Abstract
The objective of this research experiment was to investigate the effectiveness of using biochar in potting soil in terms of plant growth and soil quality. This experiment was carried out using varying amounts (0%, 5%, 10%, and 20%) of biochar in the soil to see its effect on seed germination, plant growth, and soil quality such as pH, water retention, and soil temperature. The aim of the experiment was to identify whether biochar can be used in soil to promote healthier and stronger plants. There were four treatments which included 0% (Control), 5% (Treatment 1), 10% (Treatment 2), and 20% (Treatment 3). All treatments had five replicates which involved the planting of lettuce seeds under a controlled environment inside the greenhouse. Data about plant growth was collected every week based on the height, leaf count, and coloring of the leaves. Data from the harvest included biomass and the ratio between roots and shoot length. Post-harvest, soil analysis was carried out to check for changes in the soil quality. The experiment was conducted for eight to ten weeks. ANOVA was also used to analyze results
