Two soil sampling points were selected within the study area: one located under Large trees and the open area where Strelitzia was planted.Measurement of soil moisture,measurement of Soil. Acidity,Alkalinity and Measuring Light Intensity . At each study site, soil samples were collected from two sampling points and placed on a plate. The structure was Analyzed using the CU Smart Lens,photographs of the soil samples were taken and compared with soil data. Texture (soil fixation) calibration plate. The soil structure was then documented.
Research on Environmental Science on Comparison of Soil Quality and Light Intensity in Areas Under Large Trees and Open Areas Planted with Strelitzia at Wichienmatu School, Trang Province. There are three objectives as follows: 1). to compare the soil quality in the area under the big trees and the open area planted with Strelitzia.2). to compare light intensity in areas under large trees and open areas planted with Strelitzia and 3). to study the relationship between soil quality and light intensity in areas under large trees and open areas with suitable environments for growing Strelitzia. The study was conducted in the area under large trees and open areas within Wichienmatu School, Trang Province by measuring soil structure, soil moisture, acidity, alkalinity and light intensity, and then recording the measurement results and comparing them to analyze the differences in soil quality and light intensity. According to the study, the area under the big trees has a nodular appearance. It has low moisture value, alkaline soil, and low light intensity. While the soil in the open area is also nodular soil. High humidity value. The soil has alkaline properties and high light intensity. Keywords: Paradise Bird, Soil Quality Light Intensity
