Group Jicama Week 2

Week 2 lab (soil samples macronutrient analysis)

The soil that has been dried outside of the lab is measured. 

Type of soil: Soil near Tasik FSSA (sandy clay loam)

Weight of wet soil: 500g

Weight of dry soil: 470. 63g

Weight loss: 500g - 470.63g = 29.37g

Nutrient analysis testing with HACH DR2800 Spectrophotometer

Type of soil: Soil near Tasik FSSA (sandy clay loam)

An average weight is calculated from 3 readings.

Nitrate (NO₃-)

= (79.1 mg/L + 85.7 mg/L + 85.4 mg/L) /3

= 83.40 mg/L

Phosphate (PO₄^3-)

= (0.72 mg/L + 0.73 mg/L + 0.73 mg/L) /3

= 0.73 mg/L

Sulphate (SO₄^2-)

= (12.0 mg/L + 14.0 mg/L + 14.0 mg/L) /3

= 13.33 mg/L

Plants' progress:

This week, we have reduced the amount of watering to 250 ml per session for each pot, with two sessions per day. (morning and afternoon). All pots are watered everyday. 

Pot 1 ( Date: 6/5/2017), Saturday

Amount of watering: 250 ml per session

Germination rate: 8/12 X 100 = 66.67%

Average plant's height: 

=(9.5+ 8.9+ 10.1+6.2+2.0+7.2+7.3+1.0)cm /8

=6.5 cm

Pot 2 (Date: 6/5/2017), Saturday

Amount of watering: 250 ml per session

Germination rate: 7/12 X 100 = 58.33%

Average plant's height: 

=(8.2+ 5.1+ 2.8+2.6+2.5+1.0+1.0)cm /7

=3.3 cm

Pot 3(Date: 6/5/2017), Saturday

Amount of watering: 250 ml per session

Germination rate: 3/12 X 100 = 25%

Average plant's height: 

=(1.5+3.8+3.8)cm /3

=3.0 cm

Pot 4(Date: 6/5/2017), Saturday

Amount of watering: 250 ml per session

Germination rate: 12/12 X 100 = 100%

Average plant's height: 

=(11.5+11.0+8.0+8.1+14.0+13.0+10.0+10.5+2.3+

2.5 +4.0+7.0)cm / 12

=8.5 cm

Pot 5(Date: 6/5/2017), Saturday

Amount of watering: 250 ml per session

Germination rate: 10/12 X 100 = 83.33%

Average plant's height: 

=(1.0+3.0+1.0+3.0+6.5+7.0+7.0+3.0+5.0+8.5)cm /10

=4.5 cm
