The topsoil horizon (A horizon) is responsible for a soil's fertility as it contains the most organic matter and essential nutrients for plant growth. This layer is where plant roots are most active and where microbial activity is highest, contributing to the soil's overall fertility.

What horizon do tropical soils have?
Tropical soils typically have a shallow horizon profile due to high rates of weathering and leaching in the warm, humid climate. They often have distinct layers that are characterized by low fertility and organic matter content, as nutrients are quickly recycled and replenished through rapid decomposition.
What is the correct order of the different soil horizons?
The correct order of soil horizons, from top to bottom, is O horizon, A horizon, E horizon, B horizon, C horizon, and R horizon. It is important to note that not all soils have all these horizons, as they can vary depending on the specific conditions of the soil.
What are the differences between soil fertility and soil productivity?
The difference between soil fertility and soil productivity is that soil fertility involves the soils and fertilizing them per the types of plants, crops, and soils, being used. The soil productivity has to do with the drainage of the soils, the amounts and types of fertilizers, and the progress of the plants and crops due to fertilization.
In soils with distinct soil horizons the bottom zone is what?
The bottom zone in soils with distinct soil horizons is known as the C horizon. This layer is located below the B horizon and consists of partially weathered rocks and minerals. The C horizon is typically the least weathered and closest to the parent material.
In soils with distinct soil horizons the bottom zones are called what?
The bottom zones in soils with distinct soil horizons are called the C horizon. This horizon typically contains weathered parent material and has limited biological activity compared to the upper horizons.

In soils with distinct soil horizons the bottom zone is?
In soils with distinct soil horizons, the bottom zone is the bedrock denoted as R.
What are some vocabulary words for soil?
A Horizon, B Horizon, C horizon, bedrock, decomposers, earthworms, fertile soil, gardeners horizon, insect larvae, litter, moles, northern forest soils, organisms, plant roots, soil horizon, texture, weathered rock
What Soil responsible for high aggregate land?
Soils high in clay content are responsible for forming high aggregates, as they have the ability to bind particles together. Clay particles create spaces for air, water, and roots to move through, improving soil structure and fertility. Proper management of these soils, such as avoiding compaction and using organic matter, can enhance aggregate stability and overall soil health.
What are the Five soil horizons?
The five soil horizons are O horizon (organic matter), A horizon (topsoil), E horizon (eluviated or leached layer), B horizon (subsoil), and C horizon (parent material). These horizons collectively make up the soil profile and influence soil characteristics and fertility.
What type of soil does East Africa have?
East Africa has a diverse range of soil types, including volcanic soils, clay soils, sandy soils, and loamy soils. These soils vary in fertility and composition based on factors such as climate, topography, and geology. In general, the region's soils can support agriculture, but proper soil management practices are important for sustaining productivity.
What aspects of soils do pedologists study?
Pedologists study soil properties such as texture, structure, composition, fertility, and moisture content. They also examine soil formation processes, classification systems, and how soils support plant growth and other organisms. Additionally, pedologists study the relationship between soils and the environment, including their role in nutrient cycling, water filtration, and carbon storage.
