Dancing Butterfly Pea Week 4 Report

Week 4 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. We continue to cover the pot with a box and bring the plant to a non windy place whenever played the music.

Sieve analysis test

We conduct sieve analysis test which commonly known as gradation test. From this we can determine the distribution of aggregates particles by size. Sieve analysis test helps to determine the particle size distribution of the coarse and fine aggregates. The soil that had been dried outside the laboratory for 2 weeks has been used for sieve analysis test. We had use 5 types of sieve opening mesh size as recorded in table below.  The all lumps are broken using mortar and pestle into small particle before they are passed through the sieves. The soil was distributed in the top sieve and sieved the soil for 15 minutes with the speed of 40. The results of sieve analysis are generally expressed in terms of the percentage of the total weight of soil that passed through different sieves.

Sieve No	Sieve opening mesh size	Mass of soil retained on each sieve	Percent of mass retained on each sieve(Rn)	Cumulative percent retained	Percent finer 100-∑Rn
1	2mm	0.26	0.08	0.08	99.92
2	1mm	44.46	13.54	13.62	86.38
3	212µm	178.93	54.49	68.11	31.89
4	125µm	62.27	18.96	87.07	12.93
5	63µm	29.05	8.85	95.92	4.08
6	Pan	13.40	4.08	100	0
Total	-	328.37	100	100	-

  

 Sieve analysis is to determine the size of particles present in the soil, the result of the total dry weight is expressed in a percentage form. Based on the table, the particles that left in the first and the second sieve plate are the remaining coarse particles while in the third until sixth are the fine particles. Most of the fine particles of soil was retained in 212µm sieve plate then followed by 125µm sieve plates, 1mm sieve plate, 63µm sieve plate and pan. For the coarse particles, majority of them were retained in 1mm compared to 2mm sieve plate. The soil retained in 2mm and 1mm were known as coarse sand while the 212µm, 125µm and 63µm known as fine sand while the soil retained in pan is silt because it is lower than 63µm .There is no clay particles retained in the soil in the sieve plate. From this we can conclude that our soil has more sand compared to silt and clay. So that it is a loamy soil as a same result we obtain by soil triangular texture experiment.
