MODULE CONTENT
SOIL
Soil is the Material in the top layer of the surface of the earth in which plants can grow.
TYPES OF SOIL
Soil is divided into three part namely:
- Sandy soil;
- Clay soil;
- Loamy soil.
SANDY SOIL
Sandy soil is a loose material made up of tiny particles. These tiny particles consists of grains of rock (clay or mud). Sandy soil is not good for growing crops because it does not contain decayed animal and plants materials that should enrich the soil.
CLAY SOIL
Clay soil is a very fine-grained, smooth soil that can be moulded when wet (moist) and hard when the water in it dries up.
LOAMY SOIL
Loamy soil is a rich soil consisting of a mixture of sand and clay and decaying organic materials (dead plants and animals). It is the best soil for crops growing and can hold enough water.
Characteristics of Types of Soil
CHARACTERISTICS OF SANDY SOIL
- It does not contain many nutrient.
- It contains loose material of tiny particles
- Growth of crops is very poor.
- It can’t not hold water.
- It is rough when touched with hand.
CHARACTERISTICS OF CLAY SOIL
- It is a very fine-grained soil.
- It is smooth
- It can be used for mounding when wet.
- It is hard when the water in it dries up.
- Growths of crops is poor on it.
- It can hold water.
- It has small and closely packed particles.
- It can hold a lot of nutrients.
- It does not allow air and water through it.
CHARACTERISTICS OF LOAMY SOIL
- It is
a rich soil. - It contains
mixture of sand and clay. - It is the best soil for crops growing.
- It can hold enough water
- It is rich with nutrients
- It is rich with minerals.
COMPONENT OF SOIL
Soil is made up of the following components:
- Mineral matters or inorganic matters (45%)
- Organic matter (5%)
- Soil water (25%)
- Soil air (25%)
- Living organisms (insignificance)
