Every pots are labelled accordingly and filled approximately 5 litres of soil from different locations. Soils collected include soils from Faculty of Science and Natural Resources's Lake (FSSA Lake), Kampung E's Lake, FSSA's garden, Pusat Penataran Ilmu dan Bahasa (PPIB) and construction site soil respectively. A small portion of each soils is used to conduct pH test, soil texture as well as to determine its' dry mass. Each pot is given the same amount of seeds (20) and buried well. Our group decided to place the pots at the open area so they are expose and receive the maximum amount of sunlight as well as rainwater. All the group members take turns to water the pots with the same amount of tap water throughout the week. All the paddy plants are being examined and the results are recorded.
Here's our observation after 1 week:
- POT A (FSSA's Lake)
Soil pH (pH strips) : 5
Soil pH (pH meter) : 4.79
Seedlings observed : 3/20 [15%]
Highest seedling height : 4 cm
Average seedlings' height : 3.2 cm
- POT B (Kampung E's Lake)
Soil pH (pH strips) : 5
Soil pH (pH meter) : 5.38
Seedlings observed : 14/20 [70%]
Highest seedling height : 10.5 cm
Average seedings' height : 8.6 cm
- POT C (PPIB)
Soil pH (pH strips) : 5
Soil pH (pH meter) : 5.78
Seedlings observed : 18/20 [90%]
Highest seedling height : 8.5 cm
Average seedings' height : 7.3 cm
- POT D (FSSA's garden)
Soil pH (pH strips) : 5
Soil pH (pH meter) : 5.5
Seedlings observed : 19/20 [95%]
Highest seedling height : 12 cm
Average seedings' height : 9.8 cm
- POT E (Construction site)
Soil pH (pH strips) : 4
Soil pH (pH meter) : 4.57
Seedlings observed : 2/20 [10%]
Highest seedling height : 5 cm
Average seedings' height : 3.5 cm
Since all the soil were taken inside of UMS, I think it will be interesting if this group can map it on the UMS map, so the group can identify which part of UMS have what type of soil texture.

Include soil texture type.
Show jar test picture and textural triangulation diagram,calculation ect.
Assigned this task to Viannie.
After the plants are two weeks old, about Next Friday (12th May 2017), carefully dug out 5 whole seedlings from each pot.
Measure the whole plant length, root length only and shoot length only.
Measure the plant weight.
Air dry the plant.
After the plant are completely dried out, measure the plant weight.
