DISCUSSION
The result shows value of soil moisture content and pH value by using portable soil moisture sensor. Soil moisture is the amount of water contained in the soil. Based on the result, we can see that before watering the paddy plants all the type of soils are remain all same for the soil moisture value which is 1. However, after watering the plant for 4 hours all the reading had been increased dramatically. Parking lot soils has the highest increase in moisture content which is 6.7 while mangrove and in front A1 has the lowest moisture content (2.7). For field and ODEC soils, the moisture content also increase which are 6 and 4.5 respectively. This is due to size of the soil particles. The size of soil particles is an important part of making soil either good or not good at growing the plants. This is because the smaller the size of soil particles, more water can retains in the soils. Therefore, parking lot soils has more water content in the soil because of smaller in size of soil particles compared to the others soils.
Moreover, there is no big difference in the soil pH before and after watering the plant. The highest increase in its soil pH is field soil is 0.5 from 4.2 to 4.7. Next, mangrove and ODEC soils remain still with no increase or decrease in soil pH which is 0 respectively. For parking lot soil, this soil has decrease in the soil pH from 5.8 to 5.5. Also, same goes to in front A1 soils, it is has slightly decrease (0.2) which is from 5.2 to 5.0. Therefore, all type of the soils are in range soil pH <7 which is acidity soils.

Table 1 shows that the upland paddy plant average growth highest in soil of in front A1 compared to others soil. This shows that the nutrients contain in soil of in front A1 is more than others. So, it means that the plant intake more nutrients and grow better. For the longest length of root is the plant in ODEC soil. Where the root of plant represents the amount intake of water and nutrient by plant. As it has the longest root, plant in ODEC soil should be the bigger plant. But the inaccurate of this result may due to the process on dig out the plant. ODEC soil is the easiest to dig out the plant as the soil is soft. So from the other soil may have the inconvenience which break the root that stick tightly with soil. For the longest length of shoot is the plant in parking lot’s soil. Shoot of a plant including the stem until leaves where also can be used to determine the healthiness of a plant. Plant in soil of in front A1 also have the long length compare to the other 3 soils. This results shows that the plant in soil of in front A1 and parking lot is healthier. The length different between plant of these 2 soils not much.

Table 2 shows the wet weight which is origin from plant and the dry weight which after drying the plant. Upland paddy plant in soil of in front A1 has the greater wet weight compare to others. However, upland paddy plant in soil of parking lot has the greater dry weight. These shows that plant in soil of in front A1 have the most moisture content than plant in soil of parking lot. The different between the original weight and the dried weight of plant in soil of in front A1 is the most.
From the results, upland paddy plant in soil of in front A1 has the highest length and also greater wet weight. This shows that soil of in front A1 is suitable for paddy plant as the water intake and nutrients is good for the plant. Thus, the plant growing very healthy and big in size. Soil of parking lot also quite suitable for paddy plant as from the results shows is not much different with soil of in front a1. Only that the ability moisture content of the soil weaker than paddy as the paddy plant requires water to growth. However, results also shows that no plant growth in soil of mangrove.

1) Soil Texture INTRODUCTION Soil is a material composed of five ingredients — minerals, soil organic matter, living organisms, gas, and water (Needelman, 2013). Soil performs many essential functions in almost any ecosystems, like farm, forest, marsh and so on. Soil is a natural resource, an amazing substance. Earth is unique because there is dirt on Earth, Mars and Venus do not have soil. The texture and the distribution of mineral particles in the soil are the most important for the soil. Soil texture is an inherent soil quality property (Measuring Soil Texture in the Laboratory, 2018). The percentages of particles in these size classes is called soil texture (Needelman, 2013). Soil texture affects microbial activity by directly affecting water content and the temperature of soil (Chodak et al., 2010). The textural class is also important for soil aggregation and porosity. In addition, soil texture plays a key role in gas exchange (respiration of roots and microor

Second Lab Report : Sengkuang Lecturer: Mdm. Diana Demiyah Mohd Hamdan Group Members : 1.0  INTRODUCTION      Water holding capacity designates the ability of a soil to hold water. It is useful information for irrigation scheduling, crop selection, groundwater contamination considerations, estimating runoff and determining when plants will become stressed. Soil moisture available for plant growth makes up approximately 0.01 percent of the world's stored water. Soil texture and structure greatly influence water infiltration, permeability and water-holding capacity. Soil texture refers to the composition of the soil in terms of the proportion of small, medium and large particles (clay, silt, and sand, respectively) in a specific soil mass. For example, a coarse soil is sand or loamy sand, a medium soil is a loam, silt loam, or silt and a fine soil is a sandy clay, silt clay, or clay. Water holding capacity varies by soil texture.      Soil moisture

Title: Soil Colour and Soil Texture Analysis Lecturer: Dr. Diana Demiyah Mohd Hamdan Date of Submission: 24th March 2018 NAME MATRIC NUMBER SOW XIAO HUI BS17110464 KONG WAN LING BS17110429 AARON CHIN VUI CHANG BS17160670 NURUL NATASYAH BINTI KANAPIA@HANAFIAH BS17110546 NURFATIN SOFEA BINTI MOHD HELMI BS17110574 Soil Colour Analysis 1.0 Introduction The colour of the soil is usually the first thing people notice. Mostly this is just the topsoil but it does not reflect the entire soil. The topsoil is usually darker than lower layers (or horizons) because this is where organic matter accumulates. Soil colour is usually due to 3 main pigments: black—from organic matter, red—from iron and aluminium oxides and white—from silicates and salt. Colour can be a useful indicator of some of the general properties of a soil, as well as some of the chemical processes that are occu
