being the A horizon, followed by the B horizon, the C horizon, and so on.
The A horizon, also known as the topsoil, is the topmost layer of soil and is typically rich in organic matter, such as humus. The B horizon, also known as the subsoil, is the layer of soil beneath the A horizon and is typically lower in organic matter. The C horizon is the layer of soil beneath the B horizon and is typically made up of largely decomposed rock and mineral particles. The D horizon is the layer of soil beneath the C horizon and is typically made up of bedrock.
Therefore, the A-zone of horizon of soil contains the maximum amount of humus.

A-zone of horizon of soil contains maximum humus
- The A-zone of the soil horizon is the topmost layer and is also known as the topsoil. It is the layer in which most of the plant roots are found.
- Humus is the organic matter that is formed by the decomposition of plant and animal materials. It is rich in nutrients and helps in retaining moisture in the soil.
- The A-zone of the soil horizon contains the maximum amount of humus. This is because it is the layer where most of the organic matter accumulates due to the decomposition of plant and animal residues.
- The humus in the A-zone of the soil horizon provides important benefits to the soil and plants. It improves the soil structure by binding soil particles together, making it easier for roots to penetrate and access nutrients and water.
- Humus also enhances the soil's ability to retain moisture, reducing water runoff and erosion. It acts as a reservoir of nutrients, releasing them slowly over time and preventing them from being washed away by heavy rains.
- Additionally, humus contributes to the dark brown or black color of the topsoil, which is often associated with fertile and productive soils.
- The A-zone of the soil horizon is crucial for plant growth as it provides a favorable environment for root development and nutrient uptake.
- It is important to protect and maintain the A-zone of the soil horizon by practicing sustainable agriculture and avoiding practices that can lead to soil degradation, such as excessive tilling or overuse of chemical fertilizers.
- By preserving the A-zone and its high humus content, we can ensure healthy and productive soils that support sustainable agriculture and provide essential resources for life on Earth.
