Abstract

How do different percentages (15%, 10%, 5%, 0%) of biochar in soil affect the initial growth rate and final mass of radish plants (Raphanus sativus). We used 15%, 10%, 5% biochar, and using pure soil as our control group. For each soil type, we prepared 12 samples, totaling 48 samples across all conditions. After germination and initial plant growth, the number of leaves and the plant’s height from the top of the plant to the soil (in centimeters) were recorded every school day. The purpose of this study is to better understand if biochar is an effective way to stimulate plant growth in radish, producing healthier and faster-growing plants.
