What does arid soil mean?
Arid Soil range from red to brown in color.They are generally sandy in texture and saline in nature. In some areas the salt content is very high and common salt is obtained by evaporating the water.Due to the dry climate,high temp.,evaporation is faster and the soil lacks humus and moisture. The lower horizons of the soil are occupied by kankar because of the increasing calcium content downwards . The kankar layer formation in the bottom horizons restrict the infiltration of water.After proper irrigation these soils become cultivable as has been in the case of western Rajasthan(INDIA).
What is seeping downward through the horizons dissolves and carries minerals into lower horizons by the process of?
Leaching is the process in which water seeping downward through the soil dissolves and carries minerals from the upper horizons into lower horizons. This movement of minerals can impact the soil fertility and nutrient availability in different layers of the soil profile.
A vertical section through all of the soil horizons?
A vertical section through all of the soil horizons is called a soil profile. It shows the different layers of soil, or horizons, from the surface down to the bedrock. These horizons are classified based on their physical and chemical properties, helping to understand the soil composition and characteristics.
What is the name of the process by which water carries materials from the upper horizons down on the lower levels?
The process you are referring to is called leaching. Leaching occurs when water transports minerals, nutrients, and other materials from the upper soil horizons down to the lower levels, which can affect soil fertility and the composition of different soil layers.
What do the horizons of soil make up?
The horizons of soil are typically made up of distinct layers known as O, A, E, B, C, and R horizons. These layers vary in composition and characteristics, such as organic matter presence, mineral content, and soil structure. The arrangement of these horizons helps to categorize and understand different soil types and their properties.

soil horizons determine the age of the soil

Which soil horizons are most prone to erosion?
A and O horizons
What are the differences between illuviation and elluviation?
Eluviation is the movement of the particles (such as minerals and organic matter) into lower soil horizons. Then Illuviation is the accumulation of those particles in the lower soil horizons.
What is the process in which water carries materials from the upper horizons down to the lower levels?
leaching
What is difference between old soil and young soil?
Old soil is more weathered and mature, with well-developed soil horizons and a higher concentration of nutrients. In contrast, young soil is less weathered, often has less distinct soil horizons, and may have lower nutrient levels. Old soil typically has better drainage and a higher capacity for supporting plant growth compared to young soil.
Are layers of soil called soil horizons?
Yes, layers of soil are called soil horizons. Soil horizons are distinct layers within the soil profile that have unique characteristics based on factors such as composition, color, texture, and organic matter content. These horizons are designated by letters (O, A, E, B, C, R) to indicate their position and properties within the soil profile.
