Our soil textural triangle
The deposition of soil into three layers |
Calculation for the soil textural triangle |
The result showed the soil is loamy soil |
We weight the dried soil that we dried
outside of laboratory for a one week. The weight was reduced from 500grams to
402.29 grams so about 97.71 grams weighed is loss. Then we weighed about 20 grams of soil to conduct macronutrient
analysis which are Phosphate (PO43-), Sulphate (SO42-) and Nitrate (NO3-). We add
about 50ml of distilled water together with the soil sample and mix the
solution for 20 minutes by using magnetic stirrer. We left the mixture for 10
minutes. Then we filter the mixture by using 0.45 µm membrane filter
paper using vacuum pump. Then we Store in HDPE bottles for macronutrient
analysis using the HACH kit.
Here are the result of macronutrient
analysis

WEEK 2
DANCING BUTTERFLY PEA
We remained
water the plants 500ml twice a day in
the morning and in the evening. We played music each day after water the plants
twice a day for 20 minutes. The plants started to grow fastly.

Can the group post the music selection on the blog?
ReplyDeleteGroup discussion (insert for next report)
(1) Why was the soil weight reduce after 1 week?
(2) What is the optimum soil pH for butterfly pea growth?
What kind of soil does butterfly pea grows well?
(3) How does the amount of macronutrients in the current soil use for growing butterfly affect their growth?
Suggestion:
ReplyDeleteWhen the plants are listening to the music, can all the members surround it with a wall like a box. So you block wind.
Not to confuse either wind is making it moves or the plant itself.
Refrain from any conversation/noise near the plants when they listen to music.
ok madam we will block the plant from wind and avoid conversation whenever they listen to music
