2014 AGRICULTURE MOST
EXPECTED WAEC SPECIMEN PRACTICAL SPECIMEN.

-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
SPECIMEN 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%.

CHARACTERISTICS 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 m*de of
hydrogen and chlorin
