This Learning Activity Sheet is written and designed to help you understand more about the physical characteristics of the soil. It will guide you to master the lesson on how characteristics of each type of soil differ from each other. Soil is formed over long periods of time. It can take up to 1000 years to form just an inch of soil. Soil is made up of four things: rock fragments, dead and living things ,water and air.
There are various types of soil that undergo diverse environmental pressures. Soil is mainly classified by its texture, proportions and different forms of organic and mineral compositions.

COMPARING THE DIFFERENT TYPES OF SOIL
I. Learning Skills:
A. MELC: Compare and contrast the characteristics of different types of soil.
B. Objective:
1. Compare and contrast the characteristics of different types of soil.
II. Introductory Concept
This Learning Activity Sheet is written and designed to help you understand more
about the physical characteristics of the soil. It will guide you to master the lesson on how
characteristics of each type of soil differ from each other. Soil is formed over long periods
of time. It can take up to 1000 years to form just an inch of soil. Soil is made up of four
things: rock fragments, dead and living things ,water and air.
There are various types of soil that undergo diverse environmental pressures. Soil is
mainly classified by its texture, proportions and different forms of organic and mineral
compositions.
Let us take a look at the pictures.
Observe how the two types of soil differ from one another based on their physical
appearances (color, texture, particles, ability to absorb water, etc.)
Sandy soil loose granular materials consist of small particles of weathered rock. It is
one of the poorest types of soil for growing plants because it has very low nutrients and
poor in holding water, which makes it hard for the plant’s roots to absorb water. This type
of soil is very good for the drainage system.

3. .
Clay soil are tightly packed together with each other with very little or no airspace. This
soil has very good water storage qualities and making hard for moisture and air to
penetrate it. It is very sticky to the touch when wet, but smooth when dried. Clay is the
densest and heaviest types of soil which do not drains well or provides space for plant
roots to flourish.
Here is another set of picture. Observe and tell how each type of soil differ from
one another.
Loam soil has the ability to retain moisture and nutrients hence, it is more suitable
for farming. This soil is also referred to as an agricultural soil as it includes an equilibrium
of all three types of soil materials being sandy, clay, and silt and it also happens to have
humus. Apart from these, it also has higher calcium and pH levels because of
its inorganic origins.
Peat soil is high in organic matter and retains a large amount of moisture. This
type of soil is very rarely found in a garden and often imported into a garden to provide
an optimum soil based for planting.
Let’s have another type of soil.
Chalk soil is can be either light or heavy but always highly alkaline due to the
calcium carbonate or lime within its structure.
Silt soil made up of rock and other mineral particles which are smaller than sand
and larger than clay. It is the smooth and quite fine quality of the soil that holds water
better than sand. Silt is easily transported by moving currents and it is mainly found near
the river, lake, and other water bodies.
4. Study the table below. Are different types of soil differing in characteristics?
As you can see on the table the different types of soil have their own
characteristics meaning they have their own ability to sustain the life of living things.
They have different characteristics in terms of color, sizes, texture.
