The study of soil

in agriculture use

”

Soil is a mixture of minerals, organic matter, gases, liquids and countless organisms that

together support life on Earth.

Problem StatementHow soil organic matter, soil

moisture, soil pH, water retention in different type of soil influence in the

field of agriculture?

1.To determine the percentage of

soil organic matter (SOM), soil moisture and water retention in different type of soil for benefit

in agriculture

Objective2.

To determine pH in different type of soil for benefit in

agriculture

Methodology

Loss on ignition

(LOI)

pH test by using universal indicator

Filtration

Loss On Ignition (LOI)

Put in oven to dried up

overnight(Determine soil

moisture)

Burn with bunsen burner for 45

minutes(Determine soil organic matter)

10g 6g 2g

pH test by using universal indicator

ResultsSandy Clay Silt Chalky

pH 8.0 7.0 6.5 9.0

Soil moisture 0.72% 56.23% 17.51% 9.61%

Soil Organic matter (SOM) 0.63% 25.11% 2.05% 0.22%

Water retention 35% 75% 25% 7.5%

Discussion

Sandy◉ pH:5.5◉ Low soil moisture, water

retention and SOM◉ Huge space between soil particle◉ Excellent drainage characteristic ◉ Suitable for: potatoes, tomato and

tobacco

Clay◉ pH:7.0 ◉ High soil moisture, water

retention and SOM◉ Smallest soil particles◉ Many small pore spaces◉ Little air passes through◉ Suitable for: Broccoli, cabbage

and Brussels sprouts

Silt◉ pH:6.5◉ Above average soil moisture,

water retention and SOM◉ Fine particles that can easily

compacted◉ Suitable for: carrots, potatoes,

tobacco, tomatoes

Chalky◉ pH:9.0 ◉ moderate soil moisture, water

retention and SOM◉ Consists large number of stones◉ Prone to dryness◉ Suitable for: Mushroom, yam,

okra

Clay is the BEST

among four soil samplexD

Soil with roughly equal proportions of sand, silt and clay.-Loam.
