            Disscussion

Based on MIT System of Soil Classification, the mass of soil retained in 2mm sieve simply belongs to gravel as their range of particle size between 2mm and 60mm. It shows high frictional resistance. Sand has a particle size ranging from 0.06mm to 2mm. It is grey in colour. It possesses  high strength in confined state and has considerable frictional resistance. Also, it has high permeability and low capillarity. Silt particle range in size from 0.02mm to 0.06mm. Silt have high capillarity and very low dry strength. Since particle size ranges in between that of clay and sand thus possessing properties of both sand and clay such as, it shows slight cohesion and also friction. The colour of silty soil is mostly brown. Clay is composed of very fine particles (less than 0.002 mm in size). They are flaky in shape, thus having considerable surface area. They also have high inter particle attraction and thus having sufficient cohesion. Other than that, they are susceptible to swelling and shrinkage, and possess low permeability. Commonly brown in colour.

Table 1 shows the the results from a sieve analysis performed on a sample that was measured to be 146.1627g. It can be seen that the third sieve (212µm) has the highest percent of mass retained (Rn) which is 25.8% while the lowest is the pan (below 63µm).

Figure 1 shows the sieve analysis based on the sieve size (mm) over the passing percentage (%). The graph shows an overall decreasing trend. In specific, it decreases gradually from 2mm sieve to 0.212mm sieve. After that it takes a sudden plunge all the way. It can be said that there were already not much soil left to pass, thus the sudden fluctuation.

   Discussion

   The table 2 shows the weight of soil wet, table 3 shows the weight of dry soil after two week and table 4 shows the moisture content of soil. The changing is very obvious after the soil dried up outside the laboratory. The moisture content ( also referred to as water content) is an indicator or an amount of water present in the soil.  By definition, moisture content is the ratio of the mass of water in a sample to the mass of solids in the sample. From the table 2 shows that bowl 1 has the highest weight of wet soil which is 179.725 g and bowl 2 shows the lowest weight of wet soil which is 88.411 g.

   For the weight of dry soil in the table 3 shows the highest weight of dry soil is bowl 1 which is 155.935 g and bowl 2 shows the lowest weight of dry soil which is 76.931 g. The weight of soil became decrease after have been dried outside the lab through the evaporation process that mostly come from the sunlight. The table 4 shows the highest moisture of content is bowl 4 which is 15.327 % and the lowest moisture of content is bowl 2 which is 12.985 %. In drying soils, very small changes in water content can lead to very large changes in water potential.

 Table 5: Macronutrients of soil

Reading	Macronutrients of soil (mg/L)
	Sulfate	Nitrate	Phosphate

3	12.00	5.50	4.40

   Discussion

   The table 5 shows the macronutrients of soil with three reading. The macronutrients that had been taking were sulfate, nitrate and phosphate. These macronutrients are the main macronutrients in the soil for growth of plants. Sulfate is a constituent of amino acids in plant proteins and involved in energy for producing processes in plants. Nitrate is the key element in plant growth. It is mostly found in all plant cells. Phosphate helps transfer energy from sunlight to plants, stimulates early root and for plant growth.

   Figure 2 shows the macronutrients and reading of the soil. From the figure above for the three reading of sulfate macronutrients show no change which is 12 mg/L. Nitrate shows increase of reading from reading 1 until reading 3. However, for the reading of phosphate shows decline from the reading 1 until reading 3. Overall, the result shows sulfate has the highest macronutrients in the soil and phosphate has the lowest macronutrients in the soil.
