Test: Soil - JAMB MCQ

Sandy soil is characterized by large particles, which create larger pore spaces, allowing water to drain quickly. This type of soil is less able to retain water compared to other soil types.

Loamy soil is a mixture of sand, silt, and clay particles. It has a balanced texture that allows for good drainage while retaining adequate moisture and nutrients. It is considered ideal for agriculture.

Clayey soil is characterized by very fine particles, which pack closely together, creating small pore spaces. This type of soil retains water well but can lead to poor drainage and potential waterlogging.

Humus-rich soil refers to soil that contains a high amount of organic matter derived from the decomposition of plant and animal materials. It is typically dark in color and provides nutrients for plant growth.

Clayey soil has cohesive properties, allowing it to have good load-bearing capacity. It is less prone to erosion and can provide stable support for building structures.

Clayey soil has fine particles that create narrow capillary spaces, facilitating the upward movement of water. This property is useful for plant roots to access moisture.

Clayey soil has a low porosity due to its fine particles and compact structure. It has limited pore spaces, leading to poor drainage and potential waterlogging.

Loamy soil is highly suitable for gardening and horticulture purposes because it has a balanced texture, good drainage, and water-holding capacity. It provides an ideal environment for plant growth.

Sandy soil has large particles that do not bind well together, making it prone to erosion by wind and water. The loose structure of sandy soil allows it to be easily carried away.

Clayey soil is rich in nutrients but has poor drainage due to its compact structure. Proper management techniques such as adding organic matter and incorporating drainage systems can improve its drainage characteristics.
