Particle size distribution: Graphical representation

Pot A- PPIB's Parking Area: 

Based on the soil texture analysis that we have done on the first week through our PPIB soil jar test analysis and the calculation using soil texture triangulation. The texture that result from our jar test analysis is loamy fined sandy . Loamy fined sandy composed mostly of sand with the particle size is larger than 63 µm, silt with particle size larger than 2 µm, and a smaller amount of clay with particle size is larger than 2 µm.

As can be seen from the sieve result, there were many types of sand size. Particles that left on the first, second and third sieve plate is coarse sand while particle that left on the fourth sieve plate is  medium sand and particles left on fifth sieve plate is a fine sand. The last plate which is pan is the amount of particle that has size of smaller than 63 µm . That means the particle left on the pan is silt. For the clay, since clay particle is less than 2 µm, it is hard to say that our soil has clay particle. This is because the smaller opening mesh size is to big which is 63 µm. It may exist in our soil but , our group confirm that our soil texture is a loamy fined sand based on our result of jar test and soil triangular experiment.

Pot B-Fssa

Based on the soil texture analysis that we have done on the first week through our FSSA soil jar test analysis and the calculation using soil texture triangulation. The texture that result from our jar test analysis is sandy loam . Sandy loam composed mostly of sand with the particle size is larger than 63 µm, silt with particle size larger than 2 µm, and a smaller amount of clay with particle size is larger than 2 µm.

From the sieve result, there were many types of sand size. Particles that left on the first, second and third sieve plate is coarse sand while particle that left on the fourth sieve plate is  medium sand and particles left on fifth sieve plate is a fine sand. The last plate which is pan is the amount of particle that has size of smaller than 63 µm . That means the particle left on the pan is silt. For the clay, since clay particle is less than 2 µm, it is hard to say that our soil has clay particle. This is because the smaller opening mesh size is to big which is 63 µm. It may exist in small volume but our group confirm that our soil texture is a sandy loam based on our result of jar test and soil triangular experiment.

Pot C: Mengkabung

Based on the soil texture analysis that we have done on the first week through our Mengkabung soil jar test analysis and the calculation using soil texture triangulation. The texture that result from our jar test analysis is a clay loam.

Based on the table, the particle 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 125µm sieve plates followed by 63µm sieve plate, 212µm  and 1µm. For the coarse particles, majority of them were retained in 2mm compared to 1mm 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  

Pot D: Tepi Tasik FSSA

Based on the soil texture analysis that we have done on the first week through our Tepi Tasik FSSA soil jar test analysis and the calculation using soil texture triangulation. The texture that result from our jar test analysis is loam . Loam is soil composed mostly of sand (particle size > 63 µm), silt (particle size > 2 µm), and a smaller amount of clay (particle size < 2 µm). Its composition is about 40–40–20% concentration of sand-silt-clay, respectively.

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.

Pot E: Tepi Tasik FSSA 2

Based on the soil texture analysis that we have done on the first week through our Tepi Tasik 2 soil jar test analysis and the calculation using soil texture triangulation. The texture that result from our jar test analysis is sandy loam . Sandy loam composed mostly of sand with the particle size is larger than 63 µm, silt with particle size larger than 2 µm, and a smaller amount of clay with particle size is larger than 2 µm.

From the sieve result, there were many types of sand size. Particles that left on the first, second and third sieve plate is coarse sand while particle that left on the fourth sieve plate is  medium sand and particles left on fifth sieve plate is a fine sand. The last plate which is pan is the amount of particle that has size of smaller than 63 µm . That means the particle left on the pan is silt. For the clay, since clay particle is less than 2 µm, it is hard to say that our soil has clay particle. This is because the smaller opening mesh size is to big which is 63 µm. It may exist in small volume but our group confirm that our soil texture is a sandy loam based on our result of jar test and soil triangular experiment
