SPECIMEN A (SANDY SOIL)
- It contains gravel coarse sand fine sand
and limited amount of silt.

Characteristics of specimen A
1. it is grey and brownish in
colour.
2. its particles are large.
3. it has lower water retention capacity
4. it is not pliable or plastic so it can not
form structure.
5. it has large pore spaces and therefore are wild aerated

Economic Importance Of Specimen A
1. easy to work on or plough upon.
2. easily washed away or leached
3. prevents waters lodging
4. easily heat up
5. well aerated
6. has low PH value hence likely acidic
7. support growth of water

SPECIMEN B (LOAMY SOIL)
- It contains fair balance of clay
silt and sand particles.

Characteristics Of Specimen B
1. it is dark brown or black in colour
2. it is not as coarse as sand nor as smooth as clay.
3. it has moderate speed pore space
4. it contains organic matters or residue
5. the rate of water percolation
is moderate

Economics Importance Of Speciment B
1. Moderate water absorbing and holding capacity
2. it contains organic matter which is source of plant nutrients when
decomposed
3. easy to work or plough upon
4. does not easily loose its nutrients through leaching
5. well aerated for root respiration and development.
6. best soil for crop cultivation example maize rice cassava
okro tomato and millet

SPECIMEN C (CLAY SOIL)
The particles are predominated by clay consisting of
about 60%.

Characteris Of Specimen C
1. it contains small fine poudry compact particles.
2. it is smooth and velvet
3. the pore space hence not well aerated
4. has low water retention.
5. grey or brownish in colour
6. friable or plastic or easy to mould.

Economic Importance Of Specimen C
1. difficult to work on or plough
2. poorly aerated
3. easily lodged by water.
4. not easily leached
5. not easily heated
6. supports growth

Difference Between Specimen A And C
1.
- SPECIMEN A has large particles
or coarsed Texture
- SPECIMEN C has small particles or fine Texture

2.
- SPECIMEN A is well aerated.
- SPECIMEN C is poorly aerated

3.
- SPECIMEN A is easy to plough
- SPECIMEN C Is difficult to plough

4.
- SPECIMEN A Forms no structure
- SPECIMEN Forms aggregate or lumps

5.
- SPECIMEN A is a Warmer Soil
- SPECIMEN C is a Cooler Soil

6.
- SPECIMEN A has poor water retention.
- SPECIMEN C has water retention

SPECIMEN D (PEBBLE OR SANDBSTONE)
It is a sedimentary rock formed by settling of sediments

Settling Of Sediments
The sediment are deposited in
layers by agents
like flowing water wind and Ice

Characteristics Of Specimen D
1. It Appears in layers
2. It has coarse texture
3. Presence Of Irregular fracture
4. Loosed Binding particles
5. Soft Easily Breaked When Slight force is
applied.

SPECIMEN E (GRANITE)
- It is an igneous rock formed by molten magma. (SOLIDIFICATION) from beneath the earth crust.
- It is the oldest known rock

Characteristics Of Specimen E
1. shiny in appearance
2. Light Dark in Colour.
3. Coarsely crystalline in appearance
4. Has firmed binding particles
5. Extremely hard Required a greater
force to break

SPECIMEN F (MARBLE)
- It is a metamorphic rock formed from igneous and sedimentary rock which as a result of
subjection to Intensive heat
Pressure hence
change it's former state by process of metamorphism, Chalk and Lime stone are
changed to marble

Characteristics Of Specimen F
1. Hard and do not break easily.
2. Shiny in appearance
3. Multi Coloured
4. Granular Texture
5. Crystalline Shape

SPECIMEN G [LITMUS PAPER (BLUE AND RED)]
It is a common indicator used
to determine
the acidity or alkalinenity of soil (Soil PH).

Characteristics Of Specimen G
1. Blue litmus paper turns red in acid
2. Red litmus paper turns red alkali
3. Litmus paper turns purple when neutral

SPECIMEN H [DILUTE HYDROCHLORIC ACID (HCL)]
It is an inorganic acid made of hydrogen and chlorin.
