Soil Sieve Analysis

1.0      Introduction

Sieve analysis is an analytical technique used to determine the particle size distribution of the coarse and fine aggregates. The technique involves the layering of sieves with different grades of sieve opening sizes. The size distribution is critical crucial to the way the material performs in use and sieve analysis can be performed on any type of non-organic or organic granular materials including sands, crushed rock, clays, granite, feldspars, coal, soil, a wide range pf manufactured powders, grain and seeds then down minimum size depending on exact method. The amount is determined by largest size of aggregate is placed upon the top of a sieves and shaken by mechanical means for a period of the time. The top sieve has the largest screen openings and the screen opening sizes decreases with each sieve down to the bottom sieve which has smallest opening size screen for the type of material specified. Sieve analysis is important for analyzing materials because particle size distribution can affect a wide range of properties such as the strength of concrete, the solubility of a mixture, surface area properties and even their taste.

6.0      Discussion

Sieve analysis test helps to determine the particle size distribution of the coarse and fine aggregates. The calculated by the combination of several separate elements of the rocks is known as aggregates. Meanwhile, a sieve analysis can be performed on any either non-organic or organic granular materials including sands, crushed rock, clays, granite, feldspars, coal, soil, a wide range of manufactured powders, grain and seeds, down to a minimum size depending on the exact method. In this experiment, there are five types of dry soils that will be used for the sieve analysis which are Mangrove soil, FSSA soil, Lake of Residental College E, Sandy soil and Mountain soil. According to British Soil Classification System, the soils are classified according to different sizes which are further divided into course, medium and fine sub-groups.
From the graph above, it shows that Lake of Residental College E have almost same pattern as Mangrove soil while FSSA soil have almost same pattern as Mountain soil. Each of the soils have different type of percent passing through 0.063 mm. It is clearly that the finest soil of percentage is sandy soil with percentage of 92.257. Only a small percentage with 14.187 % of FSSA soil that can pass through the finest mesh sieve.
From the previous results, FSSA soil contains 0.20 cm of sand (3.08%) and 6.30 cm of silt (96.9%) and 0% of clay from the soil jar test. According to the soil texture triangle, it can be said that the FSSA soil is a silt soil. According to the theory, silt particles measure between 0.05 and 0.002 mm, suppose be the finest one. However, the type of FSSA soil that was determined through sieve analysis cannot be supported by the results of soil texture analysis and jar test analysis where both test have shown that the FSSA soil is a silt soil whereas the sieve analysis show it was the least soil in the percentage of finer.
This is because it can be shown that the soil with the highest percentage finer would be soil samples from silty clay loam. However, through the sieve analysis test sandy soil recorded the finest soil in the finest sieve opening mesh size as the percentage of finer soils that passed through the 63 microns sieve mesh was the highest (92.257%), followed by Lake of Residental College E soil (23.479%), mangrove soil (19.705%) and mountain soil (16.252%). This can be said that, as the sizes of the mesh sieves decreases, only finer particles such as clay and silt which the size ranges are smaller than sand would be able to pass through the sieves. So, it can be said that our sandy soil may the finest seamless sand which is the finest among the all types of soil (Haseeb Jamal, 2005).
Thus, method of using sieve analysis to calculate the mass and percentage of retained soil sometimes may not really accurate because there will be some particles that stuck in the opening of sieves and hardly to be removed as well as some of the soil particles may finer that the sieve opening mesh size. Furthermore, the results can also be affected by spilling of some particles contents during the separating of tightly fit the sieves from the nest after shaking. Therefore, to prevent and ensure the minimal loss of soil during the experiment, the difference between combined mass of all retained soil and pre-sieve soil can be compared. The larger the differences, the more soil is loss during the experiment which indicates inaccuracy in the result.

7.0      Conclusion

In conclusion, sandy soil recorded as the highest passing percentage (92.257%) which means the most the finest size particles pass through the sieve analysis. Then followed by lake of Residential College E soil (23.479%), mangrove soil (19.705%) and mountain soil (16.252%). For FSSA soil, recorded as the lowest passing percentage among these five soils which is 14.187%.

Soil Nutrient Analysis

1.0      Introduction

Plant growth and development largely depend on the combination and concentration of mineral nutrients available in soil. Plants often face significant challenges in obtaining an adequate supply of these nutrients to meet the demands of basic cellular processes due to their relatively immobility. A deficiency of any one of them may result in decreased plant productivity and fertility. Symptoms of nutrients deficiency may include stunted growth, death of plants tissue or yellowing of the leaves caused by reduced by a reduced production of chlorophyll, a pigment needed for photosynthesis.
Nutrient deficiency can have a significant impact on agriculture, resulting in reduced crop yield or reduced plant quality. Nutrients deficiency can also lead to reduced overall biodiversity since plants serve as the producers that support most food webs.
Changes in the climate and atmosphere can have serious effects on plants, including changes in the availability of certain nutrients. In a world of continual global climate change, it is very important to understand the strategies that plants have evolved to allow them to cope with some of these obstacles.
Two classes of nutrients are considered essential for plant which are macronutrients and micronutrients. Macronutrients are building blocks of crucial cellular components like proteins and nucleic. They required in large quantities. Nitrogen, phosphorus, magnesium and potassium are some of the most important macronutrients.
Micronutrients including iron, zinc, manganese and copper are required in very small amount. Micronutrients also often required as cofactor for enzymes. Mineral nutrients are usually obtained from the soil through plants roots, but many factors can affect the efficiency of nutrient acquisition. The chemistry and composition of certain soils can make it harder for the plants to absorb nutrients. The nutrients may not be available in certain soils, or may be present in forms that the plants cannot use. Soil properties like water content, pH and compaction may exacerbate these problems.
Plants are known to show different responses to different specific nutrients deficiencies and the responses can vary between species.

6.0      Discussion

Soil is a major source of nutrients needed by plants for growth. Plants need at least 17 nutrients. These include the macronutrients nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg) and sulphur (S) and the micronutrients chlorine (Cl), boron (B), iron (Fe), manganese (Mn), copper (Cu), zinc (Zn), nickel (Ni) and molybdenum (Mo). These are generally obtained from the soil. Crop production is often limited by low phytoavailability of essential mineral elements or the presence of excessive concentrations of potentially toxic mineral elements. The macronutrient are needed in large amount whereas the micronutrient are needed in small amount.
Nitrogen is a key element in plant growth. It is found in all plant cells, in plant proteins and hormones, and in chlorophyll. Atmospheric nitrogen is a source of soil nitrogen. Some plants such as legumes fix atmospheric nitrogen in their roots; otherwise fertiliser factories use nitrogen from the air to make ammonium sulphate, ammonium nitrate and urea. When applied to soil, nitrogen is converted to mineral form, nitrate, so that plants can take it up. Soils high in organic matter such as chocolate soils are generally higher in nitrogen than podzolic soils. Nitrate is easily leached out of soil by heavy rain, resulting in soil acidification.
Phosphorus (P) is important in cell division, root development, flowering and fruiting. Potassium (K) increases vigour and disease resistance of plants, helps form and move starches, sugars and oils in plants, and can improve fruit quality. On the other hand, sulphur is a structural component of some amino acids (including cysteine and methionine) and vitamins, and is essential for chloroplast growth and function; it is found in the iron-sulphur complexes of the electron transport chains in photosynthesis. It is needed for N2 fixation by legumes, and the conversion of nitrate into amino acids and then into protein. It is also responsible for many flavours and odours compounds in plants such as the aroma of onions and cabbage.
To determine the nutrient content, 680 Sulphate reagent was used to determine the amount of sulphate (sulphur) content in the soil , 490 P React PV-phosphorus was used to determine the amount of phosphorus content and 355 N, Nitrate HRPP was used to determine the nitrate (nitrogen) content. Firstly, the mangrove soil sulphate content is >3.5!, the nitrate content is 3.6 and the phosphorus content is 0.38 whereas for the mountain soil, the sulphate content is 1, the nitrate content is 2.8 and the phosphorus content is 0.19. For the soil from the lake of Residential College E , it has the highest amount of sulphate content compared to the rest which is 33, the nitrate content is over the detection limit which is also known as over the detection range and the phosphorus content is 0.51. Next, FSSA soil has got the most phosphorus content in its soil which is 0.90, the sulphate content is 18 and the nitrate content is 3.93. Lastly, the sandy soil has the highest content of nitrate which is 4.1, the sulphate content is 11 and the phosphorus content is 0.3.
Nitrogen deficiency most often results in stunted growth, slow growth, and chlorosis. Nitrogen deficient plants will also exhibit a purple appearance on the stems, petioles and underside of leaves from an accumulation of anthocyanin pigments. Besides that, phosphorus deficiency in plants is characterized by an intense green coloration or reddening in leaves due to lack of chlorophyll. If the plant is experiencing high phosphorus deficiencies the leaves may become denatured and show signs of death. Occasionally the leaves may appear purple from an accumulation of anthocyanin because phosphorus is a mobile nutrient, older leaves will show the first signs of deficiency. In plants, sulphur cannot be mobilized from older leaves for new growth, so deficiency symptoms are seen in the youngest tissues first. Symptoms of deficiency include yellowing of leaves and stunted growth. The lowest content for nitrate, sulphate and phosphorus is the soil from mountain. This explains no growth in the soil.

7.0        Conclusion

In conclusion, identification of macronutrient was conclude in Table 5.1. From that table, soil sample of lake of Residential College E recorded the highest macronutrient than other soil sample. So this is suitable for jagung pandan growth. Nutrient is very important for jagung pandan growth. Based on our observation, the leaf of jagung pandan is yellowish and purplish in colour. This indicates our jagung pandan is lack of phosphorus. But we cannot add on any fertilisers because we want to measure the origin nutrient inside each of our sample soil.
