Soil Quality Lab Report Objectives
SoilQuality Lab Report
Theobjective of the experiment is to determine if the of soil has anoptimal condition for the growth of trees by testing for soilproperties such as lux, pH, moisture content, and the total amount ofworms.
Agricultureas a science relies much on the availability of scientific approachaimed at enhancing the production of a specific piece of land. Theavailability of science has made it possible for agriculturalists toestablish the optimal growth conditions required for different typesof plants besides the fundamental requirements which are moisture,oxygen, and warmth (Chesworth,2008).Soil quality has been proved to be an essential element in ensuringplants do well in a particular area. Soil quality can be analyzed inthree different approaches physical characteristics, chemicalcharacteristics and biological characteristics. Physicalcharacteristics of soil analyses the properties of soil such astexture and color. Chemical testing checks for the pH of the soil,Moisture content among other minerals such as magnesium, calcium,potassium, and sodium (Chesworth,2008).Biological tests analyze the availability of soil worms, surroundingplants like weeds, and crop pests. Soil analysis thus provides apreliminary report giving the odds of a plant surviving a particularsoil (Lichtfouse,2017).
Duringthe lab experiment, soil analysis was done to evaluate if trees cando well in a specific soil sample. The analysis such as Lux, pH,moisture content, and the total amount of worms was done on soil. Fora tree to optimally grow, it needs sufficient sunlight, sufficientwater, minerals and soil reaction such as pH, and temperature orlight intensity.
Thearea was sampled at three different points marked as area 1, area 2,and area 3. Soil samples from these three points were all dividedinto three 3 different beakers each for testing for the 3 differentsoil properties (Moisture content, pH, and total amount of worms).Lux on the other hand, was measured at the areas marked 1-3 since ithad to be measured at the exact point to establish light intensity.After the tests, the following results were derived.

Luxis an essential property in the success of trees growing in aparticular area since it shows that amount of light in the area.Sunlight is important in growth as it facilitates photosynthesiswhich provides food for plants. The lack of enough sunlight neededfor a tree to grow can be caused by other trees growing too tall inthe forest thereby forming a canopy which blocks enough light for theshorter and growing plants (Chesworth,2008).According to the experiment, the light intensity was found to be770Lux for all the three areas. Trees can thus do well in all thesethree areas since there is sufficient light which will avert stuntedgrowth for the trees. All the three areas provide optimal Luxcondition for tree growth.
SoilpH is also a critical parameter in the survival of tree since mosttrees do well in soil of pH ranging between 6 and 6.5. It is thusimportant to understand if the soil pH falls within recommendedlimits before the trees are planted. Plants will not do well if thepH of the soil is below the required minimum or above the requiredmaximum (Chesworth,2008).It is thus important that when trees are planted in soils that havethe right pH values. The three samples of soil had pH values of 7.19,7.28 and 6.1 for Area 1, Area 2, and Area 3 respectively. This thusshows that the pH value for area 3 will within recommended limits, itis the best location for planting trees. However, despite the factthat area 1and 2 had pH values slightly higher than the recommendedlimits, they are still favorable areas for planting trees since thedifference in pH is minimal.
Moisturecontent is also key for tree since they need water as a raw materialfor manufacturing its food through photosynthesis (Lichtfouse,2017).Moisture is key to any soil since most plants cannot do well in verydry soil. The three soil samples analyzed showed water content levelsto be at 24.6%, 25.5% and 45.8% for Area 1, Area 2, and Area 3respectively. The results showed that Area 3 had the highest watercontent as compared to Area 1 and 2. All the three areas can,however, support tree planting since the water content is goodenough.
Lastly,worms are essential to the healthy growth of trees since they are notonly a source of vital nutrients when they die but also aerate thesoil giving the root access to water and air. The total amount ofworms in three areas were tested by counting the number of wormsfound in the soil and also by the total weight of the worms(Lichtfouse,2017).According to the result, Area 3 was high in the number of worms ascompared to other areas. However, the three areas showed similarweight of worms. Thus, all the three areas have an optimal amount andweight of worms to support trees.
Thetype of soil in Area 1, Area 2, and Area 3 are all able to supportoptimal growth of plants. It can thus be concluded that theobjectives of the experiment were met since of the sampled areas cansupport optimal growth of trees. In the experiment, it was, however,assumed that there was a minimal human interruption in the forest andthere are also biodiversities. The soil quality is thus concluded tobe healthy.
