DIFFERENCE BETWEEN CLAYEY AND SANDY SOIL

CLAYEY SOIL SANDY SOIL
1. Very small air spaces between particles. 1. Larger air spaces between particles.
2. Water does not drain well. 2. Water drains well.
3. The soil remains wet. 3. Thr soil dries out easily.
4. Water can ride to a high level by capillarity 4. Water cannot rise to a high level by capillarity.

PROPERTIES OF SOIL

1.SOIL TEXTURE
It is the relative proportions of gravels, sand, silt and clay fractions in a given sample of soil.
The texture of any soil sample can be determined by using the feel of the soil rubbed between the fingers. For example, Sandy soil has rough or gritty feel, silt has a slippery feel, clayey soil has a smooth and sticky feel and loamy soil is in between Sandy and clayey soil.

IMPORTANCE OF SOIL TEXTURE
1. It helps the farmer to determine the type of crops to grow.
2. It has direct effect on the soil structure.

2.SOIL STRUCTURE
It describes how the soil particles are arranged or packed into groups or aggregates. Soil can be loosely or tightly packed.

IMPORTANCE OF SOIL STRUCTURE.
1. It reduces the rate of soil erosion.
2. It ensures good drainage system.
3. It promotes free movement of air in the soil.
4. It has the ability of retaining water for plant use.
5. It makes soil preparation easier

3.WATER HOLDING CAPACITY
It is the proportion of water a soil holds or retains.

4.SOIL AIR
It is the proportion of air in a soil.

5.SOIL POROSITY OR PERMEABILITY
This describes how easily water passes through the soil or the drainage ability of the soil. Soil can be well drained, moderately drained or poorly drained.

6.CAPILLARITY
It refers tohow water rise in the soil.
