This current study aims to investigate the relationship between high NPK concentrations in the soil and the resulting changes in floral diversity within the coastal zone of Samet, Chonburi, Thailand. The quality of the soil from the chosen site was tested using the standard protocol from Globe and equipment from Extech. Then, plants thriving in the study site was identified and recorded. The results of the different experiments were observed, gathered, and compared using one-way ANOVA and Tukey HSD Test. Based on the experimentations, results and gathered data, the researchers concluded that there are significant differences (p<0.05) in soil temperature measured at 5 cm, air temperature, and relative humidity, but there was no significant difference (p>0.05) in soil pH, soil temperature at 10 cm, and NPK concentration. Furthermore, greater NPK concentrations have a significant impact on floral diversity in Samet, Chonburi, Thailand. Lastly, to strengthen this study, more research is required by comparing the soil quality in Samet's coastline area and nearby districts, as well as the types of plants that thrive in these areas.
