Improving soil fertility
This scientific investigation aims to assess and improve the soil fertility at Chonradsadronumrung School using various organic and inorganic substances. The quality of the soil from the chosen site was tested using the standard protocol from Globe and equipment from Extech. The study site was divided into 6 sections and treated with organic and inorganic substances such as egg shells, oyster shells, shredded papers, fruits, and combined substances while the other section has no treatment (control). 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 was a significant difference (p<0.05) in soil pH, relative humidity, air temperature, and soil temperature measured at 5 cm and 10 cm depth. The organic and inorganic substances can improve the soil fertility at Chonradsadronumrung School and among the treatments, the combined substances are the most effective in increasing the amount of nitrogen (N), phosphorus (P), and potassium (K). In addition, more research should be done to test the other soil properties in the study site and the amount of NPK will be measured after 1 month. Keywords: Soil Fertility, soil parameter, ANOVA and Tukey HSD Test
